TỐI ƯU KÍCH CỠ CỦA HỆ THỐNG PIN LƯU TRỮ NĂNG LƯỢNG SỬ DỤNG TỐI ƯU BẦY ĐÀN CHO MICROGRID

Tóm tắt

Nowadays, the rapid penetration of renewable energy sources causes
instability in the grids, especially in the microgrids. Battery Energy Storage
System (BESS) with an optimum size when integrating into a microgrid can
prevent it from instability as well as system collapse. The installation of BESS
whose size is arbitrary or not optimal might result in higher cost, system losses,
and larger BESS capacity. Therefore, this research provides a novel technique for
determining an optimal BESS size at a low total BESS cost based on particle
swarm optimization (PSO) using MATLAB in a standalone microgrid. The Loss of
Power Supply Probability (LPSP), Loss of Load Expected (LOLE), and Loss of
Energy Expected (LOEE) indices are also considered in this paper. The result
reveals that with the optimum BESS size achieved, it can dramatically improve
the stability of the microgrid and simultaneously maintain a high level of
economic viability.
