| Abstract: |
| In the context of global energy transition and climate change mitigation, the issue of global warming caused by coal-fired power plants and the negative impacts of insufficient renewable energy integration are urgent problems that need to be addressed. To this end, a co-generation CHP-CSP, the CHP consists of gas turbine and waste heat boiler, synergistic peaking optimization operation model considering carbon trading mechanism is established in this paper. The model mainly focuses on demand response and the participation of gas turbine assisted by concentrated solar power plant in grid peaking strategy considering waste heat collection, and analyzes the impacts of carbon trading price and compensation coefficients on system operation and carbon emission in the context of tradable carbon quota. The research results show that considering integrated demand response can achieve load peak-valley regulation and reduce the peaking demand of the integrated energy system. The hybrid CSP-CHP operation mode improves the utilization rate of renewable energy and reduces system carbon emissions. The framework proposed in this study reduces system operating costs by 7.5%, carbon emissions by 15.6%, and increases wind energy utilization by 9.3%. |
