Feasibility and Optimal Design of Micro-hydro and Photovoltaic Hybrid System in Support to Energy Independent Village

A hybrid system utilizes several energy sources to generate electricity. This paper proposes combination of two renewable energies i.e. micro-hydro and photovoltaic for energy independent village application in Dusun Mergosari, Pesawaran Indah Village, Pesawaran Regency, Lampung Province. Previously, the village was only supplied by one micro-hydro generator through a long feeder line with high voltage drop along the line. In this work, an optimal placement and size of photovoltaic system is identified and studied through software simulation. The obtained results show that installation of a PV system improves grid's performances in terms of lower voltage drop and power losses. About 9.5% to 31% voltage improvements were observed in accordance with PV System installation.
