    专利说明:

    The invention relates to an energy supply system for supplying several groups of consumers with electrical energy, each group being connected via its own electricity meter to a public energy supply network.
    The use of a large number of electrical consumers in residential buildings and in commercial and industrial enterprises leads to a correspondingly high power consumption from public energy supply networks. At the same time, however, users want as little as possible to pay for energy purchased from the public grid. For this reason, energy supply systems are known from the prior art, which enable at least partial supply of electrical consumers with self or locally generated energy and thus partially, or in a so-called island operation completely, independently of public energy supply networks.
    EP 2 293 409 A2 discloses an island energy network comprising a plurality of interconnected island units. Each island unit has, among other things, a photovoltaic system, an energy storage device and a connection to a consumer. The energy generated by an in-house photovoltaic system can thus be consumed or stored in the same house. In addition, excess energy generated by one island unit may be provided via the island power grid to another island unit for consumption or storage. Likewise, in the case of too low self-generated energy, the missing order can be provided by another island unit. For the decentralized control of the energy flows, means for communication with other island units are provided and designed to send corresponding requests to other island units or to receive them from other island units.
    WO 2014/023724 A2 discloses a photovoltaic storage system for supplying consumers in a household with solar energy, with an energy storage and a control device. The control device is coupled to at least one of the consumers and switches it off when more than the currently required energy is generated by the photovoltaic system in order to charge the energy storage more efficiently. In contrast, the consumer is switched on if less than the currently required energy is generated by the photovoltaic system in order to optimize the energy withdrawal from the energy store. The photovoltaic storage system can also be connected to an electrical supply network.
    The known from the prior art Energieversorgungssyste¬me are thus designed for the supply of consumers with locally generated or from a public energy supply network related energy. In particular, in-house photovoltaic systems are provided in order to supply the household with locally generated energy and to feed any surplus energy into a public or an internal energy supply network. However, the use of a separate photovoltaic system per household, possibly with its own energy storage, is cost-intensive, since in addition to the installation costs incurred, surplus local energy can often only be supplied to the public energy supply network at predetermined, generally low rates. Even if present an island power network with several In¬seleinheiten, each having a photovoltaic system, the locally generated energy can not be used in an optimal way. be divided into island units, since this would require a coordinated control of the energy flows between the Inselein¬heiten and a vote of the capacities of the individual photovoltaic systems.
    It is an object of the invention to provide a power supply system as stated above, which reduces both the costs incurred by the installation costs and the energy costs incurred by the operation of the consumer, and in particular a maximum optimal use of locally generated energy by several groups of consumers allows. In addition, the energy supply system should ensure the most reliable possible supply of energy.
    To this end, the invention provides a power supply system as defined in claim 1. Advantageous embodiments and further developments are indicated in the dependent claims.
    According to the invention, each group is additionally connected via its respective inverter to a single local power supply system which is common to all groups, each inverter being controllable with a central power supply
    Control device is connected, which is designed to set the each of the inverters to the group and / or the public power supply network to be provided elek¬trischen power. Here, a group of usurers is understood to mean a set of electrically operated appliances or consumers of electrical energy, all of which are connected to a public energy supply network via a common electricity meter. Thus, for example, a single group may comprise the quantity of consumers in a single-family house, a residential unit in an apartment building, a commercial enterprise or an industrial enterprise. In order to supply each group with locally generated energy in addition to the energy from a public energy supply network, each group is additionally connected to one respective inverter, all inverters being connected to a single local energy supply system common to all groups.
    In contrast to systems known from the prior art, therefore, not every group is equipped with its own local energy supply system. The installation of a single local power supply system to supply all groups of consumers can be much cheaper than the installation of individual systems. This becomes particularly clear when a large number of groups, for example 10, 100 or more groups, draw energy from the common local energy supply system. The energy supply system is thus provided for the connection of a corresponding number of residential units or other groups, for example a whole place of residence, to the local energy supply system.
