The invention relates to the field of power grids, and particularly relates to an inverter parameter control method. In allusion to a characteristic that randomness in photovoltaic power generation output and load fluctuation in a microgrid results in dynamic changes in operation mode of the microgrid, output and load of a photovoltaic power generation system are described by using a dynamic probability model of a random variable, and thus a microgrid inverter parameter optimization method considering multiple operating modes of the system is researched. The inverter parameter control method takes the operation randomness and the operation mode diversity of the microgrid into consideration, and carries out optimization on parameters of a microgrid controller from an overall perspective based on dynamic probability characteristic root analysis. 本发明涉及电网领域，尤其涉及种逆变器参数控制方法。本发明针对微电网中光伏发电出力及负荷波动具有的随机性会造成微电网运行方式动态变化这特点，利用随机量的动态概率模型来描述光伏发电系统出力与负荷，并进而研究考虑系统多运行方式的微电网逆变器参数的优化方法。本方法考虑了微电网的运行随机性和运行方式多样性，基于动态概率特征根分析，从整体角度出发
