Power system resilience is defined as the ability of power grids to anticipate, withstand, adapt and recover from high-impact lowprobability (HILP) events. There are both long-term and short-term measures that system operators can employ for resilience reinforcement. Longer-term measures include infrastructure hardening and resilient planning, while short-term operational measures are applied in the pre-event, during-event and post-event phases. Microgrids (MGs) can effectively enhance resilience for both transmission and distribution systems, due to their ability to operate in a controlled, coordinated way, when connected to the main power grid and in islanded mode. In this paper, MG-based strategies for resilience enhancement are presented, including MGbased resilient planning and MG-based operational measures, consisting of preventive MG scheduling and emergency measures and MG-based system restoration. Classification of literature is made by considering whether the transmission system, distribution system or individual MG resilience is targeted. The way uncertainties are handled by various methods is also outlined. Finally, challenges and future research requirements for improving MG-based power system resilience are highlighted.

Three Lines of Defense for Wildfire Risk Management in Electric Power Grids: A Review

et al. 2021

View full text Add to dashboard Cite

Wildfires pose a significant challenge to the natural and the built environments, as well as the safety and economic wellbeing of the communities residing in wildfire-prone areas. The electric power grid is specifically among the built environments most affected by, and contributing to, wildfires. In this paper, we propose a three lines of defense (3LD) framework for wildfire risk management in electric power infrastructure and review the literature from this lens. An overview of the physics and phenomenology of the wildfires as it relates to power grids is presented, and the logic for the proposed 3LD framework is discussed. The reviewed literature based on the 3LD theme includes the most relevant and emerging research work on wildfire prevention as the first line of defense, wildfire mitigation and proactive response as the second line of defense, and wildfire recovery preparedness as the third line of defense. This study reveals that while the state of the art, to a large extent, stands comprehensive in various aspects of power system resilience and wildfire risk management, there is a gap in the literature in addressing this emerging risk in a holistic, interdisciplinary approach.

“…The first category considers short-term horizons and focuses on the scheduling of operational activities. Pre-event allocation of available resources to enhance the system withstanding [10][11][12][13][14][15][16] and provision of post-event restoration strategies like microgrid (MG) formation [17][18][19] are the main contributions of these research studies. On the other hand, the second category addresses the system resiliency enhancement from the planning point of view by optimally investing and modernizing the network, 20,21 hardening the infrastructures, 22 optimal resource allocation, 23 fast and effective restoration planning, 24 and considering the repair crew.…”

A novel resource allocation model based on the modularity concept for resiliency enhancement in electric distribution networks

et al. 2021

Paying attention to the modularity feature of electric distribution systems improves their performance against severe events and makes an outstanding opportunity for resiliency enhancement. In this paper, a novel framework based on the modularity concept is proposed in which, by deploying smart grid technologies and forming efficient modules, effective and robust energy in distribution systems is provided. Optimal placement of distributed generation (DG) resources, load control options, switching devices, and tie lines are simultaneously incorporated in the proposed linear allocation model. To consider electrical and topological characteristics in the independent functioning of the formed modules, a path-based method is employed. The effectiveness and computability of the proposed algorithm are examined by performing several simulations on two modified 37-bus and 84-bus test systems. The results demonstrate that the developed modular structure, by subdividing the system into several independent parts, creates more flexibility for the recovery process and facilitates the self-healing capabilities.
