Abstract

The invention discloses an energy storage system and an energy storage system control method, and the energy storage system comprises: a transformer, wherein one end of the transformer is connected with a power grid bus, and the other end of the transformer forms a common connection point; a detection trigger circuit, wherein the detection end of the detection trigger circuit is connected with thecommon connection point, and the detection trigger circuit is used for collecting electric parameters of the common connection point and outputting standby trigger signals when it is determined thatthe energy storage system is overloaded or flows reversely according to the electric parameters; and an energy storage converter, wherein the alternating current side of the energy storage converter is connected with the other end of the transformer, and the energy storage converter is used for sealing wave and waiting for a first preset time when receiving the standby trigger signal. According tothe invention, the protection response speed, safety and reliability of the energy storage system are improved.

Description

technical field [0001] The invention relates to the field of energy storage technology, in particular to an energy storage system and a control method for the energy storage system. Background technique [0002] In recent years, with the rapid development of battery technology, the use of energy storage system for peak regulation and frequency regulation is one of the effective means to solve the contradiction between power supply and demand. The energy storage system based on electrochemical energy storage technology can provide peak shaving and valley filling, demand management, Multiple services such as standby, black start, and demand response support are important means to improve the flexibility, economy, and security of traditional power systems. They can promote power balance, significantly increase the level of renewable energy consumption, and support distributed power and Microgrid is a key technology to promote the replacement of main energy from fossil energy to...