    In order to divide the locally generated energy as efficiently as possible and according to the needs of the individual groups, a central control device is provided, with which each inverter is controllably connected. For this purpose, the control device is designed to set the electrical power to be provided by each inverter to the connected group and / or the public power supply network.
    The control device can also be designed for inputs by one or more users, so that the function of the control device can be influenced by means of these inputs. The power to be provided can vary and be determined by the control device, for example as a function of user input or empirical values, or as a constant or slowly variable one. For example, estimated size is present in the controller. Should the power thus provided not suffice for the supply of the respective group, additional energy can be obtained from the public energy supply network, while in the case of local energy provided beyond the demand, the excess energy can be fed into the public energy supply network. The control device thus determines how much electrical power is transported via each individual inverter and in this way ensures the distribution of the locally generated energy to the consumers who are currently in need of electricity and of all groups. This is a significant advantage of a central control device in relation to distributed decision-making units, since the central control device can acquire information about the entire energy supply system and can take into account various factors influencing the determination of the optimal allocation to the groups.
    According to an advantageous embodiment of the invention, the control device for adjusting the power to be provided by each inverter is arranged with first sensors arranged between each group and the public power supply network and connecting the power requirements of each group. With the first sensors, the control device determines the current reference for the operation of the consumers from the public energy supply network and thus the exact power requirement of each group. Accordingly, the control device controls the inverters assigned to the respective group in order to provide the power required by the group not via the public power supply network but via the inverters and thus via the local power supply system. In this way, each group of consumers is only supplied with that power which is actually actually required. Thus, it is also prevented to deliver individual groups in excess of the demand performance and to feed the excess at generally unfavorable rates in the public energy supply network, while other groups mayuccess have to include power from the public power grid. In particular, in the case of too little available local energy, it can be prevented by suitable control of the inverters that the same groups always have to obtain expensive energy from the public energy supply network.
    If the control device for detecting the locally available electrical power is connected to second sensors arranged between the local energy supply system and the inverters, the control device can carry out the distribution of the local energy even more efficiently to the groups of consumers. For example, if the needs of the groups are not accurately known, the distribution of the available power to the groups may be according to a predetermined ratio. Thus, a user of a group of consumers, who has provided more financial resources for the common local energy supply system, also more locally generated energy can be made available. Even with a known requirement of the groups and for their supply too little locally available power, the control device can control the distribution of power according to predetermined criteria.
    The locally generated energy can be used particularly efficiently if an electrical energy store with a charge regulator is arranged between the local energy supply system and the inverters, the second sensors for detecting the locally available power with the energy store and preferably also with the local energy supply system are connected, and the charge controller is connected to the controllable charge of Energiespei¬chers with the control device. In this way, locally generated energy beyond the needs of the groups can be stored in the energy storage, for which purpose the charge controller controllable by the control device is provided. Thus, the control device can fall back on the stored energy for the supply of the groups, if the currently locally generated energy is insufficient for their supply. In addition, both the energy currently generated and the energy stored in the energy store, for example a battery, can be detected with the second sensors and transmitted to the control device. With this information, the control device can determine whether the energy store is to be loaded and determine what proportion of locally generated energy beyond the needs of the groups should be used for a possible charge of the energy store. Under the "available power" is essentially the sum of the currently generated power or energy and the energy store removable power or energy to understand.
    When the control device is designed, in the case of a locally available, locally available power, it is particularly advantageous to have the power requirement recorded for each group plus a proportion of the locally available power exceeding the requirements of all groups as electrical power to be provided on the respective one to assign the inverter assigned to the group. In this way, for example, the controller may control the inverters to feed excess locally generated energy and / or energy stored in an energy store into the public power grid. Specifically, if the power demand of each group is known, the amount of any power to be fed into the public power grid Energy are expediently divided among the inverters and thus the financial reimbursement to the users of the groups are controlled. For an efficient use of the locally generated energy, it is also expedient that, when the electric energy store is completely charged, the sum of the components to be provided via the inverters in addition to the detected power demand is at least the locally generated power beyond the requirements of all groups. The control device can thus, if a further charge of the energy storage is not required to control the inverter to feed in addition to the complete supply of groups together at least the excess locally produced power, but possibly also a portion of energy stored in the energy storage in the public Ener¬ gieversorgungsnetz. In addition, the control device controls the distribution of this excess power to the inverters.
