Multi-Stage Multi-Objective Energy Management System for Seaport DC Microgrids

In this paper, a multi-stage optimal economic dispatch algorithm has been proposed for the seaport DC microgrid to support the main grid while feeding the local loads. Based on the real-time grid tariff, the optimized charging and discharging decisions for the ESSs have been initiated. The optimization algorithm has been split into two parts to solve the optimization problems: a rule-based algorithm and the Genetic Algorithm (GA). The results have shown that the proposed EMS can effectively schedule the ESS devices while considering the economic benefits of the system. The work has been performed on the MATLAB platform using the GA optimization tool.
