Abstract

Potensi energi surya di Indonesia sangat baik, rata-rata 4,80 kWh/m2/hari. Hal ini mendorong masyarakat untuk beralih menggunakan photovoltaic (PV) sebagai sumber energi listrik yang murah dan ramah lingkungan. Pemanfaatan daya luaran dari PV untuk mensuplai beban rumah tangga dilakukan dengan mengubah tegangan dan arus luaran PV dari DC (Direct Current) menjadi AC (Alternating Current) menggunakan inverter. Inverter dapat dioperasikan secara stand-alone (off grid) atau terkoneksi dengan grid (on grid). Inverter yang terkoneksi dengan grid akan terdapat keadaan saat Daya Beban (Pload) > Daya PV (PPV) dan Pload < PPV. Pada keadaan saat Pload > PPV yaitu pada Beban 120 W, 100 W, dan 80 W, maka inverter beroperasi memaksimalkan daya luaran inverter (PInverter) pada daya 64,2 W. Selanjutnya pada saat Pload < PPV yaitu pada Beban di bawah 60 W, maka inverter akan menyalurkan daya sebesar daya yang dibutuhkan oleh beban lokal sehingga tidak terjadi export daya ke Grid. Inverter dioperasikan dengan metode Current Controlled Voltage Source Inverter (CC-VSI) dan menggunakan Teknik Hysterisis Current Control (HCC). Dengan mengatur besarnya Arus Referensi (Iref) yang diinputkan, maka PInverter dapat diatur sebagai mode Maksimum Power (MPPT Mode) atau Load Follower Mode. =============================================================================================== The potential of solar energy in Indonesia is very good, averaging 4.80 kWh / m2 / day. This encourages people to switch to using photovoltaic (PV) as a cheap and environmentally friendly source of electricity.The use ofPV power to supply local loads is available with changing PVs voltageand current from DC (Direct Current) to AC (Alternating Curent) using anInverter.Inverter can be operatingstand-alone (off grid) or grid connected (on grid). Inverter which connected to grid will have condition when Load Power (Pload)> PV Power (PPV)and Pload< PPV. At the moment Pload> PPVis at 120 W, 100 W, and 80 W, then the Inverter is operating to get the maximum output power of Inverter (Pinverter)at 64,2 W. Furthermore, when Pload< PPVis at Power Loads under 60 W, the inverter will deliver as many as the power needed by the local loads so ther is no power export to grid. Inveter is operated using Current ControlledVoltage Source Iverter (cc-VSI)method and uses Hysterisis current control (HCC)technique. By setting the Reference Current (Iref), P inverter can be set as Maximum Power Mode (MPPT)or Load Follower Mode
