Electricity-Carbon Interactive Optimal Dispatch of Multi-Virtual Power Plant Considering Integrated Demand Response

Abstract

As new power systems and dual carbon policies develop, virtual power plant cluster (VPPC) provides another reliable way to promote the efficient utilization of energy and solve environmental pollution problems. To solve the coordinated optimal operation and low-carbon economic operation problem in multi-virtual power plant, a multi-virtual power plant (VPP) electricity-carbon interaction optimal scheduling model considering integrated demand response (IDR) is proposed. Firstly, a multi-VPP electricity-carbon interaction framework is established. The interaction of electric energy and carbon quotas can realize energy complementarity, reduce energy waste and promote low-carbon operation. Secondly, in order to coordinate the multiple types of energy and load in VPPC to further achieve low-carbon operation, the IDR mechanism based on the user comprehensive satisfaction (UCS) of electricity, heat as well as hydrogen is designed, which can effectively maintain the UCS in the cluster within a relatively high range. Finally, the unit output scheme is formulated to minimize the total cost of VPPC and the model is solved using the CPLEX solver. The simulation results show that the proposed method effectively promotes the coordinated operation among multi-VPP, increases the consumption rate of renewable energy sources and the economics of VPPC and reduces carbon emissions.
