    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The present invention relates to a local energy production and management system, and to a method for operating said system. It fits into the technical sector of energy management.
    [0007]
    [0008] BACKGROUND OF THE INVENTION
    [0009]
    [0010] The local energy consumption, understood as the local one corresponding to an individual consumer or a limited group of consumers or hotels, non-industrial consumers in general, corresponds basically to the power supply of electric energy receivers, and for air conditioning (cold and heat). ) and sanitary hot water generation.
    [0011]
    [0012] The supply of energy comes mainly from the electricity network, or from fuels, although the use of certain renewable energies, such as photovoltaics, has been increasingly implemented.
    [0013]
    [0014] The use of electrical energy in these local consumers -of the grid or photovoltaic for example- is used in the feeding of electric receivers, while the use of fossil fuels is used burning fuels, normally to obtain thermal energy to heat water, well for sanitary hot water supply, or for heating rooms by means of radiators.
    [0015]
    [0016] Certain local consumers are increasingly implementing other types of supplies, mainly photovoltaic energy generators or cogeneration, where a generator is moved by a thermal engine fueled, recovering heat of combustion for heating or cooling (by absorption).
    [0017]
    [0018] However, existing systems present the limitation of the underuse of the energy obtainable from combustion in local facilities.
    [0019]
    [0020] This drawback is overcome by using the system and method of the invention.
    [0021]
    [0022] DESCRIPTION OF THE INVENTION
    [0023]
    [0024] The local production and energy management system of the invention is of the type that is applied to a local consumer, understanding as such a single consumer or limited group of consumers, consumer or hotel communities, non-industrial, electricity, cold and heat whose annual demand has a relation between electricity and heat of approximately 1 to 2 or more.
    [0025]
    [0026] According to the invention, the system comprises:
    [0027] -at least, a generator set (gas, diesel, gasoline or any fuel) for electric power supply, connected to a local distribution network for supply to local electrical loads belonging to the premises of the consumer or consumer community, which it has already been defined that they would be a single consumer or limited group of consumers or hotels, not industrial,
    [0028] -a heat recuperator coupled to the generator set, and connected to a local air conditioning circuit for heat recovery recovered for the purpose of air conditioning the premises and feeding other thermal receivers associated with said premises,
    [0029] -at least, an electric heat pump powered by the generator set, to generate additional heat or cold from the electricity generated by the generator set, and connected to the local air conditioning circuit for the supply of heat or cold for air conditioning purposes. the premises and power supply of other associated thermal receivers, -a photovoltaic generator connected to the domestic electricity distribution network, and
    [0030] -a control unit associated with electric charge and temperature sensors to manage the operation of the generator set, heat pump and power supply from the photovoltaic generator according to the simultaneous requirements of the electric loads premises connected to the domestic distribution network of electric power and air conditioning of the premises and local thermal receivers connected to the local air conditioning circuit.
    [0031]
    [0032] Basically the proposed in the invention is a combustion electric generator (gas, diesel, etc) with electric heat pump to generate cold and heat and to supply electricity, cold, heat and ACS, and a photovoltaic generator to take advantage of solar energy, together with a control unit to manage both the thermal and electrical loads of the whole, making the most of renewable energies.
    [0033]
    [0034] The operation of the system of the invention is carried out by means of the method for operating the local production and energy management system of the invention, which comprises the following steps implemented in a control unit:
    [0035] -monitoring continuously the local demands of electrical energy of local electrical loads connected to a domestic electricity distribution network, and of thermal energy for air conditioning of premises or for supply to thermal receivers associated to said premises through a local air conditioning circuit, through sensors connected to said control unit,
    [0036] -connect a photovoltaic generator to the domestic electricity distribution network for the first supply of electric power to cover the demand for electrical energy detected,
    [0037] - starting a generator in case it is detected by the control unit that the detected electrical energy demand can not be covered with the energy supplied from said photovoltaic generator, connecting said generator set to the domestic distribution network, and feeding said generator generator set to generate enough energy to cover the detected demand and not covered by the photovoltaic generator,
    [0038] -Determine if there is a demand for cold or heat,
    [0039] -in case of cold demand, feed a heat pump, connectable to a local air conditioning circuit to supply the cold generated to the premises for air conditioning purposes, from the photovoltaic generator and also from the generator set in case the energy supplied from the photovoltaic generator is insufficient to generate by said heat pump the cold necessary to cover said cold demand,
    [0040] -in case of heat demand, feed the heat pump from the photovoltaic generator, and
    [0041] -in the case that the power supplied from the photovoltaic generator is insufficient, connect the generating set, after starting it in its case, to the heat pump recovering heat for air conditioning through a heat recovery unit coupled to the generator set and connected to the local air conditioning circuit and to the thermal receivers, and to supply the generator set sufficiently to cover the electric power demand so that the heat pump generates the heat required minus the heat recovered by the heat recovery unit.
    [0042]
    [0043] In the described procedure, it will be understood that there is a demand for cold or heat in addition to if there is a need to heat the premises, if there is excess photovoltaic production and cold or heat can accumulate in cold or heat storage tanks associated with the heat pump, to recover it at the opportune moments of low photovoltaic generation, for example at night.
    [0044]
    [0045] With this configuration and operating procedure, a better use of the combustion energy is achieved, since using fuels to burn them is not profitable, since for example the performance of a gas generator is around 90% and we obtain electricity by 30%, 60% heat, lost by 10%, and with the invention what we do is to use that 30% of electricity with a heat pump with a COP3 or higher performance (with certain brands and situations the COP5 is exceeded) to obtain a 90 % more heat, Total: 150%. The invention therefore configures an optimal model for the use of photovoltaic energy and combustion, since at the moment it tends to separate them, which supposes the overcoming of a technical prejudice extended today. In winter there is excess thermal demand, that if we take advantage of it with a generating set only generating heat, we would have excess electricity generation (since that 30% of electricity production output of the generator would not be used) and in summer we would have it running without taking advantage of the sun to generate electricity mainly and with the inconvenient noise or vibrations at night.
    [0046]
    [0047] The system and method of the invention is therefore configured as ideal for users such as communities of owners or consumers, non-profit most of the time, which may be connected to the network or be isolated network facilities.
