An Efficient Algorithm for Demand-Response Optimization in Smart Grid Power Communication Based on Edge-IoT

Demand-response is one of the influencing factors in power communication networks. Existing studies did not consider much about the information distribution problem in power communication demand-response, therefore, this paper proposed a new approach. The main idea is to propose a multihop cooperative caching algorithm to minimize the delay that occurs during the demand-response of user’s information. The repetition caching rate of the edge gateway is reduced by providing low-delay information by proposing a noncooperative game-based caching scheme. Finally, a distributed caching algorithm for a real scenario is proposed. Simulation results show that the proposed algorithm improved the system’s performance under various operating conditions. It averages a reduction in the information distribution latency to 55.88% of the original mode; the actual maximum response capacity is raised by an average of 40.12%, and the number of power users increases by 2.53% on average.
