Research On Bidding Strategy Of Power Generation Enterprise Under Energy-saving Electricity Market

Along with the deepening of the power market-oriented reforms in China and the promotion of energy saving and pollutant reduction in generation field,power generation enterprises not only deal with the external competition environment,but also improve the defaults of management mechanism under the traditional system. Therefore,the further research on cost management,market price forecasting and bidding strategies for power generation enterprises has been the necessary work to better participate in market competition.This paper includes three parts.Firstly,the paper redefines the concept of external costs combined with current status of cost management in generation enterprises.And on basis of it,it puts forth the fixed cost allocation based on annual contract generation decomposition.Then,based on research of the existing time-series and neural network forecasting method,the paper proposes integrated ARIMA and GARCH with confidence interval electricity price forecasting method and based on wavelet analysis neural network electricity price forecasting method. Finally,the paper gives time-sharing bidding strategy based on MCP.At the same time,taking into account of energy saving and pollutant reduction,it discusses coping strategies of power generation enterprises in the three possible market modes.
