Method for predicting photovoltaic generating capacity in regional power grid

The invention relates to a method for predicting photovoltaic power generation capacity in a regional power grid, which comprises the following steps of: defining photovoltaic power generation equipment which has a direct interaction relationship with a dispatching command center in a regional power grid region as a base station, and defining other photovoltaic power generation equipment except the base station in the regional power grid region as scattered photovoltaic power generation equipment; a regional power grid area is divided into a plurality of base station units, and the sum of all the base station units covers the whole regional power grid area; each base station unit is composed of a base station and a prediction unit. The method can provide data support for electric quantity process balance regulation and control in dispatching command, and can be widely applied to the field of photovoltaic generating capacity prediction. 本发明涉及一种地区电网内光伏发电量预测方法，将地区电网区域内和调度指挥中心有直接交互关系的各光伏发电设备义为基站，将地区电网区域内除基站外的其余光伏
