“…Preventive control measures including risk-based annual pole replacement (Mohammadi Darestani et al, 2021), optimal coordination of power system schedules (Yan et al, 2019) and network reconfiguration and repair crew prepositioning (Taheri et al, 2019) have been studied. To accomplish a risk-based annual pole replacement, probabilistic methods were utilised to line up poles based on the drop in risk of power outage in the distribution network when a pole is replaced (Mohammadi Darestani et al, 2021). Expected outage reduction and national electric safety codes strategies were applied to a power distribution system with over 7000 nodes.…”

Power system resilience enhancement (PSRE) describes approaches used in reducing the extent of direct impacts caused by climate change and approaches in quickly restoring the grid functionality to its usual status. Recently, much research has been conducted on PSRE approaches to the effects of climate change. There a re abundant review papers on PSRE to the impacts of climate. But there are no significant amounts of review papers focusing on operational resilience enhancement approaches on the entire power system, particularly with the focus and classifications suggest ed in this paper. Operational resilience-oriented modelling approaches and strategies have been comprehensively reviewed across five distinct dimensions including operational strategy, enhancement type, hierarchy, modelling methods and model formulation. A standard literature review process was followed to identify articles, with the initial search covering PSRE in general. Out of these, papers focusing on operational resilience enhancement were selected. The selected papers were classified according to the operational enhancement approaches, enhancement types, modelling methods, model formulation and the enhanced hierarchy criteria. The operational approaches, which include distributed energy resources, microgrids, preventive control, response, design stand ards upgrade, advanced visualisation and situational awareness systems and advanced and adaptive restoration operational techniques, were reviewed. The study reveals that for a single operational approach, different enhancement techniques can be employed using different modelling techniques. However, limited studies have so far explored an entire grid improvement as opposed to transmission and distribution structures. In addition, among the optimisation, probabilistic, simulation and AI based modelling met hods, optimisation approaches have been extensively used. As lots of assumptions were built to demonstrate the resilience challenge solutions, the adoption of authentic existing power system data related to the severities of each event and system resource data may be appropriate in demonstrating resilience improvement solutions. There are very limited studies that combine these modelling approaches in one study. Research gaps and directions for future research have been suggested in this paper.

Disadvantaged communities are disproportionately affected by flooding, exacerbated by climate change. This paper presents a novel framework for incorporating environmental justice into climate adaptation planning of power grids against flooding. A new energy equity metric is introduced with the vision that addressing environmental justice warrants prioritizing disadvantaged communities that have lower risk thresholds. The framework is applied to a levee-protected IEEE standard test system in northern California. The grid performance disturbed due to flooded substations is investigated under current and future climate. The mathematical model of the framework is structured as a two-stage stochastic mixed-integer programming model. This model aims to minimize the equity gap in grid resilience (EGGR) between disadvantaged and non-disadvantaged communities while enhancing the system resilience by reducing the risk of power outages due to flooding. The results show that climate change undermines grid resilience, with disproportionally worse impacts on disadvantaged communities. A significant EGGR is observed that worsens under a changing climate. For adaptation, the optimal placement of distributed energy resources is determined by maximizing the grid resilience to flooding while minimizing EGGR. The proposed framework can equip decision-makers with a robust tool for operationalizing equitable climate adaptation strategies for power grids.

“…Despite severe consequences caused by falling trees, the tree-failure risk has not been systematically considered in previous studies on resilience modeling of PDS against extreme winds. Most previous resilience assessment frameworks for PDS only considered wind-induced component failures, neglecting failures caused by falling trees (Salman et al 2015; Unnikrishnan and van de Lindt 2016; Hughes et al 2021;Mohammadi Darestani et al 2021). Although some studies considered the tree-failure risk, there are limitations in these studies.…”

Modeling the Resilience of Power Distribution Systems Subjected to Extreme Winds Considering Tree Failures: An Integrated Framework

Overhead electrical power distribution systems (PDS) are very susceptible to extreme wind hazards. Power outages can cause catastrophic consequences, including economic losses, loss of critical services, and disruption to daily life. Therefore, it is very important to model the resilience of PDS against extreme winds to support disaster planning. While several frameworks currently exist to assess the resilience of PDS subjected to extreme winds, these frameworks do not systematically consider the tree-failure risk. In other words, there is no integrated framework that can simultaneously consider tree failures, PDS component failures induced by falling trees, resilience assessment, and evaluation of resilience enhancement with vegetation management. Therefore, this study proposed an integrated simulation framework to model the resilience of PDS against extreme winds, which includes tree fragility modeling, PDS fragility modeling, PDS component failure estimation, system performance evaluation, system restoration modeling, and resilience enhancement evaluation. The framework is demonstrated with a power distribution network in Oklahoma. The results show that the estimated system resilience will reduce if tree failures are considered. Crown thinning can effectively enhance the system’s resilience, but the effectiveness is affected by both wind speed and direction.
