On the greedy placement of energy storage systems in distribution grids

This paper considers power distribution grids and addresses the problem of finding optimal placement strategies for energy storage systems. The placement problem is, unfortunately, combinatorially complex. A placement strategy with performance guarantees based on submodularity theory and greedy methods is proposed. The greedy method is then compared with a heuristic strategy that relies on voltage sensitivity analysis. The features of both techniques are discussed and illustrated through an application to a test feeder.
