Mobile Energy Storage Configuration Methods for Distribution Grid Supply Maintenance

Significant advancements have been made in the study of mobile energy storage deployment within distribution networks. This paper contributes to this field by presenting a method for configuring mobile energy storage systems oriented towards ensuring power supply reliability in distribution grids. The approach dissects the problem into two interconnected stages: firstly, the siting of mobile energy storage units within the grid, and secondly, the selection of appropriate mobile energy storage vehicles. In constructing the model for allocating these mobile energy storage devices, comprehensive considerations are given to both the time required for the storage vehicles to reach outage nodes and the load demands that must be met. The paramount objective is to identify optimal parking locations for these vehicles, thereby guaranteeing a swift response and timely arrival at outage sites. This strategy aims to minimize downtime and reinforce the stability of electricity provision. User satisfaction constraints are integrated into the model to ascertain the minimum power capacity needed from the mobile energy storage devices. Subsequently, with cost efficiency in mind and leveraging knowledge of the available types of mobile energy storage vehicles and their respective capabilities, the most suitable vehicles are selected to fulfill the determined requirements. This dual-phase methodology systematically enhances the resilience of distribution networks by optimizing the placement and selection of mobile energy storage assets under real-world operational constraints.
