Reported on November 24, by ningxia electric power company to assume the state grid corporation of key research topics - — Large-scale grid-connected photovoltaic (pv) run smoothly passed the experts acceptance, pilot project in grid-connected photovoltaic field shows the ningxia company scientific research strength at the same time, the project also for ningxia 2 million kilowatts of light energy during the 'twelfth five-year' large-scale grid provides strong technical support. < P> according to the understanding, out of my country is rich in solar energy resources in ningxia region, the district average solar radiation from 4950 to 6. 1 billion kilojoules per square metre. Good natural conditions and relatively well in ningxia grid access ring, attracted by huadian, guodian CLP vote and other large power generation groups and inside and outside the region some energy companies are rushing in ningxia wind power market. Data show that by the end of 2012, ningxia wind power grid photovoltaic power capacity will reach 29. 3 kw, is expected to reach 1 million mw in 2015, the vision of the installed capacity of 2 million kw or more. < / P> < P> strong pace of leap-forward development for photovoltaic overwhelming, but how to overcome the uncertainty of photovoltaic itself, let photovoltaics can particles belong to the warehouse, at the same time solve the grid-connected photovoltaic (pv) bring enormous pressure to the power grid security and stability, become an important subject to be solved of the grid. < / P> < P> in January this year, SGC formal project research large-scale photovoltaic (pv) grid operation project, ningxia company, which is based on high technology research and development ability, positive expressed the project demands, eventually with qinghai, Tibet, the company has been selected for the project pilot units, the company mainly to undertake photovoltaic power plant in ningxia forecast, operation monitoring, operation control aspects of the research work. < / P> < P> in less than a year, ningxia company in conjunction with the China electric institute, its electric related research institute of scientific research strength, the photovoltaic power station has been the interconnection of east ningxia access power station as a pilot project, through pilot plant to carry out the research on photovoltaic power generation and coordinated operation of ningxia electric grid. The project through research, cloud cover, temperature, solar radiation strength space-time location, photovoltaic panels and other factors influence on the output power, based on numerical weather prediction of all-weather, time and space scales of photovoltaic power station power prediction model, realize the coordinated control of a variety of interconnected power grid reactive power sources. Be worth what carry is, researchers also introduces the artificial neural network and meteorological elements of statistical prediction method and so on many international frontier research subjects and auxiliary project development, makes the project created a number of its first: the first built photovoltaic power station at the provincial level short-term power prediction system, which can realize the future 0 to 4 hours of super short-term power prediction; First comb and implement all the photovoltaic power station operation network information monitoring, realize the data real-time acquisition; In the end, the ningxia electric power company with high honors to the SGC made a satisfactory answer. < / P>
