Prediction Of The Output Of Guodian Inner Mongolia Chayouqianqi Photovoltaic Power Plant

The output electricity of photovoltaic power station is determined by three factors: the installed capacity, peak hours and performance ratio of the grid photovoltaic power station. When the installed capacity of photovoltaic power plant, the project site is determined, it is mainly determined by the following two factors. On the one hand, to rely on accurate solar energy resource data, select the scientific method, calculate the peak hours of the project; on the other hand, according to the actual situation of the power plant and the experience of the previous data, the system efficiency of the project is calculated. Accurate prediction of the output of photovoltaic power station is carried out by the accurate control of the peak hours and the system efficiency.In this paper, "the actual situation of Inner Mongolia Chayouqian banner area of a 50 MWp photovoltaic power plant" as the basis. Firstly, through the analysis of the actual acquisition of the solar energy resource data, the radiation quantity of the optimum dip angle is selected, and then the overall system efficiency is obtained. Finally, the prediction of the PV power station is carried out. Finally, the theoretical predictions and the actual operating conditions are compared.
