| The Chinese electric power industry has reformed since 20 centuries 80's, developing the perpendicular integral mode of original electric power to open generating electricity and forming the generating electricity market. Now transporting electricity will be opened gradually and selling electricity must be opened at last to form selling market. With the mode of selling market opened, the paper gave a completely analysis and study about buying and selling electric power.The paper firstly learned from some abort representative operating modes and characteristics in electric power market, and gave the "four segments" operating modes of Chinese power market in future combing actual circumstance in Chinese electric power. Then the paper study about power load forecasting buying power electricity included estimating the electricity capacity and the study about selling power electricity included pricing and selling strategy.The electric power sale enterprise's power load forecasting that this paper has used a Yuan linear regression forecast law, the second-order auto-adapted coefficient forecast law and the gray forecast law. And programmed with VB to the load forecast has carried on the empirical analysisThe electricity purchasing combination to analyze the different market risk, had considered bought the electricity expense to be smallest and under the risk condition buys the electricity combination.The electricity selling combination in the analysis electricity price influence essential factor and in the electricity price formulation method foundation, based on the electric power product's substitution effect and the elasticity of demand analysis, has established the proper attention to both power supply enterprise and the user benefit electricity price fixed price model.The ultimate analysis the power load forecasting, the electricity purchasing combination and the electricity selling combination mutual influence relations. |
