At present, with the improvement of the living standard of people, the country pays more and more attention to the sustainability of resources and renewable energy sources. However, most of the electric power used by the current urban power supply network is from a rigid commercial power system, so that the urban power supply network is not easy to be flexible, and the traditional power generation mode adopted by the urban power supply network can also generate a great pollution phenomenon.

Solar energy is widely concerned as an energy source which can be used in any place where the sun exists, and the use of the solar energy is gradually shifted from the initial use in remote areas and areas with power shortage to the use in cities of developed countries; the solar panel can be well combined with a building from the simple use and installation of the solar panel to the prior art, so that the solar photovoltaic power generation has wider development space. Generally, a solar cell module is installed on the roof of a house or a building, a leading-out terminal is connected with a public power grid through a controller and an inverter, and a photovoltaic matrix and the power grid are connected in parallel to supply power to a user, so that a user grid-connected photovoltaic system is formed. The solar photovoltaic power generation glass curtain wall has the functions of peak regulation and environmental protection, and can be used for replacing common curtain wall glass with a solar photovoltaic power generation glass curtain wall, so that the solar photovoltaic power generation glass curtain wall can be used as a building material and can generate power, the cost of photovoltaic power generation is further reduced, the solar photovoltaic power generation glass curtain wall is unique, becomes a beautiful landscape in cities, and can also be directly used as a building material.

Therefore, how to combine solar energy into an urban power supply network to achieve the purposes of optimizing the urban power supply network, saving energy and reducing emission is a problem to be solved urgently by researchers at present.

In view of the above problem, referring to fig. 1, an embodiment of the present invention provides an energy coupling system 01(01-1, 01-2, and 01-3), including: building photovoltaic power generation subsystems 11(11-1, 11-2 and 11-3) and energy subsystems 12(12-1, 12-2 and 12-3) connected with commercial power;

the building photovoltaic power generation subsystem 11 is connected with the energy subsystem 12 and is used for supplying the electric energy generated by the building photovoltaic power generation subsystem 12;

the energy subsystem 12 is used to provide energy to energy consuming devices located in the building complex.

Optionally, referring to fig. 1, the energy coupling systems are arranged in a building cluster (each energy coupling system corresponds to a building cluster), and the building cluster includes at least one city building. For example, a building cluster can be a residential area, a building photovoltaic power generation subsystem can be installed on each building floor in the residential area, and one or more energy subsystems exist in the residential area and are used by new energy vehicles in the residential area; or each building in the whole residential area can be provided with one set of energy coupling system; although the residential area may be a larger (e.g. a city) or smaller building cluster (e.g. a first room of a certain area), the invention is not limited to the building cluster.

Alternatively, as shown with reference to FIG. 1, the energy subsystem 12 includes a building energy module 121(121-1, 121-2, and 121-3) and a traffic energy module 122(122-1, 122-2, and 122-3);

a building energy module 121, configured to provide energy for devices in the building cluster; and a traffic energy module 122 for providing energy to the vehicle connected to the traffic energy module.

For example, since the embodiment of the present invention does not specifically limit the building cluster, the building cluster may be a residential building, an industrial building, or a public infrastructure, and the devices in the building cluster may be air conditioners, household appliances, or the like used by residents, large machines used by industrial buildings, or a public infrastructure in which street lamps are set on roads.

Optionally, referring to fig. 2, the transportation energy module 122 includes an electric vehicle charging submodule 1221 and/or a hydrogen production hydrogenation submodule 1222;

the electric vehicle charging submodule 1221 is configured to charge a first electric vehicle connected to an output interface of the electric vehicle charging submodule 1221; for example, in practice, in order to enable a vehicle owner to perform a subsequent stroke after the vehicle owner is charged more quickly, a power transmission interface of the charging submodule of the electric vehicle may be a quick charging gun; the charging submodule of the electric vehicle is provided with an inverter and a transformer so as to convert high-voltage alternating current from commercial power into low-voltage direct current suitable for charging the electric vehicle;

a hydrogen production and hydrogenation submodule 1222 for providing hydrogen to a first fuel cell vehicle coupled to the output interface of the hydrogen production and hydrogenation submodule 1222; for example, the hydrogen production and hydrogenation sub-module may generate hydrogen by electrolyzing water, and in order to supply enough electricity to the commercial power and the building photovoltaic power generation sub-system, the hydrogen production and hydrogenation sub-module may further include a backup power supply, and the backup power supply may store a part of the electric energy for subsequent use when the commercial power or the building photovoltaic power generation digital system supplies enough electricity to the hydrogen production and hydrogenation sub-module.

Optionally, in order to avoid that the utility power cannot be used and the building photovoltaic power generation subsystem cannot be used, for example, in case of power failure of the utility power at night, the energy coupling system 01 further includes an energy storage subsystem 13 connected to the utility power and the building photovoltaic power generation subsystem 11;

the energy storage subsystem 13 is used for acquiring and storing electric energy from the commercial power and/or the building photovoltaic power generation subsystem 11;

the energy storage subsystem 13 is connected with the energy subsystem 12 and is used for supplying the self-stored electric energy to the energy subsystem 12.

