Coordinated Planning and Profit Distribution of Wind, Solar and Thermal Power Considering the Low-carbon Transformation of Thermal Power

Abstract

Double-Carbon Policy has created a major change to the development of power system, and new power system with high percentage of clean energy has become the main goal of China's future power industry development. Under the background, the flexibility and stability of thermal power are particularly prominent because wind power and photovoltaic have high uncertainty. However, carbon emissions from thermal power generation have always been at high levels in the past, which puts great pressure on power systems to reduce carbon emissions. Therefore, this paper proposes a model of coordinated planning and profit distribution of wind, solar and thermal power considering the low-carbon transformation of thermal power. Shapley value method is used to distribute profits, the piecewise linearization strategy is used to solve the model, and core theory is used to verify the existence of cooperative games. The proposed method is applied to an example to verify the effectiveness. The profits of various market players can be guaranteed, and the low-carbon transformation strategy of thermal power units can reduce the overall carbon emissions of the power system while ensuring economic efficiency.
