A STUDY ON THE INTEGRATION OF BATERY ENERGY STORAGE SYSTEM (BESS) INTO THE ELECTRIC POWER SYSTEM OF PHU QUY ISLAND

Abstract

The reality of operating the electric power system of Phu Quy island district,
Bình Thuan province shows that although the invested wind power is relatively
high compared to the load demand, operation and the stability of the system still
largely depend on diesel generators. Low penetration rate of renewable energy
into the system results in high electricity production costs. This paper acquires
operation data of the entire electric power system for one year and performs
simulation and calculations in MATLAB to study the feasibility of integrating a
battery energy storage system (BESS) to the Phu Quy's existing power system.
Objectives of this study are as (1): Introduce an operating method which can
harvest maximum clean energy from renewable sources and (2) implement a
quantitative calculation of the effectiveness of BESS integration into the Phu Quy
island’s grid
