Abstract：This study proposes a multi-form and multi-characteristic load model for virtual power plants(VPPs),utilizing the full potential of user-side electrical and thermal flexible loads.The proposal entails the implementation of an economic dispatch model that incorporates a carbon trading mechanism.This mechanism is designed to reduce carbon emissions by means of optimal dispatch strategies.The model's functionality encompasses the generation of carbon transaction revenues,thereby enhancing system's economic efficiency.The findings of the analysis demonstrate that this model exhibits a substantial enhancement in performance when compared with conventional independent electro-thermal dispatch modes with regard to system-coupled dispatch.The system has been shown to optimize electro-thermal load curves by implementing techniques such as peak shaving and valley filling through load curtailment or shifting.Furthermore,in a multitude of scenarios,the integration of flexible loads and their synergistic effects among components substantially reduce the operating costs of integrated energy systems,thereby achieving the objective of economic dispatch for VPPs.
