Distributed photovoltaic power station comprehensive effect evaluation method, system, equipment and medium

The invention discloses a distributed photovoltaic power station comprehensive effect evaluation method, and relates to the technical field of photovoltaic power generation. The method comprises the steps of collecting first power generation information and weather information of a power station in a first time interval, wherein the first time interval is larger than a preset time threshold value; according to the first power generation information and the weather information, obtaining a theoretical power generation amount of the power station in a second time interval through a power generation amount prediction model; and determining the power station income of the power station in the second time interval according to the theoretical generating capacity, the electricity price and the subsidy of the unit electric quantity. The power generation information and the weather information of the power station in a long time period are collected, then the power generation amount of the power station is predicted
