Cost Benefit and Alternatives Analysis of Distribution Systems with Energy Storage Systems

Abstract

This paper explores monetized and non-monetized benefits from storage interconnected to a distribution system through use cases illustrating potential applications for energy storage in California's electric utility system. This work supports SDG&E in its efforts to quantify, summarize, and compare the cost and benefit streams related to implementation and operation of energy storage on its distribution feeders. This effort develops a prototype cost benefit and alternatives analysis platform, integrates with QSTS feeder simulation capability, and analyzes use cases to explore the cost-benefit of the implementation and operation of energy storage for feeder support and market participation.
