The Coordination Control Strategy of Clustering PCS and Its Application

As the “carbon peak,” “carbon neutral,” “building energy market and data market” have been put forward, the power grid needs to accept a greater challenge. It is necessary to control the energy storage system with PCS (Power Conversion System) because of the frequent occurrence of explosions due to the problems of energy storage power station. This chapter proposes a new energy storage controller, and uses the linear optimization algorithms of primary frequency modulation, constant active power control, dynamic reactive power voltage regulation, constant power factor voltage regulation, and constant reactive power voltage regulation to design the corresponding functions. Therefore, the safety and economic aspects of energy storage urgently could be resolved. So, the chapter introduces a novel controller based on PCS control algorithm to carry out certain functions, to meet the requirements of the grid.
