Machanism And Method Of The Voltage-grade Transmission And Distribution Price

To open up markets, electric power reform determine further big deal direct purchase of electricity by the use, Countries should further break the monopoly state-owned enterprises. Large user of direct power purchase transaction smoothly needs the independent distribution of electricity, but at present our country has not yet formed an independent distribution of electricity. Because of the different voltage levels and transmission and distribution assets, users should share the different costs. Therefore, the price of transmission and distribution service which each user should pay is different.At present, transmission and distribution grid in China is still under the monopoly. The difficulties of China’s electric power system reform are determined. It’s important to establish the transmission and distribution price system. The government definited that the price is range from important public utility, public welfare service and natural monopoly of the network.So this topic research points voltage grade distribution electricity price calculation model and method. Paper discusses the basic principle and establishment method of the electricity pricing in our country, transmission and distribution cost and its components are analyzed, Research is mainly focused on the long-term marginal cost of power transmission and distribution calculation method. Based on the theory of marginal cost pricing, the cost of the fixed cost and the network loss in transmission and distribution business, put forward the suitable for our country’s electric power transmission and distribution points voltage grade fixed costs and loss allocation method, set up points of voltage grade distribution electricity pricing method. Finally, numerical examples verify its rationality.
