“…Por ejemplo, alternativas orientadas a gestionar la carga de los VEs (da Silva et al, 2021), las cuales podrían evitar la necesidad de repotenciar la red de distribución. No obstante, cuando estas alternativas no son suficientes, la repotenciación asegura un servicio eléctrico más fiable, de mayor calidad y una reducción de pérdidas técnicas de la red (Melgar-Domínguez et al, 2022).…”

“…Los estudios eléctricos deben contemplar el comportamiento de la demanda eléctrica en el sector residencial, mediante el análisis de las curvas de carga, agregando el efecto de VEs y considerando de forma los diferentes patrones de conducción (Flath et al, 2014). Esa evaluación estima la 2 penetración máxima de VEs que la red de distribución puede hospedar con la infraestructura actual o, en otros casos, el operador de la red podría buscar alternativas que permitan modernizar dicha red y viabilizar dicha integración (Melgar-Domínguez et al, 2022).…”

Introducción. La tendencia mundial apunta al uso de vehículos eléctricos (VEs) y conlleva a la necesidad de realizar estudios para estimar la capacidad de las redes de distribución al incorporar estas nuevas cargas. El objetivo de este trabajo fue analizar el posible impacto de la conexión de VEs a una red de distribución de baja tensión en Honduras. Métodos. Se obtuvo información de consumos energéticos de los abonados y características de las líneas de distribución entre otros, utilizando datos de una red de baja tensión. Con la representación de una red de distribución de baja tensión, se analizó el posible crecimiento tanto en el consumo energético como en los picos de potencia debido a la conexión de VEs, estimando el incremento de la demanda con respecto a la capacidad instalada de la red. Se capturaron diferentes patrones de conducción, los cuales definieron la energía requerida para ser cargados y el horario de conexión y desconexión. Dicho impacto fue evaluado mediante un análisis de flujo de potencia cuando se alcanzaron picos de consumo. Resultados. Basado en los resultados obtenidos en la simulación, se observó que cuando se alcanzó una penetración de VEs de 50%, límites técnicos, como ser límites mínimos de tensión, podrían verse negativamente impactados. Conclusión. A medida la integración de VEs incremente en la red de distribución será necesario repotenciar la red eléctrica para suplir las nuevas necesidades de la demanda.

“…As the DG-HC term refers to the higher penetration level at which the DN still operates within accepted limits without infrastructure upgrading, some modifications, such as conductors oversizing, raising transformers ratings, and integrating voltage regulators, may enhance this DG-HC [178,179]. DN infrastructure upgrading was introduced as an effective solution for HC improvement in various recent publications [111,[178][179][180][181][182]. Depending on two upgrading alternatives, i.e.…”

“…Depending on two upgrading alternatives, i.e. replacing feeders, and installing voltage regulators, authors in [182] introduced a multi-objective optimization scheme to enhance DG-HC and minimize the upgrading cost simultaneously. To guarantee the proposed scheme robustness, load consumption and DGs output are considered time-varying and uncertain.…”

The excessive integration of renewable distributed generation (RDG) and electric vehicles (EVs) could be considered the two most problematic elements representing the greatest threat to the distribution network (DN) technical operation. In order to avoid going beyond technical limitations, the term hosting capacity (HC) was proposed to define the highest permitted amount of distributed generation (DG) or EVs that can be integrated safely into the DN. The connection of RDGs was first brought to the attention of researchers and DN operators since it accounts for the most notable portion of these technical issues. Hence, the phrase 'DG-HC' was initially proposed and evolved significantly over the last few years. Currently, EV integration in most DNs worldwide is still low, but given the worldwide support for clean transportation options, expectations are raised for a significant increase. As a result, it is anticipated that over the next years, the effect of EV integration on the DN will be highly noticeable, requiring greater attention from researchers and DN operators to define the accepted limits of EV penetration levels, 'EV-HC,' which is expected to pass along the same line of DG-HC. This article provides an in-depth review of both DG-HC and EV-HC. It first analyses how the DG-HC research has grown over the years and then studies the published EV-HC papers, illustrating to what extent there is a similarity between them and, finally, employs these analyses to expect future development in the EV-HC research area. This article includes the different uses of the term HC, the most common performance indices of DG-HC, the various methods for assessing DG-HC, the different techniques for DG-HC enhancement, the effects of integrating EVs on the DG-HC, and finally, calculating and enhancing methods for EV-HC.

Electrical power systems with their components such as generation, network, control and transmission equipment, management systems, and electrical loads are the backbone of modern life. Historical power outages caused by natural disasters or human failures show huge losses to the economy, environment, healthcare, and people’s lives. This paper presents a systematic review on three interconnected dimensions of (1) electric power system resilience (2) the electricity supply for/through Electric Vehicles (EVs), and (3) social vulnerability to power outages. This paper contributes to the existing literature and research by highlighting the importance of considering social vulnerability in the context of power system resilience and EVs, providing insights into addressing inequities in access to backup power resources during power outages. This paper first reviews power system resilience focusing on qualitative and quantitative metrics, evaluation methods, and planning and operation-based enhancement strategies for electric power systems during prolonged outages through microgrids, energy storage systems (e.g., battery, power-to-gas, and hydrogen energy storage systems), renewable energy sources, and demand response schemes. In addition, this study contributes to in-depth examination of the evolving role of EVs, as a backup power supply, in enhancing power system resilience by exploring the EV applications such as vehicle-to-home/building, grid-to-vehicle, and vehicle-to-vehicle or the utilization of second life of EV batteries. Transportation electrification has escalated the interdependency of power and transportation sectors, posing challenges during prolonged power outages. Therefore, in the next part, the resilient strategies for providing electricity supply and charging services for EVs are discussed such as deployments of battery swapping technology and mobile battery trucks (MBTs), as well as designing sustainable off-grid charging stations. It offers insights into innovative solutions for ensuring continuous electricity supply for EVs during outages. In the section on social vulnerability to power outages, this paper first reviews the most socioeconomic and demographic indicators involved in the quantification of social vulnerability to power outages. Afterward, the association between energy equity on social vulnerability to power outages is discussed such as inequity in backup power resources and power recovery and restoration. The study examines the existing challenges and research gaps related to the power system resilience, the electric power supply for/through EVs, social vulnerability, and inequity access to resources during extended power outages and proposes potential research directions to address these gaps and build upon future studies.
