This paper presents the first comparative analysis of frequency support provided by a large-scale bulk energy storage system (ESS) against distributed ESS in a large meshed network. In IEEE 16 machine network, 30% of synchronous generation is replaced by renewables (RES). The analysis is further extended to investigate the effect of increased penetration of RES and reduction in inertia by decreasing synchronous generation at low network loading conditions for both types of ESS arrangements.