It should be noted that, in practice, building clusters are generally provided with building standby power supplies, the energy storage subsystem in the embodiment of the present invention may include an original building standby power supply, the building standby power supply may also be connected to the energy storage subsystem and the commercial power, or the building standby power supply may also be connected to the building photovoltaic power generation digital system and the commercial power, which is not limited herein.

The above embodiment provides an energy coupling system, because the system includes: the system comprises a building photovoltaic power generation system and an energy subsystem connected with commercial power; the building photovoltaic power generation subsystem is connected with the energy subsystem and is used for supplying the electric energy generated by the building photovoltaic power generation subsystem to the energy subsystem; the energy subsystem is used for providing energy for energy consumption equipment in a building cluster where the energy coupling system is located. When the energy coupling system provided by the embodiment of the invention is used, when the commercial power meets a first preset condition, the building photovoltaic power generation subsystem is controlled to supply power to the energy subsystem; when the commercial power meets a second preset condition, controlling the building photovoltaic power generation system and the commercial power to supply power to the energy subsystem; therefore, the building photovoltaic power generation subsystem can be flexibly used to supply the total electric energy generated by the building photovoltaic power generation subsystem to the energy subsystem under different conditions by combining with the condition of commercial power. Because the building photovoltaic power generation subsystem is arranged on a building, the building can be conveniently supplied with power, and in addition, the coupling with the energy subsystem is realized, so that the electric energy required by the whole building group corresponding to the energy coupling system can be supplied by commercial power and the building photovoltaic power generation subsystem according to different conditions, the power supply network of the whole building group is optimized, and because the electric energy of the whole building group can use a pollution-free power generation mode, namely, the electricity generated by the building photovoltaic power generation subsystem corresponding to the solar power generation, the pressure of the commercial power is shared, the use of the electricity generated by the traditional high-pollution high-emission power generation mode is reduced, the solar energy is fully utilized, and the purposes of energy conservation and emission reduction are achieved; furthermore, whether the building photovoltaic power generation subsystem is used alone or combined with the building photovoltaic power generation subsystem and the commercial power to supply power is determined according to different conditions, a flexible power supply network is built, the power supply mode can be adjusted under different conditions, energy conservation and emission reduction are achieved, and the reliability of power utilization of the building group corresponding to the energy coupling system is fully guaranteed.

Referring to fig. 3, an embodiment of the present invention further provides a method for controlling an energy coupling system provided in the foregoing embodiment, including:

101. and judging whether the commercial power meets a first preset condition.

When the commercial power meets a first preset condition, executing 102; and when the commercial power does not meet the first preset condition, executing 103.

Illustratively, the first preset condition includes at least any one of: the commercial power is cut off, the commercial power is in the power consumption peak period at the current moment, and the power price of the commercial power at the current moment is larger than or equal to the preset threshold value.

102. And controlling the building photovoltaic power generation subsystem to supply power for the energy subsystem.

Specifically, under the condition of mains supply outage, the mains supply cannot supply power to the energy subsystem, so that the building photovoltaic power generation subsystem needs to be used for supplying power to the energy subsystem at the moment; in practice, the electricity used by the energy subsystem is commercial electricity, because commercial electricity provided by commercial power is changed at any time, generally, the electricity price in an electricity utilization peak period, such as six to eight hours in the afternoon, is high, so that when the electricity price is higher than a certain value, the electricity utilization peak period can be determined, and at this time, for a user belonging to the energy coupling system, the commercial power is not cost-effective, so that the electricity generated by using the building photovoltaic power generation subsystem is better, the pressure of the commercial power is shared, and the effect of reducing the peak value is achieved.

Illustratively, referring to fig. 4, when the energy subsystem includes a building energy module and a traffic energy module, the step 102 specifically includes:

1021. and controlling the building photovoltaic power generation subsystem to supply power to the building energy module so that the building energy module provides energy for equipment in the building cluster.

1022. And controlling the building photovoltaic power generation subsystem to supply power to the traffic energy module so that the traffic energy module provides energy for the vehicle connected with the traffic energy module.

Illustratively, referring to fig. 5, when the transportation energy module includes an electric vehicle charging sub-module and/or a hydrogen production hydrogenation sub-module, the step 1022 specifically includes:

and controlling the building photovoltaic power generation subsystem to supply power to an electric vehicle charging submodule and/or a hydrogen production hydrogenation submodule included in the traffic energy module so as to enable the electric vehicle charging submodule to charge a first electric vehicle connected with an output interface of the electric vehicle charging submodule and enable the hydrogen production hydrogenation submodule to produce hydrogen and provide the hydrogen to a first fuel cell vehicle connected with the output interface of the hydrogen production hydrogenation submodule.

103. And controlling a building photovoltaic power generation system and commercial power to supply power for the energy subsystem.

