“…In the baseline specification, this means the additional impact is independent of the number of weather events. However, the impact of an additional weather event on availability and accessibility may compound the effect of previous weather events or have less of an impact than the previous event [62]. In the second specification, we include a term for the number of extreme weather events squared to account for this possible non-linearity.…”

Extreme weather events are increasing in frequency and severity due to climate change, yet many of their impacts on human populations are not well understood. We examine the relationship between prior extreme weather events and food environment characteristics. To do so, we conduct a U.S. county-level analysis that assesses the association between extreme weather events and two common food retail environment dimensions. Overall, we find a relationship between higher levels of historic extreme weather exposure and lower food availability and accessibility. In addition, we find heterogeneity in association across the distribution of the number of extreme weather events and event type. Specifically, we find that more localized extreme weather events are more associated with a reduction of access and availability than broad geographic events. Our findings suggest that as extreme weather events amplify in intensity and increase in frequency, new approaches for mitigating less acute and longer-term impacts are needed to address how extreme weather may interact with and reinforce existing disparities in food environment factors. Furthermore, our research argues that integrated approaches to improving vulnerable food retail environments will become an important component of extreme weather planning and should be a consideration in both disaster- and food-related policy.

“…A resilient transmission expansion planning model that optimizes the configuration of the transmission network was presented in [14], minimizing cascading outage effects and enhancing resilience by considering security and N − 1 security criterion, utilizing an iterative algorithm to estimate cascading outages, and employing a multistage solution procedure based on Benders decomposition algorithm for the efficient handling of investment decisions and resilience requirements. In [15], a resilience-oriented distribution system planning strategy was introduced, utilizing a multistage hybrid-stochastic-robust formulation with a progressive hedging algorithm, aiming to enhance power system resilience by addressing the challenges of multiple extreme weather events in the context of increasing renewable penetration and climate change uncertainties. The study presented in [11] introduced a planning strategy focused on resilience for the optimal setup of urban multienergy systems.…”

This article presents a resilient Integrated Resource Planning (IRP) framework designed for transmission systems, with a specific focus on analyzing and optimizing responses to High-Impact Low-Probability (HILP) events. The framework aims to improve the resilience of transmission networks in the face of extreme events by prioritizing the assessment of events with significant consequences. Unlike traditional reliability-based planning methods that average the impact of various outage durations, this work adopts a metric based on the proximity of outage lines to generators to select HILP events. The system’s baseline resilience is evaluated by calculating load curtailment in different parts of the network resulting from HILP outage events. The transmission network is represented as an undirected graph. Graph-theoretic techniques are used to identify islands with or without generators, potentially forming segmented grids or microgrids. This article introduces Expected Load Curtailment (ELC) as a metric to quantify the system’s resilience. The framework allows for the re-evaluation of system resilience by integrating additional generating resources to achieve desired resilience levels. Optimization is performed in the re-evaluation stage to determine the optimal placement of distributed energy resources (DERs) for enhancing resilience, i.e., minimizing ELC. Case studies on the IEEE 24-bus system illustrate the effectiveness of the proposed framework. In the broader context, this resilient IRP framework aligns with energy sustainability goals by promoting robust and resilient transmission networks, as the optimal placement of DERs for resilience enhancement not only strengthens the system’s ability to withstand and recover from disruptions but also contributes to efficient resource utilization, advancing the overarching goal of energy sustainability.
