  • Publication number: 20240330396
    Abstract: A microgrid spatial-temporal perception energy management method based on safe deep reinforcement learning includes: transforming an energy management problem of a microgrid (MG) into a constrained Markov decision process (CMDP), where an agent is an energy management agent of the MG; and solving the CMDP by using a safe deep reinforcement learning method, including: 1) building a feature extraction network combining an edge conditioned convolutional (ECC) network and a long short-term memory (LSTM) network to extract spatial and temporal features in a spatial-temporal operating status of the MG; and 2) endowing the agent with abilities to learn policy value and security simultaneously by using an interior-point policy optimization (IPO) algorithm.
