Abstract
Peningkatan penetrasi Pembangkit Listrik Tenaga Surya (PLTS) menyebabkan berkurangnya inersia sistem tenaga sehingga kestabilan frekuensi menjadi lebih rentan terhadap gangguan, khususnya pada sistem terisolasi seperti Pulau Bawean. Penelitian ini bertujuan menganalisis pengaruh penerapan Speed Droop Control (SDC) pada Battery Energy Storage System (BESS) terhadap kestabilan transien sistem kelistrikan Pulau Bawean serta menentukan nilai droop yang optimal. Pemodelan dan simulasi dilakukan menggunakan DIgSILENT PowerFactory pada sistem yang telah tervalidasi dengan tingkat kesalahan di bawah 5%. Analisis dilakukan melalui simulasi gangguan generator isochronous trip dan feeder Kota trip dengan membandingkan kinerja BESS Grid Following (GFL) tanpa SDC dan BESS Grid Forming (GFM) dengan SDC pada variasi droop 3%, 4%, 5%, 6%, dan 7%. Hasil penelitian menunjukkan bahwa BESS GFM dengan SDC memberikan respons frekuensi yang lebih baik dibandingkan BESS GFL. Pada skenario generator isochronous trip, BESS GFL menghasilkan frekuensi nadir sebesar 49,55 Hz dengan settling time 8,212 s, sedangkan BESS GFM dengan droop 3% menghasilkan frekuensi nadir tertinggi sebesar 49,86 Hz dan settling time tercepat sebesar 3,682 s. Seiring meningkatnya nilai droop hingga 7%, frekuensi nadir menurun menjadi 49,71 Hz dan settling time meningkat menjadi 7,371 s. Berdasarkan hasil tersebut, nilai droop 3% direkomendasikan sebagai parameter optimal untuk meningkatkan kestabilan transien sistem kelistrikan Pulau Bawean.

The increasing penetration of Photovoltaic (PV) power plants has reduced the inertia of power systems, making frequency stability more vulnerable to disturbances, particularly in isolated systems such as the Bawean Island power system. This study aims to analyze the effect of implementing Speed Droop Control (SDC) on a Battery Energy Storage System (BESS) to improve the transient stability of the Bawean Island power system and to determine the optimal droop setting. The system was modeled and simulated using DIgSILENT PowerFactory, with the developed model validated to achieve an error of less than 5%. The analysis was conducted under two disturbance scenarios, namely generator isochronous trip and Kota feeder trip, by comparing the performance of Grid Following (GFL) BESS without SDC and Grid Forming (GFM) BESS with SDC at droop settings of 3%, 4%, 5%, 6%, and 7%. The simulation results show that GFM BESS with SDC provides superior frequency response compared to GFL BESS. Under the generator isochronous trip scenario, GFL BESS achieved a frequency nadir of 49.55 Hz with a settling time of 8.212 s, whereas GFM BESS with a 3% droop achieved the highest frequency nadir of 49.86 Hz and the fastest settling time of 3.682 s. As the droop value increased to 7%, the frequency nadir decreased to 49.71 Hz while the settling time increased to 7.371 s. Therefore, a 3% droop setting is recommended as the optimal control parameter for improving the transient stability of the Bawean Island power system.
