An Improved Priority-Based Load Shedding Scheme in Hybrid AC/DC Microgrids Using Micro-PMUData

摘要

Load Shedding (LS) is an effective approach to maintain or restore the steady-state operation of the power system when a disturbance occurs. Load shedding in islanded distribution system should not only be done considering technical reasons but also the priority of loads and economic reason should be considered. This paper proposes an advanced priority-based load shedding solution based on dynamic power flow tracing method for AC/DC microgrids. The simulation results prove that the proposed technique is capable of achieving the optimal load shedding and recovering frequency to nominal value in AC/DC microgrids.
