Description

Technical field [0001] The invention relates to the technical field of photovoltaic power generation and distribution, in particular to a controllable model and prediction method of a photovoltaic charging station. Background technique [0002] In recent years, with the increasing demand for renewable energy, solar photovoltaic power generation technology has been rapidly developed, and the application of large-scale photovoltaic power generation systems has become increasingly widespread, but many problems have also emerged. In the energy systems of communication, business and civil use, photovoltaic modules have become a practical renewable power source. The plug-in power or hybrid cars on the market as a new technology have reduced carbon emissions and improved energy efficiency. Photovoltaic modules and plug-in hybrid vehicles are used as energy sources and energy storage components, respectively, and are connected to the grid. [0003] Since solar radiation is closely relate...
