摘要：

With the continuous promotion of“carbon emission peak and carbon neutrality”strategy in China, the green and low-carbon transformation of integrated energy systems is imminent. Aiming at the problems of poor flexibility of traditional carbon capture power plants and the difficulty in integrating wind power into the grid, a low-carbon economic dispatch model of the integrated energy system considering carbon capture power plants and multi-utilization of hydrogen energy is proposed. Firstly, the traditional carbon capture power plant is reformed by introducing a liquid storage tank to improve the operation flexibility of the power plant to deal with wind power fluctuations. Secondly, a multi-utilization structure of hydrogen energy including two-stage power-to-gas, hydrogen fuel cell, hydrogen storage tank and hydrogen-doped combined heat and power is constructed to fully exploit the coordinated operation potential of hydrogen energy utilization and the carbon capture power plant. On this basis, a cascaded carbon trading mechanism is introduced to establish a low-carbon economic dispatch model with the optimization objective of minimizing the sum of carbon trading, carbon sequestration, coal and gas purchase costs. The simulation results show that the proposed model can effectively improve the wind power accommodation level and energy utilization efficiency of the system, and has significant low-carbon economic benefits. In addition, the carbon trading benchmark price can be set properly to guide the system to increase the level of carbon capture. © 2024 Automation of Electric Power Systems Press.
