Simulation of Solar Panel Maximum Power Point Tracking Using the Fuzzy Logic Control Method

The use of solar energy has begun to be developed in PLTS, but the photovoltaic module electricity produced is not at maximum output power. To increase the efficiency of the photovoltaic module, Maximum PowerPoint Tracking (MPPT) technology is used. Differences in the level of solar energy irradiation can cause the output power of the solar panels to vary and will not be maximized. Changing temperature and irradiation can be maintained with a maximum voltage of ۴۰Volt and according to what is desired. In this study, MPPT consists of a Boost Converter whose function is to regulate the output voltage, while the algorithm used is the fuzzy logic which works based on Error (E) and Change Error (CE) from changes in the voltage and current of the photovoltaic module. The results showed that after using MPPT when input was given a change in load resistance with irradiation of ۱۰۰۰ W/m۲ and a temperature of ۲۵ ℃ resulted in a difference in power under different conditions compared to a system without MPPT. The power generated without the use of MPPT has a significant change with the results of ۲۲۷.۷W, ۱۱۴.۴W, ۷۶.۵W, ۵۷W, and ۴۵.۵W. Testing the system after installing the MPPT when given an input change in irradiation with a load resistance of ۲۰ Ω and a temperature of ۲۵°C, a more stable power is produced with a value of ۰.۰۰۸W. Then when the input changes to irradiation with a load resistance of ۲۰ Ω and a temperature of ۲۵ ℃, the maximum power produced for each of the highest irrigation is ۷۴۶.۹ W/m۲, ۷۷۹.۴ W/m۲, and ۸۳۹.۴ W/m۲ of ۳۸.۸۸ W, ۴۲.۰۷ W, and ۴۷.۸ W and compared to the system without MPPT only ۲۱.۷۶W, ۲۱.۹۶W and ۲۲.۲۸W.
