In the related art, the distributed energy is an energy comprehensive utilization system distributed at a user side, a user needs to integrate electric quantity generated by the distributed energy into a power grid, the power grid is generally divided into a plurality of power grids of a platform region according to a power supply range or a power supply region of a transformer, but due to a self-utilization mode of the distributed energy, part of users do not access the electric quantity generated by the self-distributed energy into the power grid, when the electric quantity generated by the self-distributed energy is excessive, only the electric quantity can be wasted, and no reasonable electric quantity planning exists for the part of electric quantity.

In view of this, the embodiments of the present application provide a method, an apparatus, a device, and a medium for controlling access of distributed energy to electric energy storage, based on current electric energy demand of a power grid of a platform and distributed electric energy of distributed energy sources in a current platform, and when the current distributed electric energy can meet the current electric energy demand, a part of the distributed electric energy is accessed to the power grid of the platform, and another part of the distributed electric energy is stored in a storage device. Therefore, the control of accessing and storing the electric quantity generated by all the distributed energy sources in the platform area is realized, the electric quantity is reasonably planned, and the waste of the electric quantity of the distributed energy sources is reduced.

Referring to fig. 1, an embodiment of the present application provides a distributed energy access and electric energy storage control method, which is executed by an electronic device, and includes:

step S101, obtaining the current electric energy demand of the power grid.

The current electric energy demand is the electric energy required by the power grid to meet the power consumption demand of the transformer area at the current moment, and the electric energy required to be accessed again is provided for the electric energy of the fixed power generation equipment. The power generation device may be a power generation device in a power plant.

Specifically, the power required by the load in the transformer area is provided by the power generation equipment and the distributed energy source, so that the transformer area needs to be connected with the power in addition to the power generated by the power generation equipment. For example, when the current time is 2022, 7 months, 1 days, 12:00:00, the electric energy required by the load in the platform is 150kWh, and the electric energy generated by the power generation equipment is 100kWh, the current electric energy requirement is 50kWh.

Step S102, obtaining the distributed electric energy of the current distributed energy source.

The distributed electric energy is the sum of electric energy generated by distributed energy sources of all users in the lower platform area at the current moment.

In particular, the distributed energy source may be one or more. Further, the electric quantity generated by each distributed energy source in unit time at the current time is obtained. When the distributed energy is one, acquiring the electric quantity generated by the distributed energy in unit time, and taking the electric quantity as the distributed electric energy; when the distributed energy sources are multiple, calculating the sum of the electric quantity generated by each distributed energy source in unit time, and taking the sum of the electric quantity as the distributed electric energy.

Step S103, judging whether the distributed electric energy can meet the current electric energy demand according to the distributed electric energy and the current electric energy demand.

When the distributed electric energy is greater than or equal to the current electric energy demand, the distributed electric energy can meet the current electric energy demand.

Specifically, in order to meet the power required by the load in the area, it is necessary to determine whether the distributed power can meet the current power demand. More specifically, the distributed power is compared with the current power demand, and when the distributed power is greater than or equal to the current power demand, the distributed power is described as meeting the current power demand.

And step S104, if the current electric energy requirement can be met, determining the current access electric energy according to the distributed electric energy and the current electric energy requirement, and controlling the distributed energy source to input the current access electric energy to the power grid of the platform region.

Specifically, when the distributed electric energy can meet the current electric energy demand, selecting electric energy which is the same as the current electric energy demand from the distributed electric energy as the current access electric energy. For example, the front power demand is 50kWh and the distributed power is 80kWh, then the current on power is 50kWh.

Further, after determining the current access electric energy, controlling the distributed energy to input the current access electric energy into the district power grid. Specifically, when the distributed energy sources are one, the distributed energy sources are controlled to input current access electric energy into the district power grid; and when the number of the distributed energy sources is at least two, controlling the distributed energy sources corresponding to the current access electric energy to input the current access electric energy into the district power grid. Further, when there are at least two distributed energy sources, one or more distributed energy sources can be selected randomly, and the electric energy generated by the selected distributed energy sources is used as the current access electric energy according to the current electric energy demand. The selection of the current access electric energy is not limited in the embodiment of the application.

Step 105, determining electric energy to be stored according to the current access electric energy and the distributed electric energy, so as to store the electric energy to be stored into the storage device.

