Study on Emission Reduction Strategy and Carbon Compliance Risk of Large Power Users Under the Background of Carbon-Electricity Coupling Market and Demand Response

In the context of China's carbon peaking and carbon neutrality goals, the future will witness a gradual increase in the proportion of renewable energy consumption. Large power users, characterized by high electricity demand and carbon emissions, play a crucial role in both the electricity market and the carbon trading market. Therefore, studying the market trading demand, strategies, and risks for these users within the framework of carbon-electricity market and demand response (i.e., clean energy consumption) is of significant importance. This research focuses on large power users in the steel industry and screens the key factors influencing power and carbon trading. The study also analyzes the coupling mechanism between the carbon and electricity markets. Based on this analysis, a system dynamic trading model is developed, taking into account renewable energy quota constraints, policy constraints, economic benefits, environmental values, and other factors. The model simulates the participation of large users in both the power market and the carbon market. The results indicate that, under renewable energy planning, an increase in the consumption ratio leads to higher power purchase costs for large users and an overall increase in the cost of carbon-electricity coupling market trading. However, the impact on trading risk is minimal. These comprehensive analysis results provide valuable insights for designing carbon-electricity coupling market trading models for large power users under renewable energy consumption policies.
