Abstract

Standalone photovoltaic system is a system that does not connect with main grid. So, it is necessary to have a backup supply, considering day and night cycle, where there are no solar radiation at night. Backup supply is often be the grid in the on-grid system, but in an off-grid system, backup supply has to be energy storage system, as in this paper, storage system contains battery and supercapacitor. As stated, standalone photovoltaic with hybrid energy storage system must have its own energy management system. The proposed method in the paper is to use PI controller as the energy management system control. The examined aspect is the voltage and power stability in both battery and supercapacitor. The result compared with the stability characteristics from uncontrolled energy management system. From the result, the PI controlled system is proven to give the better result due to compensation of the load power surplus during the maximum irradiance and increase the battery input by 162.261 W or 69.836% more power to the battery. The load has been optimized, in both maximum irradiance by the decreasing of 178.309 W and half irradiance by the increasing of 15.166 W.
