Abstract


It does not have reached a conclusion that what measures should be adopted to ensure the planning and investment of long-term transmission grid expansion project in the electricity power market environment to achieve the optimal expansion planning and investment objective of the entire power system. This paper analyzes three methods of transmission grid expansion investment in the electricity power market environment—long-term financial transmission right method, incentive regulation method and market power method, and then compares their characteristics and practicability. Long-term financial transmission right method is realizing transmission grid optimal expansion investment through organizing long-term financial transmission right auction by an independent system operator. Incentive regulation method is encouraging Transmission Company to invest transmission grid expansion through making Transmission Company undertakes the entire social cost of power transmission network congestion. Market power method is determining the transmission grid optimal expansion planning and investment project according to the action that the power producer can manipulate the market in electricity power market. This text analyzes the advantages and disadvantages of each of these three methods. Studies the theory,methods and related issues of transmission grid optimal expansion investment in electricity power market environment of our nation according to the reality of our country.This paper studies which kind of electricity power market structure and power network deployment management system can abstract the investment of transmission grid expansion better in electricity power market environment. Meanwhile, this text studies the policies and regulations factors of impacting network enterprise market position, transmission grid expansion funding sources, and price mechanism, and then with the reality of our country, provides police proposals which suit our nation’s electric power industry reform practice. The paper also explores the relationshipbetween power supply and network planning in electricity power market environment, provides the coordinating relation proposals between power supply and network planning.This text researches transmission grid expansion method which bases on long-term financial transmission right, and brings forward specific operating plans. Based on utility economics, this expansion method allows the investors of transmission network to bear the negative external influences which are produced by transmission grid expansion. To ensure transmission grid expansion is feasible, the investors of transmission network must buy adequate transmission rights from other transmission right-holders or power network deployment organizations must hold some adequate transmission rights when long-term transmission right is auctioned, to ensure that the expansion of transmission grid will not harm the original (or other) transmission right owners’interests.This text also researches how to guide the effective expansion of transmission grid by implementing the measures of incentive regulation in electricity power market environment. From the theoretical and practical aspects, the paper provides how to implement benchmarking or based on the price cap regulation model to the Transmission Company when the Transmission Company owns and operates transmission grid, and to encourage it to carry out transmission grid expansion to avoid transmission congestion.This paper studies how to determine the transmission grid optimal expansion planning and investment project according to the action that the power producer can manipulate the market in electricity power market. That is by analyzing and researching the structure of the power generation market to determine the optical expansion of transmission grid. And according to this analysis, the paper determines a joint probability distribution of power generation and transmission to calculate the net present value of investment projects in transmission grid expansion. Meanwhile, the paper proposes a new transmission congestion management approach to curb market power which can ensure fair and open network to all users of the transmission grid, and a fair price for transmission pricing.According to the above theoretical research results, this paper studies network optimization problem of the overall size based on the practical situation of a certain province transmission grid expansion investment, and gives the methods of confirming network overall investment through analyzing of numerous factors that affect network investment. Meanwhile, designs the concrete executive plan proposals and the effect of investment evaluation assessment methods of network investment optimization combines the network condition of this province. To enhance the maneuverability of assessment, exploit the corresponding aid decision support system according to the theoretical study.The results show that under the circumstances that generation and grid companies become an independent economic entity, use reasonable manners to expand transmission grid, enhance market operating efficiency through objectively and thoroughly studying on the theory and application of transmission grid expansion programming method after the separation of grid and generation, can achieve optimal economic effect. This paper’s research has important theoretical research meaning and actual using value to the electric system reform.
