Embodiment Construction
[0050]It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0051] The embodiment of the present invention provides a solution to construct a power loss function. The function has an upward concave shape in the coordinate system. The function value at the middle point is smaller than the average value of the function at the points on both sides, and the power loss is the smallest. According to the average target power per unit capacity Higher charging and discharging efficiency.
[0052] Such as figure 1 as shown, figure 1 It is a schematic diagram of the terminal structure of the hardware operating environment involved in the solution of the embodiment of the present invention.
[0053] In this embodiment of the present invention, the terminal is a battery control device.
[0054] Such as figure 1 As shown, the terminal may include: a processor 1001 , such as a CPU, a comm...

The invention discloses an energy storage control method, an energy storage system, and a computer storage medium. The maximum unit power of each battery is obtained according to the maximum power and rated capacity of each energy storage battery in a set of energy storage batteries in the energy storage system; The minimum value among multiple maximum unit powers; compare the minimum value with the average target power of the unit capacity of the energy storage battery set; when the minimum value is greater than or equal to the average target power of the unit capacity of the energy storage battery set, according to the unit capacity The average target power and the rated capacity of each energy storage battery adjust the power of each battery in the energy storage battery set, and the unit power of each energy storage battery is equal to the average target power of the unit capacity. The invention constructs a power loss function, the function has an upward concave shape in the coordinate system, the function value of the middle point is smaller than the function average value of the points on both sides, the power loss is the smallest, and the charging and discharging efficiency is higher according to the average target power per unit capacity.
Description
technical field [0001] The invention relates to the field of energy storage technology, in particular to energy storage charging and discharging technology, and in particular to an energy storage control method, an energy storage system and a computer storage medium. Background technique [0002] In the renewable energy power generation system, the energy storage system is combined with the power generation system (such as photovoltaic power generation, wind power generation, etc.), and the energy provided by the power generation system to the grid is reasonably adjusted through energy storage. When the power generation system generates excess electric energy, the energy storage system is used to store electric energy, and when the electric energy is insufficient or unstable, the energy storage is used for power supply or adjustment, so as to realize peak-shaving and valley-filling of electric energy supply, and improve the smoothness and stability of power supply.
