Construction Of SG Power Grid Operation Economic Evaluation System And Operation Optimization

Since its market operation of China’s power industry, power systems for a number ofreforms, with the separation of grid and policy implementation, power grid Corporation as anindependent economic entity, it is an independent legal person representative need to beself-sufficient, need to change the operating mode. Era changed the economic operation ofpower network planning, and go-to-market. By price competition in the market to achieveregional allocation of power resources, which led to concern about the economic efficiency oftransmission. Through economic evaluation of transmission network operation, not only canunderstand the transmission grid overall operation status, you can also spot weaknesses in thegrid operation, very important for the planning and construction of power transmission andtransformation. Establishment of comprehensive evaluation model based on SG gridoperation economic analysis calculations.First of all, this article analyses the SG economy characteristics of the transmissionnetwork, and for all kinds of clues leads to the SG grid operations-related indicators.Hierarchical transmission losses, followed by classification grid load, grid reliability,dimensions, will integrate the various indicators categorized to establish a more rationaleconomic evaluation of transmission network operation system. Then, after a comprehensiveevaluation process, using analytic hierarchy process method for determining the index weightin this article, by establishing, calculating weight, consistency of a judgment matrix testprocedure to determine the weight of each indicator. After using fuzzy comprehensiveevaluation method based membership function model and parameter, a comprehensiveevaluation of2012and2009operating facts.Finally, by comparing2012with2009evaluation findings have identified importantfactor influencing the SG of transmission network operation economy. On this basis, in orderto raise SG grid optimization operation economy of proposed and2013that could issuepreventive measures.
