Evaluation of Green and Low Carbon Benefits and Collaborative Optimization of Electrical Carbon Coupling in Power Systems

As society develops and progresses and people’s concept of life changes, the demand for low carbon and green living is becoming increasingly strong. Starting from the evaluation of green and low carbon benefits, this article studied the coupling and synergy of electrical carbon in the power system, and comprehensively considered its role in economic, environmental, and social benefits to comprehensively evaluate green and low carbon projects. The shadow price method was used to create a carbon emission assessment method, and the indicators that affect carbon emissions were studied. At the same time, the coupling phenomenon of electrical carbon in the power system was studied, and a two-stage system optimization model was constructed, providing a decision-making basis for policy-making. This article selected three scenarios to study the equilibrium of the electricity market in these three scenarios. It was found that under the background of green and low carbon benefit evaluation, the total income of scenarios $1-3$ was higher than before the experiment by 20134.9 yuan, 31267.2 yuan, and 39448.6 yuan, respectively. Studying the relationship between power generation and carbon emissions in the power system can achieve low carbon and efficient operation of the power system, providing theoretical and practical support for the promotion of green and low carbon.
