Abstract

Pemakaian dari pemanfaatan EBT di Indonesia sendiri baru sampai 2,5% dengan tenaga terbesar dari surya. Selinear dengan hal tersebut, menurut Rencana Usaha Penyediaan Tenaga Listrik PLN, potensi energi surya di Provinsi Kalimantan Barat sangat tinggi mencapai 169,634 MW, namun hingga saat ini belum ada pemanfaatan untuk hal tersebut sebab masih mengandalkan pembangkit konvensional berupa (PLTD dan PLTU) yang berkontribusi sebesar 58,85% dari total 680,5 MW. Penambahan kebutuhan listrik Kalbar mengarah pada pembangunan unit pembangkit bertenaga surya yang bersifat intermiten. Saat ini, PLTS yang terintegrasikan pada sistem masih belum ada sebelumnya dan direncanakan akan terjadi penambahan kapasitas pembangkitan PLTS sebesar 169,45 MW dengan Tahun COD 2025 yang tentunya akan memengaruhi stabilitas sistem. Oleh karena itu, dilakukan pemodelan PLTS dan dianalisis dampak penetrasi tinggi PLTS terhadap stabilitas transien sistem kelistrikan Kalbar menggunakan software ETAP versi 22.0.1 dengan memberikan beberapa studi kasus berupa pembangkit lepas, gangguan hubung singkat pada saluran transmisi dan beban besar lepas dengan beragam tingkat penetrasi PLTS. Akan diamati dampak dari setiap studi kasus terhadap nilai critical clearing time, respon sudut rotor, dan respon tegangan bus. Hasil penelitian menunjukkan bahwa dengan adanya PLTS sebesar penetrasi 18% di Kalbar dapat memperbaiki frekuensi sistem tanpa menganggu respon sudut rotor pembangkit dan respon tegangan sistem sebab dengan tambahan daya dari PLTS dan tidak menonaktifkan pembangkit konvensional membuat diversifikasi pembangkit dan memperbesar range cadangan daya serta menjaga inersia di sistem serta kasus intermiten yang membuat beberapa respon tegangan naik.

The utilization of renewable energy in Indonesia itself is only at 2.5%, with the largest source being solar power. In line with this, according to PLN's RUPTL, the solar energy potential in West Kalimantan Province is very high, reaching 169.634 MW. However, until now, there has been no utilization of this potential as it still relies on conventional power plants such as diesel power plants (PLTD) and coal-fired power plants (PLTU), which contribute 58.85% of the total 680.5 MW. The increasing electricity demand in West Kalimantan is leading to the development of solar power plants, which are intermittent in nature. Currently, there are no integrated solar power plants in the system, but an additional solar power generation capacity of 169.45 MW is planned with a COD (Commercial Operation Date) in 2025, which will certainly affect system stability. Therefore, a model of the solar power plant is created and the impact of high solar power penetration on the transient stability of the West Kalimantan power system is analyzed using ETAP software version 22.0.1, considering several case studies such as generator outages, short circuit faults on transmission lines, and large load drops with various levels of solar power penetration. The impact of each case study on the critical clearing time, rotor angle response, and bus voltage response will be observed. The research results show that with 18% solar power penetration in West Kalimantan, the system frequency can be improved without disturbing the generator rotor angle response and system voltage response. This is because the additional power from the solar power plant, without deactivating conventional power plants, diversifies the generation sources, increases the power reserve range, maintains system inertia, and the intermittent cases cause some voltage responses to increase.
