Resilient and Extreme-Event-Aware Microgrid Using Energy Storage and Load Curtailment

Extreme events such as hurricane, earthquake, flooding, and cyber-attacks can result in power system blackout. Due to the high cost of power outage, appropriate planning, scheduling and preventive strategies should be considered to improve the resiliency of the power system. The optimal resource allocation in an area with high risk of extreme events occurrence is quite challenging. In this paper, a novel method is presented to improve the grid resiliency, from electrical point of view, in case of an extreme event with an emphasis on grid preparation. A multi-objective planning & control strategy is proposed at the pre-event stage. The proposed approach includes microgrid islanding, generation regulation, and load curtailment. Energy Storage Systems are considered as alternative resources in case of occurrence of extreme events. The effectiveness of the proposed method is assessed and compared to the equivalent conventional control scheme using a test case composed by the IEEE 13-bus distribution test feeders suitably adapted to include stochastic generation and energy storage systems. It is shown that our proposed strategy is able to cover the critical loads in all the 24-hour simulation study.
