| Title: Optimal scheduling and advanced control of Supercritical Coal-fired Power Plant integrated with Post-Combustion CO2 Capture in the context of high renewable energy penetration | |
| Abstract: Post-combustion carbon dioxide capture technology based on chemical solvent is currently the most promising technology for coal-fired power plant flue gas carbon capture. Because coal-fired power plants are widely involved in peak regulation and the chemical solvent regeneration requires to consume huge amount of heat, it is of great significance to conduct overall scheduling and control research on the integrated coal-fired power plant-carbon capture process to achieve flexible operation of the system. This study develops a high-precision simulation platform for Supercritical coal-fired power plant-carbon capture system. An overall optimal scheduling method for power plant carbon capture system in the context of renewable energy penetration is proposed, and the role of power plant-carbon capture system in future low carbon energy mix is studied. A novel control scheme for the power plant-carbon capture is proposed based on the model predictive control (MPC) to track the scheduling results, in which the re-boiler steam flowrate is incorporated in the boiler-turbine coordinated control system to assist the regulation of power output and the lean solvent flow is used to control CO2 capture rate in the carbon capture system. By making full use of the interactions and time scale difference between the supercritical coal-fired power plant and the solvent-based post-combustion carbon capture system, the proposed approach can effectively improve the load response speed of the power plant, making it have a stronger peak-shaving capacity of the power grid with limited impact on the operation of the carbon capture system. | |
