Abstract—Pico hydro system, a combination of hydro turbine governor, electronic load controller, and generator are outlined as one of the recommended approaches for off-grid power supply option for rural areas communities. In a conventional installation of a hydro system, an electronic load controller with proportional–integral–derivative (PID) is the best alternative to provide power balancing between power generation and load-consuming demand. However, there is always a peak in power demand during the day, but the energy consumption is low at night. This situation caused much energy to be dumped and wasted and a lack of energy management regarding the plant's power stability. Therefore, this research aimed to design fuzzy logic control (FLC) for an energy system that could meet the critical load requirement before being simulated using MATLAB SIMULINK to evaluate the effective utilization of the excess energy. Using Mamdani's methods with 25 membership rules to implement a fuzzy logic-based control system could potentially perform efficient power flow control between scenarios such as discharging, battery backup, and load supply. The result showed that this approach is a better alternative and more efficient system stabilization and energy supply by implementing fuzzy control in surplus power generation from the pico hydro system from 2 sec to 3 sec.
