Cost Pricing Analysis Of Transmission Loss Based On Cost Conservation Principle

The current price calculation method mainly uses the marginal cost method, but it is difficult to accept that putting products, output and cost as the independent premise of the transmission cost, as well as using them in the computing the inter-coupling power systems. There are many factors that is able to affect the transmission costs, while network loss is the only one that cannot be drawn from the one caused by financial checking methods. This paper starts from physical tracking of net power and the concept of cost of conservation, proposing the transmission costs model which considers the network loss only. Then discuss the concept of cost of conservation deeply, describing the analytical relationship of the costs of injection, transmission loss and load outflow costs, and pointing out that this model satisfies the net balance of the costs and profits. Then put forward the method of user costs price based on the principal of same network, same quality and same price. The method is able to express the costs concerning the costs of all costs of the network. At last, the computational result on power system of IEEE 3 generators and 9 nodes proves that the method presented in this paper is accurate enough and available in the practical applications on transmission costs of real electric power system.
