摘要
With the popularization of electricity data acquisition systems, the application of data-driven machine learning methods has played a significant role on optimal decision-making in demand response. In this paper, based on the real-time feedback data from the charging monitoring system and TOU tariff, a deep reinforcement learning (DRL) method is proposed to optimize the charging strategy of the electric vehicles (EVs) from the perspective of aggregator. A twin delay deep deterministic policy gradient (TD3) algorithm is implemented to model the charging process of a single vehicle. By adding randomly the noises in the states of the trained agent, our model attained generalized abilities to control EV charging strategies under divergent states. With the distributed deployment of the well-trained agents, this method realizes the real-time optimization of aggregated EVs' charging strategy, which is proved with examples. © 2021, Power System Technology Press.
