Renewable Energy Power System for Indonesia Future Islands

Abstraksi

Providing reliable and sustainable energy supply with appropriate environmental considerations to future Indonesia remote islands, is the main aim of this project. The need for an appropriate and environmentally-friendly solution to the lack of energy and water supplies in remote islands are vital for ensuring sustainable development. In this research project, evaluation was carried out on a prototype novel modular AC coupling minigrid hybrid power and water supply system (MHPWS) with laboratory scale experiments and attempted project implementation in two case studies: Republic of Maldives and Indonesia. The system proposed consists of: renewable energy generators, such as Photovoltaic (PV) and wind turbine; diesel generator as back-up with power conditioning and energy storage system; and reverse osmosis desalination plant to produce clean water supply as deferrable load. This covers theoretical analysis, modelling, simulation and experimental works on a minigrid hybrid power system implementing a voltage and current controlled voltage source inverter. Case studies of real conditions in remote areas that have experienced natural disasters were undertaken - one in the Maldives (Tsunami 2004) and the other in Indonesia (Earthquake 2006). The experimental works on the prototype of a 5 kVA minigrid inverter and a reverse osmosis desalination plant as a deferrable load rated at 5.5 kWh/day were conducted in the industrial partner precinct, Regen Power Pty Ltd, and in Curtin University Australia premises, to verify the idea of providing power and water supplies to remote areas.
