考虑绿证和碳排放权交易的电力市场协同减碳效应与仿真

Synergistic carbon reduction effect and simulation of electricity market considering the green certificate and carbon emission trading

为解决电力行业降碳问题,同时考虑绿证和碳排放权交易机制,对两种交易机制的协同降碳效果进行定量分析,建立以各厂商利润最大化为目标的双层博弈模型,分析可再生能源配额比例和碳减排率对厂商决策行为的影响。针对免费碳配额的分配提出一种新的碳配额核定策略,并利用Karush-Kuhn-Tucker(KKT)条件将双层模型转化为单层模型进行求解。研究结果表明:新的碳配额核定策略既可以促进可再生能源发展,抑制煤电增长,又可以减少碳排放,助力“双碳”目标实现。该研究为各厂商联动及通过优化配置资源结构推动能源转型提供了参考。

In order to solve the problem of carbon reduction in the power industry,this paper considered both the green certificate and carbon emission trading mechanism,and made a quantitative analysis of the synergistic carbon reduction effect of the two trading mechanisms.A bi-level game model aiming at maximizing the profit of each manufacturer was established to analyze the influence of renewable energy quota ratio and carbon emission reduction rate on the decision-making behavior of manufacturers.A new carbon quota approval strategy was proposed for the allocation of free carbon allowances,and Karush-Kuhn-Tucker(KKT)condition was used to transform the bi-level model into a single-layer model.The results show that the new carbon quota approval strategy can not only promote the development of renewable energy,restrain the growth of coal power,but also reduce carbon emissions and help to achieve the carbon peaking and carbon neutrality goals.This research provides a reference for the linkage of various manufacturers and the promotion of energy transformation through optimizing the allocation of resource structure.
