An allocative method of stationary and vehicle-mounted mobile energy storage for emergency power supply in urban areas

Abstract

Extreme climate events are on the rise, posing significant challenges to power systems, leading to blackouts and infrastructure damage. Energy storage plays a crucial role in enhancing grid resilience by providing stability, backup power, load shifting capabilities, and voltage regulation. While stationary energy storage has been widely adopted, there is growing interest in vehicle-mounted mobile energy storage due to its mobility and flexibility. This article proposes an integrated approach that combines stationary and vehicle-mounted mobile energy storage to optimize power system safety and stability under the conditions of limiting the total investment in both types of energy storages. The principal aim is to minimize the weighted energy not served index in the presence of fault conditions. By strategically allocating energy storage resources and dynamically dispatching stored energy, operators can ensure rapid response and effective power restoration, improving overall reliability in the face of extreme weather events.