Wherein the storage device is for storing electrical energy. In particular, the storage device may be a mechanical energy storage device, an electromagnetic energy storage device, an electrochemical energy storage device, or a phase change energy storage device, etc. For example, the storage device may be a large lithium-ion battery storage device. Further, the number of the storage devices may be one or more.

Specifically, when the distributed electric energy meets the current electric energy demand, there may be excessive electric energy that cannot be connected to the grid of the transformer area at this time, so that the excessive electric energy is not wasted, and the excessive electric energy may be stored. More specifically, a difference between the distributed power and the current access power is calculated, the difference is used as the power to be stored, and the power to be stored is stored in the storage device.

Further, when the distributed electric energy is equal to the current electric energy demand, that is, when the difference between the distributed electric energy and the current access electric energy is 0, the electric energy to be stored is determined to be 0, and the electric energy to be stored is stored in the storage device.

According to one possible implementation manner of the embodiment of the application, when the distributed electric energy can meet the current electric energy demand, redundant electric energy can be stored, and when the distributed electric energy cannot meet the current electric energy demand, the rest electric energy is required to be accessed to meet the electric energy required by the load in the platform area. Specifically, in step S103, after determining whether the distributed power can meet the current power demand, referring to fig. 2, step S104', step S105', and step S106' may further be included, where:

And step S104', if the current electric energy requirement is not met, controlling the distributed energy source to input the distributed electric energy into the district power grid entirely.

Specifically, when the distributed power cannot meet the current power demand, in order to meet the current power demand as much as possible, the distributed power source needs to be controlled to input the distributed power to the grid of the district.

Step S105', determining the electric energy to be input from the electric energy stored in the storage device according to the distributed electric energy and the current electric energy demand.

The electric energy to be input is electric energy to be input to the power grid of the platform region in the storage equipment, and the electric energy to be input is equal to the difference value between the current electric energy demand and the distributed electric energy.

In particular, when the distributed electrical energy cannot meet the current electrical energy demand, the electrical energy stored by the storage device may be input into the utility grid in order to be able to meet the current electrical energy demand. More specifically, the difference between the current power demand and the distributed power is calculated to obtain the power to be input into the power grid of the district, and the same power as the power to be input into the power grid of the district is selected from the power stored in the storage device as the power to be input. For example, the current power demand is 100kWh and the distributed power is 80kWh, then the power to be input is 100kWh-80 kwh=20 kWh at this time.

Step S106', the control storage device inputs the electric energy to be input to the district power grid.

Specifically, after determining the electric energy to be input, the storage device is controlled to input the electric energy to be input into the power grid of the platform area so as to meet the current electric energy demand.

In one possible implementation manner of the embodiment of the present application, as more and more users install distributed energy sources, the distributed energy sources of the district power grid may be one distributed energy source or may include multiple distributed sub-energy sources, when the distributed energy sources of the district power grid include multiple distributed sub-energy sources, in step S104 and step S105, the current access electric energy is determined according to the distributed electric energy and the current electric energy demand, and the distributed energy sources are controlled to input the current access electric energy to the district power grid, and the electric energy to be stored is determined according to the current access electric energy and the distributed electric energy, so as to store the electric energy to be stored in the storage device, which may specifically include: according to the distributed electric energy, determining electric energy generated by each distributed sub-energy source, dividing each distributed sub-energy source into a target sub-energy source and a standby sub-energy source, judging whether the electric energy generated by the target sub-energy source is smaller than the current electric energy demand, if not, determining the current access electric energy from the electric energy generated by the target sub-energy source, controlling the target sub-energy source to input the current access electric energy into a power grid of a platform area, determining the residual electric energy of the target sub-energy source, determining the residual electric energy and the electric energy generated by each standby sub-energy source as electric energy to be stored, storing the residual electric energy into storage equipment of the target sub-energy source, and storing the electric energy generated by each standby sub-energy source into the corresponding storage equipment.

The distributed energy sources comprise a plurality of distributed sub energy sources, each distributed sub energy source corresponds to one storage device, the target sub energy source is the distributed sub energy source with the largest electric energy generated in each distributed sub energy source, and the standby sub energy sources are distributed sub energy sources except for the target sub energy source in each distributed sub energy source. For example, the distributed energy sources include three kinds of distributed sub-energy sources, wherein the first kind of distributed sub-energy source generates 20kWh of electric energy, the second kind of distributed sub-energy source generates 35kWh of electric energy, and the third kind of distributed sub-energy source generates 25kWh of electric energy, and then the target sub-energy source is the second kind of distributed sub-energy source, the first kind of distributed sub-energy source is the standby sub-energy source a, and the third kind of distributed sub-energy source is the standby sub-energy source b.

