Study On The Model Of Wind Power Participation In Short-term Power Transaction Under The Electricity Market Transition Period

With the rapid development of wind power industry in China,the plan can not meet the grid demand of the wind power e-commerce.At present,our country is undergoing a market-oriented reform,the market of accommodating wind has become another important way of wind power online.Meanwhile,with the maturity and breakthroughs of wind energy technology,generation costs and government subsidies are becoming less and less.However,due to the intermittency,volatility and inaccuracy of the wind power output power,wind power has a disadvantage in the power market competition.At present,our country is planning to start the spot market.Therefore,it is of theoretical and practical significance to study the short and medium term electricity market transaction mode in the transition period of electricity market reform.The contents of this paper include the following three parts:First,we have investigated the mature electricity market mode and the wind power Internet transaction mode abroad,compared and analyzed the advantages and disadvantages of each country's wind power Internet mode,which is of reference significance for the development of wind power in China.Change the investigation and analysis of power market reform is an important stage and wind power consumptive way,to prepare for the next style in electricity markets model.Secondly,this paper makes a detailed study on the mode of wind power participating in the monthly electricity market.This paper gives the monthly market trading mode which is suitable for the transition stage of China's electricity market,and points out that the price difference-electricity price quotation system is more advantageous.According to the existing policy support,the monthly market mode of wind power participating in the flexible plan and market combination is put forward,and the feasibility and superiority of the model are demonstrated.Finally,after the analysis of necessity and limitations of the monthly electricity market before the market,this article has conducted the research to the wind power mode and strategy to participate in the day before the short-term market.According to the prediction of wind power output and the actual output of the historical data,fitting the probability density function of wind power output,and on the basis of the function obtained expected profit function in the day before the market for wind power,the decision in the days before the Declaration on the market of wind power.