Specifically, at this time, the utility power does not satisfy the first preset condition, and then satisfies a second preset condition opposite to the first preset condition, and for example, the second preset condition at least includes any one of the following: the commercial power is not in the power consumption peak period at the current moment, and the power price of the commercial power at the current moment is smaller than a preset threshold value;

under the condition that the commercial power meets the second preset condition, the commercial power is not expensive and can meet the use of the energy subsystem in the energy coupling system in the power consumption peak period, but in order to share the pressure of the commercial power and achieve the purposes of energy saving and emission reduction, the commercial power is used as little as possible, and clean energy is used, so that the building photovoltaic power generation subsystem and the commercial power are used for supplying power to the energy subsystem on the basis of ensuring the stable operation of the energy subsystem. The specific electric quantity of the commercial power and the building photovoltaic power generation subsystem can be supplied to the energy subsystem in the energy coupling system after the electric quantities of the commercial power and the building photovoltaic power generation subsystem are transmitted into the same bus as shown in fig. 2, and the electric quantities of the commercial power and the building photovoltaic power generation subsystem account for the bus according to actual conditions.

Certainly, it should be noted that, in order to ensure the electric energy requirement of the device corresponding to the energy coupling system, if the power generation capability of the building photovoltaic power generation subsystem in the energy coupling system is not enough for the energy subsystem to use, even if the commercial power meets the first preset condition, the commercial power and the building photovoltaic power generation subsystem need to be matched to supply power to the energy subsystem; at this time, no matter how the commercial power is, step 103 should be executed, and the same reason is followed when the building photovoltaic power generation subsystem is separated from the commercial power to supply power independently.

Illustratively, referring to fig. 4, when the energy subsystem includes a building energy module and a traffic energy module, the step 103 specifically includes:

1031. and controlling a building photovoltaic power generation system and commercial power to supply power to the building energy module so that the building energy module provides energy for equipment in the building cluster.

1032. And controlling a building photovoltaic power generation system and commercial power to supply power to the traffic energy module so that the traffic energy module provides energy for the vehicle connected with the traffic energy module.

Illustratively, referring to fig. 5, when the transportation energy module includes an electric vehicle charging sub-module and/or a hydrogen production hydrogenation sub-module, step 1032 specifically includes:

and controlling a building photovoltaic power generation system and a commercial power to supply power to an electric vehicle charging submodule and/or a hydrogen production hydrogenation submodule included in the traffic energy module so as to enable the electric vehicle charging submodule to charge the first electric vehicle, and enable the hydrogen production hydrogenation submodule to produce hydrogen and provide the hydrogen for the first fuel cell vehicle.

Optionally, referring to fig. 4, in practice, the building photovoltaic power generation subsystem may not generate power at all times, in rainy days or at night, the power generation efficiency is not high or low, once the battery therein is no longer powered, the battery cannot be used, and at this time, all the power consumption devices corresponding to the energy coupling system need to be powered by the commercial power, so the control method further includes, before step 101:

100. and judging whether the building photovoltaic power generation subsystem can work normally or not.

When the building photovoltaic power generation subsystem cannot work normally, executing 101A; when it is determined that the building photovoltaic power generation subsystem can be used normally, 101 is executed.

101A, controlling the power supply of the energy subsystem by commercial power.

Optionally, referring to fig. 4, when the energy coupling system includes the energy storage subsystem shown in fig. 2, the control method further includes:

106. and controlling the building photovoltaic power generation subsystem to store the residual electric energy except the supplied energy subsystem in the total electric energy generated by the building photovoltaic power generation subsystem in the energy storage subsystem.

Specifically, the step 106 is executed when the utility power meets the first preset condition or the second preset condition, because when the power generation capacity of the building photovoltaic power generation subsystem is sufficient, extra electric quantity is inevitably generated in addition to the power supply for the energy subsystem, and the extra electric quantity is stored in the energy storage subsystem to avoid waste.

107. And controlling the energy storage subsystem to supply power to the energy subsystem.

Step 107 is executed when the commercial power meets a first preset condition; when the commercial power meets the first preset condition, the reason for independent power supply of the building photovoltaic power generation subsystem after the energy storage subsystem and the step 102 is the same, and the description is omitted here. Since the energy storage subsystem can only be powered by electricity, step 107 is performed after step 106.

Optionally, when the utility power meets a second preset condition, the utility power is sufficient and the price is not high, so to avoid power consumption of the electric equipment corresponding to the energy coupling system in a later power consumption peak period or power failure, the energy storage subsystem may obtain and store electric energy from the utility power at this time, but if the electric energy stored in the energy storage subsystem is sufficient or full, only the electric energy needs to be reserved for subsequent use, if the electric energy in the energy storage subsystem is not sufficient, the electric energy needs to be charged, in that case, the electric energy needs to be charged, otherwise, as shown in fig. 4, the control method further includes, after the utility power meets the second preset condition:

108. and when the electric quantity stored in the energy storage subsystem is smaller than the preset electric quantity, controlling the energy storage subsystem to obtain electric energy from the commercial power and store the electric energy.
