Abstract: The application of edge computing in power communication network facilitates the operation of ultra-low latency demand response (DR) and promotes the development of energy market. However, current works mainly focus on the application of edge computing in DR data execution, and the information distributing problem in DR has received little attention. This paper minimized the impact of DR information transmission delay on response capacity of users and proposed a multi-hop cooperative caching method. To optimize transmission delay, a noncooperative game-based caching algorithm considering cooperation region was proposed, and thus the edge gateway can compete with each other to provide low-delay information service while decreasing the repetition caching rate. Considering the practical in real scenario, a distribution algorithm was designed to achieve distributed caching decision. The simulation results show that the proposed strategy can optimize the transmission delay of DR information and improve the actual maximum responsiveness of the users.
