Study on Carbon Emission Trading Optimal Economic Efficiency of Power System under Different Auction Proportion

Carbon emission allocation method and mechanism of power system are analyzed firstly.The initial emission quota of each thermal unit is obtained under different auction proportion,and the emission trading economic efficiency of each unit is studied.To minimize the extra generation cost,an emission trading optimal economic efficiency model of power system based on carbon emission allocation is presented to achieve emission trading optimal economic efficiency of the whole system,which provides the beneficial reference for the launch of carbon emission trading and management in the future.The proposed model is verified by an example.
