储能电站动态交互作用及稳定性分析
Interactive Coupling and Stability Analysis of Energy Storage Power Station
摘要
Abstract
When multiple energy storage units are connected to an energy storage station by the power electronic converter,the interaction and coupling effect bring challenges to the stable operation of the system.The small-signal model of the parallel storage system was established.The stability analysis was carried out based on the dominant modes and participating factors of the system.According to the relationship between DC bus voltage and current,a new rule was found:when the load power was constant,the increase in the number of power stations will produce an impedance multiplier effect,which can improve the system stability margin.Moreover,the improved participation factor method was proposed to verify the regularity of the effect.Finally,the experimental results verify the correctness of the above analysis.关键词
