Participation of Community-Scale Battery Energy Storage in Power System Frequency Regulation

One of the main challenges concerning the transformation towards low carbon power systems is the mismatch between supply and demand, which would become more difficult with increasing the share of the intermittent generation sources i.e. Renewable Energy Sources (RES) in the generation mix. The Community Battery Energy Storage Systems located in the front of the meter (FC-BESS) are attracting increased attention as potential sources of innovation for the sustainable energy transition. However, there is a lack of research that are studied the possible role of FC-BESS in power system frequency regulation where most of the works relying on the Large-scale BESS (L-BESS). Therefore, this research investigates the participation of FC-BESS in the frequency regulation considering low and high renewable penetration scenarios with different overall BESS capacities. The DigSILENT/PowerFactory software was used for implementing the simulation where the modified 14-generator simplified South-Eastern Australian Power System has been used as a test system. The obtained results revealed that FC-BESS provided a better frequency regulation when compared with the L-BESS especially in the high renewable penetration scenario.
