基于多储能动态调控的光储黑启动控制策略

SOLAR STORAGE BLACK START CONTROL STRATEGY BASED ON MULTI-STORGE DYNAMIC REGULATION

首先,建立多储能光伏联合系统,根据储能实时状态将储能系统进行分级,设计3种不同优先等级的储能分别承担不同任务;然后,将不同优先等级的储能设定相应的控制方案,提出基于多储能动态调控的光储黑启动控制策略,实时监控储能的运行状态,以防止多储能系统因越限等原因造成黑启动任务失败;最后,通过Matlab对3种不同工况进行仿真模拟,验证多储能动态调控的黑启动控制策略的有效性。

Black start of power system means that after the whole system is shut down due to fault,without relying on the help of other networks,the whole power system is finally restored through the starting of the units with self-starting capability in the system.With the rapid development of new energy sources,it also brings challenges to the stable operation of the power system,and it is more important to develop a black start plan in advance.With the continuous development of photovoltaic and energy storage systems,and the fact that energy storage systems can compensate for the randomness and volatility of photovoltaic power output,the combined optical storage system has become a new choice to undertake the task of black start.This paper firstly establishes a multi-storage PV joint system,classifies the energy storage system according to the real-time state of energy storage,designs three different priority levels of energy storage to undertake different tasks;sets the corresponding control scheme for different priority levels of energy storage,proposes a light storage black start control strategy based on multi-storage dynamic regulation,monitors the operation state of energy storage in real time,prevents the multi-storage system from black start caused by overrunning limits and other reasons Finally,the effectiveness of the multi-storage dynamic regulation black-start control strategy is verified by simulating three different working conditions through Matlab simulation software.
