Abstract

The invention provides an energy storage system based on SOC management, and a control method thereof. The control method comprises: obtaining the demand management target power and the peak load shifting target power of an energy storage system; judging whether the SOC of the energy storage system is greater than a preset demand standby power threshold value; if the SOC of the energy storage system is greater than the preset demand standby power threshold value, determining the target power instruction of the energy storage system by using the peak load shifting target power as a criterion when the demand management target power requires the energy storage system to charge or standby or by using one target power with deep discharging requirement of the two target powers as a criterion when the demand management target power requires the energy storage system to discharge; and if the SOC of the energy storage system is less than or equal to the preset demand standby power threshold, determining the target power instruction of the energy storage system, and controlling the energy storage system to execute corresponding action according to the target power instruction of the energy storage system, such that the economy of the energy storage system is improved.

Description

technical field [0001] The invention belongs to the technical field of power grids, and more specifically relates to an energy storage system based on SOC management and a control method thereof. Background technique [0002] With the continuous development of technologies such as batteries, inverters, and micro-grids, power field service operations based on energy storage systems have emerged. At present, the main applications of power field services are peak shaving, demand management, and frequency regulation. [0003] For the synergistic effect of peak shaving and valley filling and demand management, the existing scheme in the prior art is: when the current time reaches the peak electricity price period and the peace electricity price period, obtain the current PCC (Point of Common Coupling, public connection) point from the electric meter Actual used power; when the actual used power is less than the preset reported demand power, it will be discharged according to the ...
