Optimization of Power Supply Structure Considering Carbon Emissions and Flexibility

Abstract

Against the backdrop of China’s promotion of green and low-carbon energy transformation, the large-scale and high-proportion development of new energy has made flexible regulation of power supply planning a key link in the flexible construction of the power system. Considering the balance of flexible supply and demand and minimizing carbon emissions, a mid to long-term collaborative planning model for electricity and flexibility is proposed. According to the planning principles of economic efficiency, clean environmental protection, and safety and reliability, a dynamic planning model was constructed to minimize the total cost of electricity production and carbon emissions in the entire society. Taking into account constraints such as carbon peaking goals and electricity balance, taking a certain region in China as an example, a flexible power supply structure optimization planning is carried out to solve carbon emission levels and system costs, output carbon peaking time, and optimal path plan.
