Abstract

Abstract:

With the reform of China's power market and the promotion of energy conservation and emission reduction policies, there are more and more market-oriented policies for the power generation industry. From the perspective of coal-fired power generation enterprises participating in carbon-emission right market and power generation right market, aiming at maximizing enterprise profits, this paper studies five combined trading strategies of power producers in the power market, and uses the fmincon function in Matlab to optimize the power generation plan of power generation enterprises, so as to maximize their own economy under many policy backgrounds. The results show that for large capacity units with environmental protection and energy conservation, the profits obtained by trading generation rights and carbon-emission rights at the same time are significantly higher than those obtained by trading generation rights or carbon-emission rights alone; For some units with high power generation cost, all their power-generation rights can be sold to obtain certain profits. At the same time, the effects of auction proportion and power-generation right price on enterprise profits and carbon emissions are analyzed.

Key words: carbon-emission right, power-generation right, electricity market, trading strategy, optimization theory
