Non-iterative Distributed Community Energy Management System

A non-iterative distributed community energy management system (CEMS) is presented in this paper. More specifically, each home energy management system (HEMS) in the community do not need to iteratively adjust its appliance scheduling to make their scheduling optimal to the entire community. Instead, each HEMS determines its appliance scheduling only once, based on its own interests, without having to consider whether its appliance scheduling is optimal from the perspective of the entire community. The central controller will then determine a solution that is optimal to the entire community by optimally dispatching the community's distributed energy sources according to the appliance scheduling of the HEMS. Distributed optimization and mixed-integer linear programming are used in developing the proposed CEMS. Simulation results shows that the proposed CEMS is effective, minimizing the total electricity cost of the entire community without needing each HEMS to iteratively adjust their appliance scheduling.
