| Summary: | Battery Energy Storage Systems (BESS) have been widely used in power
system operation. We consider using a BESS simultaneously for peak shaving and
frequency regulation will make a better power system operation. BESS will
discharge at peak demand to compensate the high cost of generation plant, and
also we need to control frequency regulation because abnormal frequency can
damage power system equipment. This paper deals with a methodology to
optimizing BESS for both application. The optimization based on consideration of
size and location of BESS. BESS modeling are based on total cost production,
includes investment cost and all operational costs, NPV and IRR. To determine
the optimal BESS capacity also consider Depth of Discharge (DoD), efficiency,
duration charge and discharge. While, location of BESS can determine based on
load factor. The results will be compared between system that uses BESS with
system without BESS. The installation of BESS with a capacity of 232 MWh and
power rating of 39,67 MW in Bali subsystem was abel to improves the voltage
profile.
