The Research Of Photovoltaic Power Prediction

With today’s increasing depletion of traditional fossil energy sources, scientistsput a great effort to study and explore new energy sources. The use of photovoltaicpower generation is one of the key research directions.Faced with different capacities, different grid, different system configurations ofphotovoltaic power generation system access to the transmission grid or distributionnetwork of different requirements from the grid perspective, the photovoltaic powergeneration characteristics different from the conventional power generation,conventional power plant conditions and access network technology and method ofcalculation is no longer applicable, plus there are not comprehensive, clear, operationalmanagement standards and technical specifications, it is difficult from the power gridenterprises quality, reliability, security, and standard management perspective on thephotovoltaic system to conduct a comprehensive assessment, resulting in a photovoltaicsystem and network complexity and difficulty.Distributed as an important power, solar photovoltaic power generation isincreasingly towards large scale from a standalone system and network direction. As thesolar PV power plant is the intermittent power supply, in the process of large-scale gridstructure and distribution system will run, etc. have a significant impact.Then the direct use of photovoltaic power generation, power generation verymuch influenced by the weather, will have a generating capacity of the fluctuations. Ifthe environmental parameters through the acquisition, expected for grid-connected solarpower plants over the short-term or short-term forecasts to quantify the amount ofpower, photovoltaic power generation industry will have a profound effect.This following literature is based on the real data of a photovoltaic power plant,after analysis of large amounts of data on short-term prediction of photovoltaic powergeneration with an initial understanding.