    In order to be able to fully utilize excess locally generated power even at a later point in time, it may also be provided that the sum of the components to be provided via the inverters in addition to the detected power requirement is less than that above the requirement when the electrical energy store is not completely charged for charging the energy store is locally generated power beyond all groups. Thus, the controller may use the locally generated power beyond the needs of all groups completely or only partially for the charge of the energy store. In the latter case, according to which only part of the excess locally generated power is used for the storage charge, the remainder of the surplus power can be fed via the inverters into the public energy supply grid. The control device can thus, by targeted control of the inverter, use the entire locally generated power at the same time for the supply of the groups with the exactly required amount of power, for charging an energy store and for feeding into a public energy supply network.
    If the controller is configured to set the proportion of the proportions to each other according to user inputs, the users of the groups may specify the distribution of the surplus locally available power to the inverters. For example, the share to be provided via a particular inverter in addition to the sensed power demand may be greater when compared to portions provided by other inverters when the user powered by this inverter has provided more financial resources for the establishment of the power system. This user thus receives a higher reimbursement for energy fed into the public power grid.
    According to a further preferred embodiment of the invention, the control device is connected to at least one consumer and designed to activate and deactivate this consumer automatically and / or user inputs. Hereby, consumers can be switched on and off individually via the control device. An automatic activation and deactivation by the control device can take place depending on user preferences entered into the control device, for example depending on the time of day or the presumable presence of the user. Likewise, the activation and deactivation can be done manually by the user, this manual instruction preferably having a higher priority than the automatic instruction. For a reliable supply of the consumers with locally generated electrical energy, it is favorable if the control device is designed to automatically deactivate at least one consumer, preferably user inputs, in the case of a locally available power which does not satisfy the needs of all groups or not, and optionally re-enable further user input. The control device preferably has user inputs, which show which consumers can be temporarily deactivated in the event that too little power is available locally, or if they are not activated at all during this period of too little local power. Also, the user inputs may include information about the maximum duration of non-supply of individual consumers. In this way, the probability of being able to supply all essential consumers with locally available power can be increased. In order nevertheless, if necessary, to enable the supply of these selected consumers, it is expedient to override the automatic control instruction and to be able to carry out the activation manually by means of the control device.
    In order to be able to operate the energy supply system independently of a public energy supply network, it is preferably provided that the control device is connected to at least one separating device arranged between a group and the public power supply network for the controllable disconnection of the group from the associated public energy supply network is. Of course, a separation device can be provided for each group of the energy supply system. In the event that too little power is locally available and the groups are disconnected from the public power grid, predefined consumers may also be temporarily deactivated or may not be activated during that period of too little local power.
    With regard to the installation costs and the feasibility of the power supply system, it is particularly advantageous if the local power supply system is a photovoltaic system. In particular, a photovoltaic system provided for supplying a large number of groups can be constructed on essentially a suitable surface, without having to take into account special impairments on the part of the user, such as, for example, the shadow of a wind turbine. It is self-evident, however also possible, other Ar¬ten of local energy supply systems, such as Wind turbines or hydropower plants to use.
