Research on the evaluation method for virtual power plant technology promotion and application benefits

Abstract

Virtual power plant technology (VPP), by aggregating “source-load-storage” multi-link resource coordination and interaction, has significant benefits in improving energy utilization efficiency and promoting new energy consumption and plays a positive role in the construction of new power systems. And scientific and effective evaluation of its technology popularization and application is an important premise to promote its development. Aiming at the characteristics of VPP technology involving a wide range, of many types of resources, and complex evaluation indicators, this paper introduces a subjective and objective weighting method combining the AHP-entropy weighting method to make up for the shortcomings of a single weighting method. First, combined with the current “dual carbon” strategy and the development of the new situation of “re-electrification”, and comprehensively considering the four aspects of VPP economic benefits, environmental benefits, social benefits, and technology promotion, a comprehensive evaluation index system for VPP technology promotion benefits was constructed. The evaluation method is difficult to meet the considerable evaluation needs. A method combining the subjective and objective methods of the AHP-entropy weight method is established to solve the weight of each index and to realize the scientific evaluation and reasonable quantification of each index. Finally, the national VPP demonstration project is selected.
