Research on Monthly Balance Mechanism of Market-oriented Power Purchase Based on the Agency Mode
With the continuous promotion of China's electri-city market-oriented reform,the on-grid price of coal-fired power generation is formed by the market,and the power grid companies organize power purchase as the agency,which indic-ates that the market-oriented reform has entered a new stage.In provinces that do not actually operate the spot market,due to the cancellation of the base electricity,the power market lacks a supplementary mechanism to deal with the monthly deviation electricity.In this paper,the electricity composition of medium and long term power generation and the consumption is ana-lyzed based on the situation that the power gird companies or-ganize power purchase as the agency.Then the causes of medi-um and long term monthly.electricity deviation is given.A mar-ket equilibrium model and three monthly balance mechanisms are proposed.An example simulation of a provincial power grid in East China is given to analyze their characteristics and adapt-ability.Finally,corresponding suggestions are put forward for China's market design based on analysis of problems and de-velopment needs.
