Photovoltaic power station aggregation modeling method based on parameter equivalence

The invention provides a photovoltaic power station aggregation modeling method based on parameter equivalence, and the method comprises the steps: determining the structure and total capacity of an aggregation equivalence model based on the internal structure of a photovoltaic power station and the capacity and structure of each photovoltaic power generation unit; equivalent parameter calculation is carried out on a photovoltaic module, an inverter, a machine end transformer, a current collection circuit and other parts, and an aggregation equivalent model of the photovoltaic power station is constructed. According to the method, the aggregation equivalence of the large-scale photovoltaic power station can be realized on the basis of remarkably reducing the complexity of the system, and the simulation calculation efficiency is greatly improved while the operation characteristics of the photovoltaic power station model and the precision of the aggregation model are reserved. 本发明提供一种基于参数等值的光伏电站聚合建模方法，包括：基于光伏电站
