Study of Micro Grid Hybrid System of Photovoltaic and Diesel Engine

Abstract

Abstract. Indonesia has abundant potentials of new and renewable energy that can be used for electricity generation, especially in rural areas which have no access for grid electricity yet. The energy resources can be from solar, water, biomass or biofuel. Many villagers still use diesel generators to produce electricity in their villages. It is considered expensive because fuel price in rural areas increases 2-3 times than the normal price due to transportation cost. Hybrid system using renewable energy resources is one of the solutions to produce electricity in affordable cost for rural area. The idea is to combine diesel generators and photovoltaic toproduce electricity. Moreover, the diesel engine fuel can be replaced with biofuel. This study will analyze the hybrid system in a small scale which consists of 1kWp photovoltaic and 3 kW diesel engine. Electric load power will vary. The system is controlled by a single bidirectional inverter whichconverts power from DC to AC and vice versa.

Perancangan Sistem Mikrogrid Cerdas Berbasis Energi Terbarukan Untuk Pabrik Es Nelayan Kapasitas 4 Kw

“…Novitasari, dkk (2016) membuat desain dan optimasi smart grid untuk sistem hibrida PVbiobased diesel engine dengan bahan bakar minyak nabati. Dari eksperimen yang dilakukan terbukti penggunaan bahan bakar nabati tidak berpengaruh terhadap kinerja sistem dan rata-rata efisiensi inverter mencapai 87% [5].…”

“…Kebutuhan listrik di Karimunjawa dicukupi melalui PLTD dengan kapasitas 2,5 MW yang dikelola oleh PLN. Kebutuhan bahan bakar solar PLTD ini mencapai mencapai 4000 liter/hari dan ketersediaannya sangat bergantung pada kondisi cuaca dan gelombang laut [5].…”

“…Sekitar 90% penduduk Karimunjawa hidup dengan mata pencaharian sebagai nelayan tradisional [8]. Es balok sebagai media pendingin ikan hasil tangkapan harus dibeli dari Jepara, sehingga ketersediaannya juga sering terganggu oleh cuaca dan gelombang laut [5].…”
