Abstract
The use of renewable energy sources (RES), especially photovoltaic (PV), to meet the demand of electrical energy has been getting a great deal of attention as an alternative solution to electrical energy deficit problems. RES are being applied in power systems in a variety of configurations including microgrid systems. One of the characteristics of a microgrid is capability to supplying power to grid when there is an excess power to supply local load. This research examines the chances of saving power consumption from grid using power converters grid tie inverter (GTI) in a microgrid configuration. The test is done by using a zero load and power distribution methods. Test results show grid tie GTI capable of supplying electrical power to grid up to 98% of the input power converter. In the microgrid configuration power usage from grid can be reduced up to 91%, which should be supplied from the grid to load.
Bahasa Abstract
Pengembangan Jaringan Listrik Mikro Menggunakan Grid Tie Inverter (GTI). Penggunaan sumber energi terbarukan (SET), khususnya photovoltaic (PV), untuk memenuhi kebetuhan energi listrik semakin menjadi perhatian sebagai salah satu alternatif solusi permasalahan defisit energi listrik. Penerapan SET pada sistem pembangkit listrik dilakukan dalam berbagai konfigurasi antara lain sistem jaringan listrik mikro/JLM (microgrid). Salah satu karakteristik JLM antara lain mampu mensuplai daya ke grid jika terjadi kelebihan daya untuk mensuplai beban lokal. Penelitian ini mengkaji peluang penghematan penggunaan daya listrik dari grid/PLN menggunakan konverter daya grid tie inverter (GTI) dalam konfigurasi JLM. Pengujian dilakukan dengan menggunakan metode beban nol dan distribusi daya. Hasil pengujian menunjukkan konverter daya GTI mampu mensuplai daya listrik ke jaringan hingga 98% dari masukan daya konverter. Pada konfigurasi JLM penggunaan daya dari grid/PLN dapat dikurangi hingga 91% dari daya yang seharusnya disuplai grid/PLN ke beban.
