The invention provides an energy storage system cooperative control method, device and equipment and a storage medium. The method comprises the steps of comprehensively evaluating the operation condition of each subsystem based on each static evaluation index and each dynamic operation index of each subsystem in an energy storage system, and generating a power control instruction of each subsystem in real time according to the comprehensive operation condition, and realizing cooperative control of the large-capacity and high-safety energy storage system, according to the weight and the numerical value of each static evaluation index of each subsystem, calculating to obtain a static evaluation index evaluation result of each subsystem, obtaining a dynamic operation index evaluation result of each subsystem according to each dynamic operation index of each subsystem and the numerical value of the weight, calculating a static evaluation index evaluation result and a dynamic operation index evaluation result of each subsystem to obtain a comprehensive index evaluation result of each subsystem, and obtaining a power instruction of each subsystem through integrating the index evaluation result and the total power instruction for cooperatively controlling each subsystem. Economic, safe and technical factors of the battery energy storage system can be comprehensively considered, power instructions of all subsystems are generated, and cooperative control of the energy storage system with large capacity and high safety is achieved.
Description
technical field [0001] The present invention relates to the technical field of design collaborative control, and specifically relates to a method, device, equipment and storage medium for collaborative control of an energy storage system. Background technique [0002] As an effective measure to improve the ability of the power system to accommodate large-scale new energy generation, battery energy storage technology has always been a research hotspot. With the gradual increase in the penetration rate of new energy power generation in the power grid, the capacity of energy storage systems has gradually developed from the kilowatt-hour level in the past to hundreds of megawatt-hours or even gigawatt-hours in recent years. [0003] According to the current level of power devices, the power of a single energy storage subsystem is generally 500kW to 2MW. Therefore, large-capacity energy storage power stations or energy storage systems are often composed of multiple energy storag...
