By the end of 2002 China's power industry practice \Currently, the National Development and Reform Commission is leading the development deepen tariff reform program, its long-term goal is to really establish a market-oriented pricing mechanism. Node pricing methods currently implemented in the East China region, with remarkable results. When conditions are ripe, the node pricing will dominate China's power market. In taking node pricing, China's power market structure will be taken to be more conducive to the goal of market power industry, power transmission industry expansion process should be taken to incentives will be more effective. This article is based and launched in order for the power industry market-oriented reform proposals. Respectively, from the traditional paper-based control mechanisms and market-based mechanisms the two aspects of the transmission network expansion incentive industry issues were discussed analysis mode selection. Based control mechanism, the paper first consider the three-node network structure for the expansion problem. As the Government of the company's cost type is not very clear, and therefore into the case of complete information and asymmetric information be considered in the case of two scenarios; Meanwhile, in the three-node network structure, the participating companies have two network expansion, the company's collusion between the problem must also be considered. In this paper, four cases were established for this mathematical programming model solution results from the comparison we found that, when there is collusion between the companies problems, will lead to an overall decline in the total social welfare, for which we should minimize collusion between companies probability, for example, can be appropriately increased cost sharing between the companies. Secondly, the structure of the three-node network extends to verify accuracy of the conclusions. In a market-based mechanism, the first of a three-node network structure of the transmission network expansion investment issues studied; Secondly, the three-node network structure vertically integrated transmission network expansion mode excitation problem is studied. The purpose of this paper is to compare two modes through solving the model results, and then come to what mode is better. Solving the model results contrast we found that in taking the node pricing, China's power transmission network expansion to take the market mechanism is superior to the traditional control mechanisms. If you take the market mechanism and the transmission network companies can get FTR payments, will not necessarily give the expansion of the transmission network capacity to bring greater downward distortion. Through case studies on the grid, East China Grid Company online transaction flows between provinces there is great potential for development, and the traditional model of its electric power and energy control mechanism flow is highly restricted, the market mechanism model is conducive to energy resources rationalization of distribution. By comparing model results and case analysis, we can get to take the market mechanism model is more suitable for the expansion of power transmission industry, can further improve the efficiency of power transmission industry market. Through the transmission network expansion analysis of the situation on the grid to take control mechanisms hinder investment and construction produce more, and take the market mechanism can be extended financing channels to attract more investors.
