Microgrid management in emergency scenarios for smart electrical energy usage

Abstract

Power system blackouts harm economic activities and worsen the customers' welfare. Smart grids' self-healing capacity is an important feature for future power systems and it should also include the ability to manage the distributed energy sources to ensure electricity supply for a long time. This is required because the blackout duration is unknown and buck power system blackstart is a complex task. This paper proposes a methodology for microgrid management and control to maximize the duration of electricity supply in emergency situations. In order to accomplish this goal, some management options are considered as intentional load shedding, dispatch of expensive fossil fuel sources, system reconfiguration and so on. The proposed methodology is tested with the IEEE 34 node test-system to investigate its feasibility.
