Enhancing power system resilience leveraging microgrids: A review

Abstract

An electrical power system is considered as a critical infrastructure (CI), the epicenter of a nation's economy, security, and health. It is interlinked with other CIs such as gas and water supplies and transportation and communication systems. A failure in the power system will immensely affect the functionality of these CIs. Therefore, enhancing power system resilience is crucially needed to ensure continuous operation of these CIs. One of the possible approaches to improve the resilience in a power system is by integrating microgrids in the power system. Microgrids have proven to have self-healing and resilient capabilities in such extreme events which inflict damage out of the conventional scope of failures. Operational flexibility and controllability make microgrids a viable solution for resilience enhancement. This paper reviews the concept of resilience in power systems and the functions of microgrids in enhancement of resilience. The most current studies in improving power system resilience through microgrids are reviewed by highlighting their advantages and limitations.

An overview of the assessment metrics of the concept of resilience in electrical grids

“…It should be noted that the objective of this paper is not to review the various methods presented to improve the resilience of a system or grid, as this has been done in several studies, 11,13,15,18,[45][46][47][48][49][50] rather it aims to compare the various metrics employed to evaluate the resilience of electrical grids.…”

Gestión De Una Red Eléctrica De Distribución Ante Desastres A Partir De Recursos Energéticos Distribuidos

“…En el contexto energético, se define la resiliencia como "la capacidad de recuperación de un sistema de energía para tolerar perturbaciones y continuar brindando servicio de energía asequibles a los consumidores" y el sistema resiliente de energía puede recuperarse rápidamente de daños y proporcionar medios alternativos para satisfacer de energía a las necesidades de servicios en circunstancias extremas (Chaudry, 2011) (Bajwa et al, 2019).…”

Weather-Driven Predictive Control of a Battery Storage for Improved Microgrid Resilience

“…During MG operation, a BESS improves resilience during operation in the island mode. Resilience is a relatively new concept in power systems, and in recent years, it has had a significant impact on the definition of the reliability of electricity distribution networks [4]. The definition proposed by [5] involves energy systems being able to recover fast from events caused by external factors.…”