    In order for the control device to be able to provide the users with an overview of the services flowing between the groups and the public power supply network, the control device for detecting the energy supplied from the public power supply network or fed into the public power supply network is advantageously one with each group connected electricity meters connected. In addition, this information can be used to bill the electricity bill among the users. For example, a user who was disadvantaged due to the control device with regard to the purchase of electricity from the public power grid can be compensated by means of compensation payments. For the control of the power flows it is expediently provided that the control device has an Internet interface and is designed to receive requests for the supply of locally available power into the public power grid and, if appropriate, to control the inverters for such an infeed. The Internet interface, which may be wireless or wired, thus allows an operator of a public power grid to report a need for any energy available in the power system. The control device can subsequently take into account various decision criteria. User input decides whether locally available power should be fed into the public grid. If so, the controller controls the inverters accordingly. In particular, locally generated power and / or energy stored in the energy store can be fed in currently beyond the needs of all groups. A decision criterion may be, in particular, the tariff currently valid for the feed, so that the control device, for example, feeds energy stored in the energy store when the current tariff is favorable for the user.
    In order to be able to estimate the power requirements of the groups and the power that will probably be generated locally soon, it is additionally provided that the control device has an Internet interface and is designed to execute its control functions depending on weather data received via the Internet interface. Thus, the controller may consider expected weather conditions in the control of the inverters. For example, the controller would not empty the energy storage when little or no sunshine is expected to be generated by solar power, or when the weather conditions increase the users' electricity demand, for example, to operate electric heaters or air conditioners.
    However, the controller's Internet interface may also be used for inputting user preferences or for interfacing with sensors for acquiring measurement data, such as the first and second sensors. In particular, the controller may be configured for remote control, for which corresponding control instructions are transmitted via the Internet interface.
    In order to further increase the security of supply of the consumers with energy, it is favorable, if to charge the electrical
    Energy storage with energy from the public Energieversor¬gungsnetz the inverters are designed for bidirectional power transport and the control device is designed to set the electrical power to be provided by each inverter to the electrical energy storage connected thereto. As a result, the energy store can be stored even if the locally generated power is insufficient for a storage charge. The control device can carry out the charge of the energy store, in particular in a time interval in which the power purchase is possible at a tariff that is favorable for the user. In addition, by being able to be constantly charged, it is also possible to cover the average power demand of the consumers via the locally generated power and, if necessary, to make use of the stored energy. Thus, the An¬schlussleistung for a supply from the public Ener¬gieversorgungsnetz can be reduced to reduce costs. The charging of the energy storage device with electricity from the public energy supply network would then take place with a reduced connected load over a correspondingly longer period of time.
    Although the power supply system may be formed with single-phase inverters, it is advantageously provided for locally operated power consuming loads requiring three current-phase loads that the inverters are three-phase.
    The invention will be further elucidated below on the basis of preferred, non-limiting exemplary embodiments with reference to the drawing.
    Fig. 1 shows schematically an embodiment of a Energiever¬sorgungssystems according to the invention, and
    FIG. 2 shows a relationship between powers occurring in the energy supply system.
    The energy supply system 1 illustrated in FIG. 1 is connected via a domestic network 2 to a public energy supply network 3, with one each between the household network 2 or the public energy supply network 3 and groups G1-G4 of consumers, for example individual households Electric meter 4.1-4.4 is provided in order to be able to grasp the power supplied from the public power grid 3 or the power fed thereto. Although the embodiment in FIG. 1 shows four groups G1-G4 of consumers, a smaller, but in particular a significantly larger number, of groups can of course be supplied via the energy supply system 1. Accordingly, the number of all other components assigned to exactly one group would also change.
    Starting from the exemplary four groups G1-G4, each group G1-G4 is additionally connected to a single local power supply system 6 common to all groups G1-G4 via one, preferably bi-directional, inverter 5.1-5.4, in order to produce the groups G1-G4. Preferably, the local power supply system 6 is a photovoltaic system. In order to be able to set the power to be set for the groups G1-G4 or the public power grid 3 via the inverters 5.1-5.4, each inverter 5.1-5.4 is controllably connected to a central control unit 7. The groups G1-G4 are thus not directly connected to the local power supply system 6, since on the one hand a direct connection would not allow control of the powers to be delivered to the respective groups G1-G4 and the public power supply network 3 and, on the other hand, the outputs of the electricity meters 4.1-4.4 would be short-circuited via the common connection point at the local power supply system 6.
