The combination of combined heat and power (CHP) units and virtual power plants (VPP) can effectively improve energy utilization efficiency and enhance the reliability and stability of power system operation. To ensure the flexible,low-carbon,and economical operation of the CHP-VPP,this paper proposes an integrated energy VPP that aggregates wind power,photovoltaics,CHP units,boilers,carbon capture equipment,gas turbines,fuel cells,energy storage,and electricity and heat loads. The low-carbon economic coordinated scheduling issues are also investigated,considering multiple markets such as electricity,heat,spinning reserves,and carbon trading. Specifically,a two-stage robust optimization scheduling model for the CHP-VPP is established with the goal of maximizing the overall revenue in multiple markets at each time period. Then,considering the uncertainties from renewable energy outputs,market prices and loads,Monte Carlo method is used for scenario reduction to minimize system risk and enhance its robustness. Finally,a column and constraint generation algorithm is employed to solve the model,obtaining the optimal economic scheduling scheme in the worst-case scenario. Simulation case studies are carried out. Results show that the proposed integrated energy VPP structure is feasible and can achieve a significant reduction in carbon emissions through dynamically adjusting carbon capture equipment and energy storage batteries to achieve smoothness in renewable energy output fluctuations. Furthermore,the proposed scheduling strategy can effectively ensure the coordinated optimization operation of electricity and heat resources in source-load-storage sides,enhancing the flexibility,economy,and low-carbon performance of VPP.
