Abstract

Penggunaan distributed generator (DG) yang terhubung off grid seperti generator diesel-photovoltaic (PV)-baterai perlu dilakukan kontrol strategi yang baik. Generator diesel pada sistem hibrida bertindak sebagai pengatur frekuensi dengan menggunakan metode kontrol droop. PV dapat menyuplai dengan daya maksimum dan memiliki karakteristik frequency shift power control (FSPC) yaitu PV mengurangi daya outputnya berdasarkan frekuensi sistem. Ketika frekuensi sistem mencapai hingga 1 Hz di atas frekuensi nominal (f+1), daya output PV akan maksimum. Adapun bila frekuensi sistem melebihi (f+1), FSPC akan aktif dan PV akan mengurangi daya output hingga PV tidak menyuplai daya saat frekuensi 2 Hz di atas frekuensi nominal (f+2). Melalui pembacaan frekuensi sistem, pada penelitian ini sistem hibrida akan memadukan sistem kontrol droop dan menganalisis pengaruh FSPC untuk mencapai pembagian daya. Konfigurasi sistem hibrida ini akan bertemu di AC coupling, karenanya PV dan baterai memiliki inverter masing-masing. PV inverter dan baterai inverter dimodelkan dengan average model inverter. Hasil menunjukkan kontrol droop dan FSPC dapat bekerjasama melalui pembacaan frekuensi. FSPC mampu mengontrol daya output PV pada daya 0-85 kW (daya nominal) pada rentang frekuensi 50,35 Hz-52,35 Hz sesuai dengan kontrol droop yang diinginkan. =====================================================================================================================================
The use of distributed generators (DG) connected off grid such as diesel generator-photovoltaic (PV)-battery requires a good control strategy. Diesel generator in hybrid system acts as frequency regulator using the droop control method. PV can supply maximum power and has frequency shift power control (FSPC) characteristic, it means PV reduces its output power based on the system frequency. When the system frequency reaches up to 1 Hz above the nominal frequency (f+1), the PV output power will be maximum. Meanwhile, if the system frequency exceeds (f+1), FSPC will be active and the PV will reduce the output power until PV does not supply power when the frequency is 2 Hz above the nominal frequency (f+2). By reading the system frequency, in this research the hybrid system will combine the droop control and analyze the impact of FSPC to achieve accurate power sharing. This system configuration will meet at AC coupling, therefore PV and battery have their own inverter. The PV and battery inverter are modelled with the average model inverter. The result show that droop control and FSPC can work together through frequency reading. FSPC can control PV output power at 0 - 85 kW (nominal power) over a frequency range of 50.35 Hz - 52.35 Hz, consistent with the desired droop control.
