Abstract: In the research of electricity market, electricity pricing is a key issue. Transmission pricing affects the interests of generation company, transmission company and consumer. In this paper, a new method of transmission pricing is proposed .It is based on the short term marginal cost method and further considers capacity cost. Simulation results show that the method proposed can not only lead to short-run market efficiency by providing effective economic signals to generators and consumers, but also ensure the balance between income and expenditure of transmission companies as well as help them accumulate special fund for transmission network expansion.

Abstract: This paper analyses several common transmission pricing methods of marginal cost and embedded cost deeply. It analyses pricing models of several transmission pricing methods, long-run marginal cost (LRMC) method, MW-Mile method, sensitivity method, flow tracing method, contract path method and stamp method. It also gives a comprehensive comparison of characteristics and limitations of these pricing methods, discusses their applicable conditions in aspects of fairness, economic, financial balance, transparency, operability and others, and makes a quantitative research of comparison based on a case, and verifies the results.

Abstract: The rapid development of national economy has brought serious environmental pollution problems. The issue of emission reduction has become one of the most important missions in China. As one of the largest sources of energy consumption and pollution emission, the power generation industry plays an important role in the problem of emission reduction. According to Chinese actual conditions, this study takes into account the inter-regional difference between the tasks of environmental emission reduction and the corresponding costs due to various factors, and proposes an inter-regional power-generation economic exchange analysis model under environmental constraints. The model integrates the environmental constraints, as well as the transmission costs and transmission lines constraints, and provides the results of optimal exchange combinations. The analysis of an example indicates that the inter-regional economic power exchange can maximize inter-regional advantages and minimize the costs of economic dispatch, which requires a sound transmission system and transmission pricing system.
