基于一致性算法的分布式储能系统协同控制策略
Cooperative control strategy for distributed energy storage systems based on consensus algorithm
摘要
Abstract
In AC microgrids,energy storage systems operating in parallel frequently suffer from overcharge and over-discharge risks due to inconsistent state of charge(SOC)among energy storage units,as well as reactive power sharing imbalance caused by inverter parameter mismatches and line impedance differences,which degrade the stability of microgrids.To tackle these problems,a coordinated control strategy for virtual synchronous generators(VSGs)based on a fused consensus control algorithm is proposed.First,the hyperbolic tangent equalization coefficient with nested power exponents is dynamically coupled with the output active power reference,achieving rapid SOC equalization of different energy storage units under adaptive adjustment of output power.Then,based on SOC equalization,a coordinated reactive power-voltage control strategy is designed.By introducing adaptive virtual impedance based on real-time reactive power sharing deviations,the accuracy of reactive power sharing is improved,while a voltage compensation loop is added to suppress voltage sag.Finally,simulation and experimental results verify the effectiveness of the proposed strategy.关键词
