构网型储能与九开关UPQC联合控制提升风电系统稳定性

open access: yesGaoya dianqi
针对高比例风电并网背景下,构网型直驱风电机组存在功率输出波动大、主动支撑能力不足、调频调压参与度有限等问题,提出一种构网型储能与九开关统一电能质量调节器相结合的新型拓扑与协调控制策略。首先,构建了该拓扑下的完整数学模型,并提出构网型储能基于虚拟同步机机制的有功调节与惯性支撑控制方法;其次,通过构建协调控制框架,实现储能系统与UPQC在扰动下的动态响应互补,以提升系统整体的频率稳定性与电压支撑能力;最后,在MATLAB/Simulink中搭建系统模型并设置了风功率波动、频率扰动和严重电压跌落3类典型工况 ...
