Research On Adaptability Of Distributed Photovoltaic Power Supply In Xingguo County

Energy is an important material basis for development and progress in all fields of society.With the rapid development of the society,the exploitation and consumption of fossil energy and the development of new energy sources such as photovoltaic are imperative.Photovoltaic power generation system consists of photovoltaic modules,inverters and accumulators,according to the scale and concentration can be divided into the centralized large-scale parallel grid photovoltaic system and the distributed small parallel photovoltaic system,which can be combined with the home building,convenient installation and small investment.In this thesis,focusing on photovoltaic power institute,found and network access of photovoltaic power under the condition of without affecting the normal operation of power grid has access to the largest scale,facing difficult to access,to improve this situation into account to ensure normal power quality viable economic and technological conditions,the need for rejuvenating distributed photovoltaic power given ability to conduct a comprehensive assessment of the analysis,and put forward optimization measures to improve the given and rejuvenating the country power grid photovoltaic power capacity.To institute in July 2017 access to 35 kv distribution network for photovoltaic power supply calculation template,plugged into a power supply of photovoltaic(pv)power fittings,synchronous record power flow data,explore in keeping the distribution network under the condition of relatively stable,the biggest photovoltaic(pv)power supply and distribution network can be given access to capacity.Distributed photovoltaic(pv)power supply and distribution network access to the optimization measures are put forward,were used to predict the output status of the distributed photovoltaic power,spot investigation phone APP development to improve the network data accuracy and expand the development of BPA flow,function module,promote efficiency of modeling analysis,build distributed power intelligent management platform to improve the efficiency of grid system is given and electricity resource scheduling ability.It is necessary for China to develop the photovoltaic industry.The state also strongly promotes the "photovoltaic poverty reduction" policy.In the future,distributed pv will have a sound development vision in China.
