This research aims to examine the potential value of Energy Storage Systems (ESSs) to different sects of the electrical power system through the various applications in which it could be utilized. The different storage technologies are reviewed in light of the sector of the grid (generation, transmission and distribution) where the value they hold is most desired. Further, energy storage technologies’ feasible renewable energy applications as well as ancillary services applications are closely examined. Efforts to quantify the value that such applications hold to power produces, grid operators and consumers are reviewed and presented. A complete battery energy storage management scheme to maximize potential value that can be brought forth to medium voltage feeders is presented. In general, the potential performance benefits produced by possible energy storage applications include improved system reliability, dynamic stability, enhanced power quality, transmission capacity enhancement and area protection. Hence, a unique control algorithm is introduced. This algorithm comprises three main storage applications. An ancillary services application (voltage support), Energy Time Shift (ETS) and PV Capacity Firming (PVCF) are presented. Designs are tested on EMTP simulation platforms and implemented on a practical feeder.