Each of the distributed sub-energy sources corresponds to one power generation type, for example, the distributed sub-energy sources can be wind power generation energy sources, photovoltaic power generation energy sources and hydraulic power generation energy sources.

Further, after determining the target sub-energy, in order to determine whether the electric energy generated by the target sub-energy can meet the current electric energy demand, it may be determined whether the electric energy generated by the target sub-energy is smaller than the current electric energy demand. Furthermore, when the electric energy generated by the target sub-energy is not smaller than the current electric energy demand, it is indicated that the electric energy generated by the target sub-energy can meet the current electric energy demand, and the current access electric energy can be determined from the electric energy generated by the target sub-energy directly. Furthermore, after determining the current access electric energy, the target sub-energy source can be controlled to input the current access electric energy to the power grid of the transformer area, so that the load electric energy requirement of the transformer area can be met.

Specifically, when the electric energy generated by the target sub-energy source can meet the current electric energy demand, it is stated that the residual electric energy may exist after the electric energy generated by the target sub-energy source removes the current access electric energy, and the electric energy generated by the standby sub-energy source does not need to be input into the power grid of the platform at this time, so that the residual electric energy and the electric energy generated by each standby sub-energy source can be determined as electric energy to be stored, and the electric energy to be stored is stored in the corresponding storage device. For example, the target sub-energy source generates 35kWh of electric energy, the standby sub-energy sources are 20kWh and 25kWh, the current electric energy demand is 30kWh, the remaining electric energy is 5kWh, and the electric energy to be stored is 50kWh.

Further, when the electric energy generated by the target sub-energy source is equal to the current electric energy demand, the remaining electric energy of the target sub-energy source is 0, and only the electric energy generated by each standby sub-energy source is determined to be the electric energy to be stored, and the electric energy generated by each standby sub-energy source is stored in the corresponding storage device.

In one possible implementation manner of the embodiment of the present application, in the foregoing embodiment, after determining whether the electric energy generated by the target sub-energy source is smaller than the current electric energy demand, the method may further include: if the power consumption is smaller than the power consumption, determining first standby power from power generated by the standby sub-power source according to power generated by the target sub-power source and current power demand, determining the power generated by the first standby power and the target sub-power source as current access power, controlling the target sub-power source to input the generated power to the power grid of the platform, controlling the standby sub-power source to input the first standby power to the power grid of the platform, determining second standby power according to the power generated by the standby sub-power source and the first standby power, determining the second standby power as power to be stored, and storing the second standby power to corresponding storage equipment.

The first standby electric energy is equal to the difference value between the current electric energy demand and the electric energy generated by the target sub-energy source, and the second standby electric energy is the electric energy except the first standby electric energy in the electric energy generated by the standby sub-energy source. It should be noted that the second standby power may be 0.

Specifically, when the electric energy generated by the target sub-energy source is smaller than the current electric energy demand, it is indicated that the electric energy generated by the target sub-energy source cannot meet the current electric energy demand at this time. Further, in order to meet the current power demand, the power generated by the standby sub-power source and the power generated by the target sub-power source can be used as the current access power. Specifically, an electric energy difference value between the current electric energy demand and electric energy generated by the target sub-energy source is calculated to obtain electric energy which is required to be accessed to a power grid of the platform area besides the electric energy generated by the target sub-energy source, a first standby electric energy which is the same as the electric energy difference value is determined from the electric energy generated by the standby sub-energy source, and the first standby electric energy and the electric energy generated by the target sub-energy source are used as the current access electric energy. Further, after determining that the electric energy is currently accessed, the target sub-energy source is controlled to input the generated electric energy to the power grid of the platform region, and the standby sub-energy source is controlled to input the first standby electric energy to the power grid of the platform region.

Further, since the distributed electric energy can meet the current electric energy demand, after the first standby electric energy is determined, the rest electric energy except the first standby electric energy is determined in the standby sub-energy sources and is used as the second standby electric energy.
