Implementation of Incremental Conductance Method for Maximum Power Point Tracking (MPPT) Solar Photovoltaic in Renewable Energy Laboratory State Polytechnic of Malang

Photovoltaic (PV) is an unlimited and popular resource today because it does not require high maintenance costs and is emission free. Photovoltaic modules are affected by changes in sunlight intensity, so a method is needed to find the maximum power point of the photovoltaic module. Maximum Power Point Tracker (MPPT) is one of the methods used to find the maximum power point on a Photovoltaic module. By connecting current and voltage sensors on the input side of the converter to be read by the microcontroller and connected to the buck converter circuit and applying the incremental conductance method to the microcontroller to regulate the output voltage of the buck converter by adjusting the duty cycle on the PWM generated by the microcontroller. The results of the converter are then analyzed using a load in the form of an accumulator. On the output side of the buck converter, current and voltage sensors will also be connected to determine the output of the buck converter itself. The Incremental Conductance method has the advantage of dealing with rapid changes in light intensity and shadow fluctuations on solar panels. By comparing power gradients, this method can efficiently track the MPP and optimize the power generated by the solar panels. After testing and analysis, the incremental conductance method provides an efficiency maximum until 99%, as evidenced by a comparison of the power values. By using MPPT, the output power of solar panels can be optimized at 42.24 Watt with an accumulator load of 12 volts
