A new multi-objective load shedding method to reduce power outages and frequency stability in the islanded microgrid

Power systems are complex systems that are not easy to understand and analyze. Also, many faults and incidents occur in these systems, many of which are mended without human interference. Meanwhile, electricity companies are responsible for the security of power systems and operators because if any part of the power system acts as an unwanted island, it may be unsafe for grid personnel and may result in serious damages to grid equipment. Therefore, it is important and necessary to identify the parts of the grid, which have become islands, and apply load shedding to abolish these islands. This paper proposes a new approach for load shedding in the islanded microgrid in the presence of distributed generations. Features of the proposed method include high flexibility, speed, and accuracy. The proposed method is simulated by powerful DIgSILENT software, and the simulation results support the capability of the proposed method.
