Optimization Method for Low-Carbon Economic Dispatch of Carbon Capture Power Plants Considering Market Power Constraint in Carbon Trading Market

The phenomenon of market power abuse in carbon trading, leading to deviations in carbon quota prices from normal competitive levels, poses a significant challenge to the economic dispatch of carbon capture power plants. In response, this paper introduces a comprehensive market power assessment methodology tailored to the carbon market environment in China, encompassing pre-market, mid-market, and post-market phases. Furthermore, it proposes market power restraint measures based on the incentive compatibility principle. Comparative analysis is conducted to validate that the implementation of market power restraint can prevent the masking of true cost information, thereby enhancing the low-carbon operational efficiency of carbon capture power plants.
