Abstract

The invention discloses an energy storage power station operation control method and system considering battery life. The method comprises: obtaining parameter data of a fast charging station area containing energy storage; determining peak clipping power and valley filling power of the energy storage power station according to the parameter data of the fast charging station area containing energystorage; according to the parameter data of the energy storage-containing fast charging station area, determining an operation control objective function of an energy storage-containing fast chargingstation area energy storage power station considering the service life of a battery; determining charging and discharging target power of the energy storage power station through a genetic algorithm;and determining the optimal charging and discharging power of the energy storage power station through a preset control strategy. According to the invention, the energy storage power station participates in peak clipping and valley filling control of the quick charging station area containing energy storage and improves the economic benefit of the quick charging station area containing energy storage, the service life of the battery is considered, the discharge depth of the energy storage battery is controlled within a reasonable range, the purpose of delaying the attenuation of the service life of the battery is achieved, and the regional economy of the quick charging station containing energy storage is improved.

Description

technical field [0001] The present invention relates to the field of energy storage and new energy, and more specifically, relates to an operation control method and system of an energy storage power station in a fast charging station area including energy storage considering battery life. Background technique [0002] The fast charging station area including energy storage mainly refers to the charging (including fast charging or fast / slow charging hybrid) storage station area, solar storage charging (including fast charging or fast / slow charging hybrid) power station area, etc. In recent years, the number and scale of fast charging station areas with energy storage in cities have been expanding. With the acceleration of urbanization in my country, fast charging station areas with energy storage have become one of the symbols of "smart cities". As a symbol of the city, the fast charging station area with energy storage has an increasing energy demand, and the load also pre...
