“…Keandalan (Reability) adalah kemampuan sistem tenaga untuk memberikan layanan kepada konsumen dengan tetap menjaga kualitas dan harga listrik pada tingkat yang dapat diterima [10]. Ada empat faktor yang berhubungan dengan keandalan, yaitu probabilitas, bekerja sesuai dengan fungsinya, periode waktu, dan kondisi operasi.…”

Listrik merupakan kebutuhan primer pada saat ini, tak terkecuali di luar pulau Jawa. Pertumbuhan penggunaan konsumsi listrik secara nasional meningkat sehingga diperlukan analisa keandalan suatu pembangkit untuk menjaga kualitas dan harga listrik pada tingkat yang dapat diterima. Salah satu perhitungan keandalan listrik adalah Loss of Load Probability (LOLP). Dimana perhitungan keandalan pada pembangkit PLTU Anggrek 2x25 MW Gorontalo didapatkan nilai LOLP sebesar nilai 37,84 hari/ tahun. Nilai ini masih diatas nilai keandalan standar PLN, hal ini disebabkan pada unit 2 terjadi PO (Planned Outage) dan MO (Maintenance Outage) pada bulan Juni-Juli 2021 yaitu berupa first year inspection pada bulan Juli. Nilai FOR (Force Outage Rate) dihitung berdasarkan data gangguan dari pembangkit di tahun 202, sehingga dilakukan skenario dengan logika fuzzy untuk perbaikan keandalan pada pembangkit. Penelitian ini bertujuan melakukan peramalan beban jangka menengah dengan logika fuzzy menggunakan data beban dan memasukkan faktor-faktor yang mempengaruhi beban listrik. Hasil Penelitian menunjukkan dari skenario 1 didapatkan nilai keandalan 36,86 hari per tahun dan skenario 2 didapatkan 16,16 hari per tahun, skenario 3 dengan nilai 1,54 hari per tahun.

“…In particular, the ramping constraint that exceeds the ramping constraint threshold leads to the loss of the load phenomena [36]. The Loss of Load Probability (LOLP) is defined as the probability of the available generation capacity that is unable to meet the load during a given period [37]. Furthermore, the loss of load event (LLE) in this research can be defined as the moment when the absolute net load power ramp (|NL PR |) exceeded the grid's ramping constraint (GRC) of its conventional generation system.…”

It is widely believed that the incorporation of renewable energy to the current power grid is the way forward in achieving sustainable power generation. Currently, with the reduction of PV prices, many countries have started connecting PV systems into their grid network, hence leading to a sharp increase of the penetration levels of renewable electricity production. This will bring significant change in the load pattern and the ramping requirements of the grid’s conventional generation system due to the varying nature of the renewable energy generation. This significant change affects the stability of the grid frequency because it becomes more challenging for the system operators to maintain the equilibrium between the generation and load. Additionally, this significant change affects the PV system potential hosting capacity of the traditional grid because of the PV system’s curtailment in order to comply with the constraints of the grid’s conventional generation system. In this paper, the net load, grid frequency stability, and grid potential hosting capacity are evaluated in the situation of increasing the penetration level of large-scale PV systems generation into the grid. The results show that the grid operators will face increasingly variable net load patterns and steeper ramping events as the PV system penetration level increases. Additionally, the results show the requirement of having flexibility measures that target each grid constraint as the PV system penetration level increases.
