Research on No-baseline Effect Assessment Method based on Virtual Power Plant Response

A virtual power plant (VPP) aggregates various dispersed resources in the distribution network into a unified whole, enhancing the global responsiveness of the aggregated resources. Additionally, it can participate in power market transactions as a whole, improving the dispatchability of resources and operational economy. In this paper, we develop an evaluation model for VPP responsiveness that leverages the absolute response volume of the VPP. Four key indicators are introduced—response volume, response accuracy, load tracking, and power stability—to provide a comprehensive assessment of the system’s performance. Building upon these indicators, we propose an overall responsiveness evaluation method and employ an entropy-weighting approach to calculate a final responsiveness score. Finally, through a 24-hour case study, we derive the VPP’s response capability curve and corresponding scores.
