A Voltage Sensitivity Framework for Optimal Allocation of Battery Energy Storage Systems

Abstract

Battery energy storage systems (BESSs) play a pivotal role to mitigate the power quality challenges associated with the evolution of the modern of distribution network. Nevertheless, optimal allocation of BESS is pertinent to appropriately utilize and maintain their techno-economic significance. This paper presents a framework based on voltage sensitivity approach to establish an optimal BESS allocation strategy and subsequently, effectively extract their support towards appropriate energy utilization. The proposed methodology is validated on an IEEE 8 bus distribution network. The results obtained demonstrates an improved voltage profile with the identified BESS allocation and additionally lower overall system line losses.
