In the case of initially setting up a power supply price(PSP) mechanism which can promote the healthy development of power grids in the "Eleventh Five-Year" of the country,this paper has summarized relevant materials &introduced foreign practical experiences and analyzed PSP regulation mechanism from both sea and abroad,then, according to the actual problem of China,An improved price-cap model for effectively stimulate each power supply company(PSC) to increase its operational efficiency is presented.The new model overcomes the difficulty of defining preliminary regulated price and it is able to reflect actual price fluctuation of each PSC's investment.With the use of Data Envelopment Analysis(DEA) and Analytic Hierarchy Process(AHP), efficiency factor X can be found.Then,both power-grid's investment and power quality factors are taken into account for further exercising the model's incentive effects. Compared to the traditional model,the improved result and its example analysis show a stronger availability for regulating developing grid's PSP. |
