Photovoltaic power station generating capacity calculation method and server

The invention provides a photovoltaic power station generating capacity calculation method and a server, and is applied to the technical field of photovoltaic power generation. According to the invention, the method comprises the steps: dividing actual photovoltaic power station generating capacity calculation of a target power station into two parts, obtaining time series data of preset meteorological parameters of a target power station in a specified time period, and then calculating time series data of theoretical generated power of the target power station based on a system physical model; meanwhile, calculating the time series data of the power generation loss of the target power station based on the loss model; and finally, performing calculating according to the time sequence dataof the theoretical generated power and the time sequence data of the generation loss of the target power station to obtain the estimated generating capacity of the target power station in the specified time period.
