Prediction Technology of Photovoltaic Power in Sandstorm Weather Based on Upstream and Downstream Coordination

Based on the influence of sand and dust storms on upstream PV stations, a sand and dust storm photovoltaic output impact model is constructed. Considering the dynamic characteristics of sandstorms, a geographically located model for the evolution and attenuation of sandstorms in upstream and downstream photovoltaic power plants is constructed. Based on the evolution model of upstream and downstream sandstorms and the impact model of sandstorms on photovoltaic output, a photovoltaic output prediction model for downstream photovoltaic power stations during sandstorms is constructed. Based on the similarity characteristics of output between distributed PV power stations and centralized PV power stations, a distributed photovoltaic sandstorm output prediction model is established to acquire the output prediction of photovoltaic sandstorms in a certain area.
