Abstract


Abstract— The design of the inverter control system aims to regulate active power and reactive power flows from the batteries through the three-phase inverter. Reference power generated manually to compensate the active and reactive power required by microgrid. Modelling done by the transformation clarke-park to design close loop system with PI (Proportional Integral) control so that the current flows in the inverter is maintained at the reference value. PLL (Phase Locked Loop) is used to synchronize inverter and grid. The simulation result shows that the system can work very well and the voltage or frequency of microgrid maintained under normal conditions.

Intisari— Perancangan pada sistem kendali inverter ini bertujuan untuk mengatur daya aktif dan daya reaktif yang mengalir dari baterai melalui inverter tiga fase. Daya referensi dibangkitkan secara manual untuk mengkompensasi daya aktif dan reaktif yang diperlukan oleh mikrogrid. Pemodelan dilakukan berdasarkan transformasi clarke-park untuk merancang sistem close loop dengan Pengendalian PI (Proporsional Integral) sehingga arus yang mengalir pada inverter dipertahankan pada nilai referensinya. PLL (Phase Locked Loop) dipergunakan agar inverter selalu dalam kondisi sinkron dengan grid. Hasil Simulasi menunjukkan bahwa sistem dapat beroperasi dengan baik sehingga tegangan maupun frekuensi dari mikrogrid dapat dipertahankan dalam kondisi normal.

Kata Kunci— penyimpan energi listrik, transformasi clarkepark, PLL, pengendalian PI.