    In order to detect the power demand of each group G1-G4 and accordingly to be able to adjust the power to be provided by each inverter 5.1-5.4, the control device 7 is connected to first sensors 8.1-8.4 arranged between each group G1-G4 and the public power grid 3.
    In addition, in order to be able to detect the locally available electrical power, the control device 7 is also connected to second sensors 9.1, 9.2, which are arranged between the local energy supply installation 6 and the inverters 5.1-5.4.
    So that the groups G1-G4 can be operated with local energy even if the locally generated photovoltaic power alone is insufficient for supplying the groups G1-G4, an electrical energy store 10 is located between the local energy supply installation 6 and the inverters 5.1-5.4 arranged with a charge controller 11. The charge controller 11 is likewise connected to the control device 7, so that the control device 7 corresponds to different criteria, if appropriate also according to user input, cf. Also, the input unit 7 'in Fig. 1, determine whether and with what power of the local power supply system 6 or the public Energieversorgungsnet¬zes 3 of the energy storage device 10 is to be loaded.
    The control device 7 is additionally connected to at least one consumer in order to correspondingly activate and deactivate these automatic and / or user inputs. According to the example in FIG. 1, the control device 7 is connected to the groups G1-G4 so that in each case at least one consumer of these groups G1-G4 can be activated and deactivated. In addition, a separation device 12.1-12.4 connected to the control device 7 is provided between each group G1-G4 and the public power supply network 3 or the home line network 2, so that the groups G1-G4 can be disconnected from the public power supply network 3 and the power supply system 1 only locally available energy can be operated. The control device 7 is connected to the electricity meters 4.1-4.4 in order to detect and process any energy received from or fed into the public energy supply network 3.
    The control device 7 preferably has an Internet interface 13. Hereby, for example, an operator of a public power supply network 3 can apply for energy supply from the energy supply system 1, so that locally generated energy also benefits consumers who are not connected to the energy supply system 1. In addition, weather data can be received via this interface 13 (and, for example, the input unit 7 ').
    Although the power supply system 1 is illustrated in FIG. 1 with three-phase inverters 5.1-5.4, it is also possible to use single-phase inverters in order to supply only consumers connected to a single phase with locally generated energy. Thus, consumers connected to the other phases would e.g. be supplied with power from the public power grid 3.
    The controller 7 controls the inverters 5.1-5.4 to supply a power set by the controller 7 to the groups G1-G4 and, if necessary, simultaneously to the public power grid 3. For this purpose, the control device 7 determines the power requirement of the groups G1-G4 by means of the first sensors 8.1-8.4, the locally generated power by means of the second sensors 9.1 and the storage charge of the energy store 10 by means of the second sensors 9.2.
    FIG. 2 shows an example of powers occurring in the energy supply system 1. Here, P1-P4 designates the respective power requirements of the groups G1-G4 and P6 the power currently generated by the local power supply 6, which exceeds the power demand of the groups G1-G4. The excess power Px = P6-P4-P3-P2-P1 which is not required for the supply of the groups G1-G4 can thus be used completely or only partially for the charge of the energy store 10, if this is not completely charged. Should there still be a surplus of excess power Px in spite of charging the energy storage 10, this remainder may be fed into the public power grid 3 at the same time as charging the energy storage 10 and supplying electrical power to the groups G1-G4. If, however, in an example not shown, the available power, i. the power currently generated by the local energy supply system 6 and the power which can be removed from the energy storage device 10 is less than the power requirement of the groups G1-G4 can either be supplied to the groups G1-G4 with energy from the public energy supply network 3 or individual consumers are consumed of the groups G1-G4 deactivated by the control device 7 in order to try to cover the thus reduced power requirement of the groups G1-G4 with locally generated energy.
