Abstract


Dalam makalah ini disajikan hasil penelitian untuk sistem penyimpan energi udara tekan skala kecil yang diupayakan untuk beroperasi pada efisiensi maksimumnya. Berbeda dengan yang dilakukan pada penelitian sebelumnya yang menggunakan buck converter pada sisi keluaran generatornya, pada makalah ini digunakan sebuah boost converter. Penggunaan boost converter ini dimaksudkan agar turbin-generator dapat dioperasikan dengan kecepatan yang cukup rendah tapi tetap dapat menghasilkan tegangan keluaran sesuai dengan tegangan nominal beban, yaitu 12 volt. Strategi ini dipilih karena karakteristik turbin memperlihatkan efisiensi yang lebih tinggi jika turbin dioperasikan dengan kecepatan yang lebih rendah. Dalam makalah ini, pencarian titik efisiensi maksimum dilakukan dengan perturb and observe (P&O). Hasil percobaan menunjukkan bahwa penempatan boost converter ini efektif untuk mendapatkan titik pengoperasian dengan efisiensi maksimun jika daya beban relatif cukup kecil terhadap daya nominal turbin-generator, yaitu di bawah 50%.
