Abstract
Pada sistem kelistrikan di Pulau Tomia, Pembangkit Listrik Tenaga Surya (PLTS) dikoneksikan dengan baterai dan Pembangkit Listrik Tenaga Diesel (PLTD) sehingga membentuk suatu sistem hybrid. Kinerja PLTS sangat bergantung pada radiasi matahari dan cuaca. Hal tersebut menyebabkan daya keluaran PLTS selalu fluktuatif. Fluktuasi PLTS akan diredam oleh baterai agar tidak terlalu memengaruhi kinerja PLTD. Namun, dalam kenyataanya baterai masih belum mampu meredam fluktuasi PLTS sehingga menghasilkan daya ekspor yang fluktuatif. Dengan adanya hal tersebut maka dilakukan analisis kestabilan transien untuk mengetahui respon PLTD terhadap sistem saat terjadi fluktuasi. Setelah simulasi dilakukan, terdapat tiga kasus yang tidak boleh terjadi. Pertama, saat PLTS mengeluarkan daya 100% dari kapasitasnya tanpa adanya baterai yang beroperasi menyebabkan hilangnya sinkronisme PLTD terhadap sistem dan terjadinya reverse power pada PLTD. Kedua, saat PLTS beroperasi sebesar 100% dengan adanya baterai menyebabkan PLTD bekerja 24% dari kapasitasnya. Hal tersebut tidak sesuai dengan kapasitas minimum yang dianjurkan, yaitu 30%. Ketiga, saat baterai discharging sebesar 100% dari kapasitasnya, PLTD menyalurkan daya sebasar 26%.

In the grid system of Tomia Island, Solar Power Plant (PLTS) are connected with battery and Diesel Power Plant (PLTD) to form a hybrid system. The performance of PLTS is very dependent on solar radiation and weather. So that, the power output always fluctuates. PLTS fluctuations will be damped by the battery so as not to affect the performance of PLTD too much. However, in fact the battery still not able to reduce the fluctuatuions in the PLTS so that produce fluctuations export power. Cause of that, transient stability is needed to determine the PLTD response to the system when fluctuations occur. After the simulation is done, there are three cases that may occur. First, when solar power plants emit 100% of their capacity without the existence of a battery that operates it causes PLTD loss synchronism to the system and reverse power in the PLTD. Second, when PLTS operates at 100% with presence of batteries, PLTD works 24% of its capacity. This is not in accordance with the recommended capacity, which is 30%. Third, when the battery discharging is 100% of its capacity, PLTD delivers 26% of the power.
