摘要
在传统指数型荷电状态(SOC)下垂控制策略基础上进行改进,提出一种变调节因子SOC下垂控制策略,通过在不同阶段改变调节因子n的值,在保证系统收敛性的前提下,提高功率响应速度,从而解决传统SOC下垂控制中功率响应速度和收敛速度的不可兼顾性问题。最后搭建由2台储能模块(ESM)构成的分布式储能仿真平台和实验平台,验证了所提出SOC下垂控制策略在功率均衡速度上的优势。
In this paper,the improvement is made based on traditional exponential state of charge(SOC)droop control strategy,and a variable adjustment factor SOC droop control strategy is proposed.By changing the value of the adjustment factor at different stages,on the premise of ensuring system convergence,the power response speed is increased,to the problem of incompatibility between power response speed and convergence speed in traditional SOC droop control is solved.Finally,the distributed energy storage simulation platform and experimental platform composed of two energy storage module(ESM)were built to verify the advantage of the proposed SOC droop control strategy in power balance speed.
