Abstract

Keandalan sistem dan tingkat efisiensi yang tinggi pada saluran distribusi energi listrik menjadi aspek yang sangat vital bagi perkembangan energi pada beberapa tahun belakang. Pemanfaatan energi terbarukan seperti energi surya pada saluran distribusi memiliki peran penting dalam perkembangan energi ramah lingkungan bagi masyarakat. Sebuah sistem distribusi menggunakan energy storage berbasis BESS (battery energy storage system) diusulkan dengan kelebihan dalam hal keandalan dan kualitas tegangan yang dihasilkan. Pada penelitian ini akan dilakukan simulasi penggunaan BESS pada saluran distribusi yang dikombinasikan dengan penetrasi dari sumber energi terbarukan berupa PV. Simulasi dilakukan pada sistem radial IEEE 33 bus yang sudah dimodifikasi dengan beban dinamis selama 24 jam pada tiga skenario yang berbeda, yaitu sistem tanpa PV dan BESS, sistem dengan PV tanpa BESS, dan sistem dengan PV dan BESS. Pada skenario pertama, didapatkan hasil berupa drop tegangan dan rugi-rugi daya yang cukup tinggi. Pada skenario kedua, drop tegangan dan rugi-rugi daya berhasil diturunkan tetapi masih terjadi drop tegangan ketika terjadi beban puncak. Pada skenario ketiga, drop tegangan pada kondisi beban puncak berhasil diatasi sehingga kualitas tegangan menjadi lebih baik dan tidak melewati standart yang telah ditetapkan. Rugi daya aktif menurun sebesar 63,4 persen dan rugi daya reaktif menurun sebesar 28,4 persen. Dari segi biaya, sistem dengan PV dan BESS membutuhkan biaya yang paling optimal karena tidak dikenakan biaya denda akibat deviasi tegangan.

The reliability and high efficiency of electrical energy distribution lines have become crucial aspects of energy development in recent years. The integration of renewable energy, such as solar energy, into distribution lines plays a significant role in promoting environmentally friendly energy for society. A distribution system utilizing energy storage based on Battery Energy Storage Systems (BESS) is proposed, offering advantages in terms of reliability and the quality of the produced voltage. This study will simulate the application of BESS on distribution lines combined with the penetration of renewable energy sources in the form of photovoltaic (PV) systems. Simulations were conducted on a modified IEEE 33-bus radial system with dynamic loads over a 24-hour period across three different scenarios: a system without PV and BESS, a system with PV without BESS, and a system with both PV and BESS. In the first scenario, the results indicated significant voltage drops and power losses. In the second scenario, voltage drops and power losses were successfully reduced, although voltage drops still occurred during peak load conditions. In the third scenario, the voltage drop during peak load conditions was successfully mitigated, resulting in improved voltage quality that remained within predetermined standards. Active power losses decreased by 63.4%, and reactive power losses decreased by 28.4%. From a cost perspective, the system incorporating both PV and BESS was the most optimal as it avoided penalty fees due to voltage deviations.
