Research On Benefit's Comprehensive Evluation And Financing Mode For Ubran Power Newtork Cabling Reconsturction In Power Market

With steady and rapid development of economic in our country, urbanization is also accelerating,power newtork sturcutral problems are exposed gradually,and the growth of power distribution newtork can not satisfy electricity requirement. Uncoordinating between the overhead power lines and the urbanization progress on a large scale prompted reconstruction to city grid.Ubran Power network cabling reconsturction can boost up power supply ability and quality of our city grid,also can improve reliability of power supply and beautify circumstance of cities.But cabling reconsturction need to invest a lot of money,so it be of very practical significance and important theory research value to do research on benefit's comprehensive evluation and financing mode for ubran power newtork cabling reconsturction.In this paper,through analysis of the current condition of domestic and the benefit's in ubran power network cabling reconsturction,and research status of financing patters in cabling reconsturction, the advantages and the necessity of cabling reconsturction in city in power market is demonstrated.In the premise of considering the market factors, benefits internal and external bring by cabling reconsturction are analysed. In order to evaluate the benefit of ubran power network cabling reconsturction rationally,accurately and scientifically, the benefit comprehensive evluation indexes are divided into four parts: economic benefit,power grid benefit,social benefit and environmental benefit,then the cabling reconsturction comprehensive evaluation index system is established. The cabling reconsturction benefit's comprehensive evaluation model is established in this paper based on particle swarm algorithm and the back-propagation algorithm neural network. Through the benefit's comprehensive evaluation for cabling reconsturction in shijiazhuang Hebei province, it is demonstrated that power grid enterprises, power users as well as the whole society will get profitable after ubran power network cabling reconsturction.Financing modes of cabling reconsturction in power market conditions is discussed, and new methods are puts forward to solve the problem of financing difficulties for grid enterprise in cabling reconsturction.Hope to provide some reference for cities which cabling reconsturction will be carried out.
