Research On Bidding Strategies Of Generation And Distribution Companies' Based On Market Operating Mode

With the sustained rapid economic development, constantly advancing of industrial modernization and urbanization in China, the demand for electricity is growing fast. With the implementation of the policy of"separating the plant from the net and bidding the net", the reform of China's electric power industry entered a substantive stage, whose goal is to break the monopoly and bring competition and improve economic efficiency, and ultimately achieve the rational allocation of social resources and social maximum benefit. Thus, in the fierce competition of the electricity market, how to adopt an effective bidding strategy becomes an important problem to generation and distribution companies. Taking the actual situation of China's electric power industry into account, the thesis builds the bidding strategy model of generation and distribution companies', and studies the bidding strategy based on the models.Firstly, the thesis analyzes the present investigation situation on electricity bidding strategy and its relevant problems. Then the thesis develops a generation company's bidding strategy model based on the analysis of the market operating mode. With the help of the supply function model, the thesis simulates the generator's strategic behavior. According to the actual operation, the thesis assigns parameters and solves the model. At the same time, the thesis compares the on-grid electric price in fully disintegrated and partially vertical integrated operating mode using a comparative static approach. Thirdly, the thesis develops a supply company's bidding strategy model and solves the model based on the study of China's generation company's bidding strategy. In the model, the goal is to maximize the expected income of distribution companies. And, with the help of cost switching function, the thesis simulates the wholesalers'market share. Finally, the thesis gives some advice on the reform direction of China's electric market. The study enriches the methods of research on generation and distribution companies'bidding strategy, and has great significance in reforming China's electric market.
