Evaluation of the requirements for battery energy storage system to postpone the investment of distribution system

Abstract

This paper proposes the application of the battery energy storage system (BESS) to be installed in the distribution system for the purpose of postponing the investment of the distribution reinforcement in the short term power distribution planning. A study case of the distribution system including the photovoltaic system and the BESS obtained from the Provincial Electricity Authority (PEA) is used to evaluate the requirements of the BESS to be installed in the distribution system by considering four types of loads which are household, small enterprise, industry and other types. It reveals from the study that the installation of the BESS can effectively extend the time of the new distribution line construction.
