Optimal scheduling of intelligent virtual power plants based on explainable reinforcement learning
With the increasing popularity of electric vehicles(EVs),energy systems are becoming more complex.Virtual power plants(VPPs)can aggregate and optimize distributed energy resources such as distributed generation,energy storage systems,controllable loads,and EVs through internet of things(IoT)and artificial intelligence(AI)technologies,enhancing energy efficiency and facilitating the consumption of non-renewable energy while reinforcing grid stability.However,current AI technologies lack reliability and transparency in high-safety applications like power systems,potentially making it challenging for users and operators to understand how algorithms make specific energy allocation decisions.To address the balance between achieving optimal scheduling of VPPs utilizing AI and explaining the decision-making processes,this study proposed an interactive framework based on explainable reinforcement learning.This framework employed the proximal policy optimization(PPO)algorithm for optimal scheduling of VPPs and constructed an explainable reinforcement learning framework using decision trees to provide transparent decision support that enabled non-expert users to understand AI's decision-making processes in regulating energy systems.The results indicated that compared to traditional reinforcement learning optimization methods,this approach not only improved energy allocation efficiency but also strengthened user trust in intelligent VPP management systems by enhancing model interpretability.
