Power generation predictive control method for photovoltaic power station

The invention discloses a power generation predictive control method for a photovoltaic power station. The method comprises the following steps of: firstly, acquiring weather forecast data in a future time period; and secondly, combining the weather forecast data, current longitude and latitude data, the installed capacity of the photovoltaic power station and historical power generation data of the photovoltaic power station, and thus obtaining the power generation total quantity of the photovoltaic power station in the future time period. Therefore, the power generation quantity situation of some day can be judged, corresponding plan information and early warning information can be output by software, and power generation loss and equipment damage caused by weather change are avoided.
