Abstract

Hybrid power plants using hydropower and solar power are starting to be used and utilized with various technological innovations. Studying the optimization and efficiency of solar panels, including partial shading, dial-axis photovoltaics, and artificial intelligence-based solar panel comparisons, is crucial. Hydroelectric power plants focus on optimizing their AVR (Automatic Voltage Regulator), LFC (Load Frequency Control), and employing artificial intelligence for this purpose. The importance of the solar charge controller (SCC), automatic transfer switch (ATS), and coordination of low voltage disconnect (LVD) has not been taken into consideration in previous studies. The study's findings demonstrate that Pico Hydro energy production and solar panels with SCC, ATS, and LVD coordination efficiently meet all energy needs. This hybrid hydroelectric and solar power plant employs an axial flow turbine with a power output of 2 kW and a 450 Wp solar panel. The output power of the hydroelectric power plant (pico-hydro) is always constant, while the output power of the solar power plant is very fluctuating, with a current output power of 6.34 amperes and a voltage of 28.72 volts in cloudy weather conditions. This study yields energy output that surpasses the load requirements and can effectively fuel energy consumption in the surrounding area. We can use the results of this study to develop other hydropower and solar power plants.
