A Study Of Generator' Bidding Strategy And Market Power In Generation Market

Abstract: Market power is typically defined as the ability to be profitable greater than that of equitable competition alone or jointly with others, or raise market price above competitive level. Market power potential is a major concern in design, planning, operations and control of electricity markets, harming market competitiveness and efficiency in generation production, service quality, technology renovation and environmental protection. Research on market power has great importance because market power affects the realization of justice and impartiality of power market by fortune transfer from purchaser to bargainer. This paper focuses on the preventing, implementation and monitoring of market power, resulting in the following innovating fruits.Firstly, this paper establishes the basic flow of bidding for generator, which contains inner and exterior environment analysis, bidding strategy selection and actualizing, and learning afterwards. Based on the flow, this paper puts forward various bidding strategies (models and algorithms) for generator, which are respectively based on cost decomposing and callback, expected profit, competitor forecasting and integrated self market power index. The details are as follows.1) Cost decomposing and callback based method decomposes the total cost of generator into active power and reactive power concerned parts separately, then apportions the former part that is callback through main energy market by a great deal...
