Research On The Transmission Pricing Of Direct Power-Purchase Pattern For Large Consumer In Power Market

The pattern of direct power supply for large customer is the inevitable tendency ofelectricity industry reformation in China, price problem is the focus of differentparticipator. Accordingly, transmission pricing of direct power supply for largercustomer, has become the key of the reform of direct power supply for large customer .The transmission grids in developing countries are weak, and the structure of many gridsis not reasonable,So the problem of capacity resource restriction of grid in developingcountries is more serious than developed countries. Therefore, the transmission pricein developing countries need reflect sufficient economy information and promote to usenetwork resource fairly and reasonably. Nowadays, because of the limitation of thetechnical condition in China , marginal cost pricing method is improper, this paperproposes to adopt two-part electricity pricing for transmission pricing of direct powersupply for large customer, transmission price is divide into the fixed cost and thevolatile cost. A new method for transmission pricing of larger customer in power marketis presented based on Shapley-value of games theory. The validity and feasibility of themethod are illustrated by specific examples.
