Research On Ancillary Service Under Electricity Market Environment

The competition market reform in electricity industry is a main trend in the world. The electricity market in China is just in the beginning. The structure of electricity industry, market model and operation mechanism are key problems in the market operating. How to realize the optimal configuration of resources on the basis of market measure, especially under the immature conditions, becomes the primary issue in the electricity market research at present. More and more researchers pay attention to The Ancillary Service (AS),which is an important part of the power market, Its Competition Strategy And Pricing problem have become a major concern.In this thesis, proceeding with the current status analysis of domestic and foreign electricity market experience, as well as the development of electricity industry in China, then, analyzing the part and feature of the ancillary service and Ancillary services pricing mechanisms and cost recovery mechanisms discussed and applied in the world are introduced, the necessary and worthy study of AGC(automatic generation control)in electricity market was pointed out. The study in this paper was focus on some issues about AGC service in electricity market. The research including:(1) Analyzing the cost of AGC units: According to the features of AGC ancillary services, a pragmatic method for caculating the AGC cost is put forward, this method can provide economic signals in deregulated environment.(2) The models of AGC units participating in electricity market: After analyzing systematically technical and economic characteristics of power industry, the model of electricity market and the subsistent models of AGC units participating in electricity market, basing on the current instance of power market innovation in china, this part proposed a new solution to the AGC units participating in electricity market in deregulated environment. The numerical example applies to a practical system indicates that the proposed method is valid and practical.(3) Discussion the Settlement and assessment of AGC units: To evaluate, examine the regulation efficiency of AGC units and give them economic compensations can promote the performance of AGC units.
