Abstract
Microgrid systems are supplied from solar photovoltaic (PV) as an input grid-tie inverter (GTI). In this research, GTI used is a grid-tie micro-inverter 1000 watt. GTI is a power converter direct current (DC) into alternating current (AC) and can operate when connected to electricity grid utility. GTI output connected to a local load such as incandescent lamps, CFL lamps, small refrigerators, TV and fans. The problem with the microgrid system with GTI is GTI unable to operate to generate power if it does not detect the reference voltage of grid utility (islanding condition). This research proposes the idea to replace electricity grid utility with a battery system from wind power generation when grid utility is interrupted or blackout. The research experiment conducted in a renewable energy laboratory of Faculty of Engineering, University of Mataram. The addition of controlled renewable energy sources such as small wind turbines can improve the performance of GTI to optimize power generated on the microgrid system, when electricity from power grid utility is interrupted or outages. The variables measured in GTI performance testing on the microgrid system are voltage, current, and THD. The value of voltage generated by GTI to 2 conditions of test carried out is still within the allowable standard limit of ± 10% of nominal voltage (220 Volts). Similarly, the THD value of the result is still below the specified standard (5%).
