基于政府补贴的微电网企业碳价动态机制研究

he development of renewable energy micro grid is highly dependent on government subsidies. In recent years, the gap of subsidies has gradually expanded. Therefore, the study of carbon trading market compensation microgrid has important theoretical and practical significance. In this paper, based on the analysis of the interest divergence and decision-making characteristics of the government and Microgrid, the stackbelberg differential game model is established, and the decision variables of the players are simulated. The results show that the positive correlation between carbon price and carbon emission reduction conforms to the general economic law that supply is stimulated by price, and the substitution effect of carbon price on government subsidy is confirmed from the static and dynamic perspectives with the decrease of carbon price and time. In addition, the carbon price sensitivity coefficient and cost coefficient may lead to the reduction of carbon price and the increase of subsidy. Therefore, it is suggested to increase the research and development of low-carbon technology, reduce the threshold of controlling emission units, and provide more liquidity for the carbon trading market.
