Impact of Inverter to Hybrid Power Generation: Wind Turbine and Solar Cell

In recent times, the use of Renewable Energy Sources (RES) has become a viable alternative to supply electrical energy in island regions. Ensuring energy supply security is a key factor for sustainable development in these areas. Each island region possesses unique geographical characteristics and environmental conditions. However, many island regions still rely heavily on electrical energy supplied by diesel power plants (DPP). Despite this reliance, RES has not yet been able to become the primary energy source to replace DPP. Based on these issues, the author aims to analyse the generation of solar and wind renewable energy through a hybrid power plant. This study involves research using a static wind turbine model in the form of a fan and a micro-scale Solar Power Plant (SPP). On the wind power side, the output is connected to Battery Control Unit (BCU) with Maximum Power Point Tracker (MPPT) to charge the battery, which is then channelled to an inverter and connected to an AC bus. Meanwhile, the output of the SPP is directly connected to a Grid Tie Inverter, which is then connected to the AC bus. During the testing phase, both power generations were successfully to supply loads of 20, 25, 30, 35, 40, and 45 Watts. However, when 40 and 45 load were applied, the battery disliked rapidly due battery control unit to slow response of backed up by the MPPT for recharging.
