Efficiency improvement of photovolatic by using maximum power point tracking based on a new fuzzy logic controller

Abstract

Maximum power point tracking (MPPT) is a technique to maximize the power output of photovoltaic (PV). Therefore, to achieve higher PV efficiency, the development of MPPT control algorithm is necessary. Recently, it was revealed that fuzzy logic controller (FLC) is better than other control algorithms and is possible toe developed. This study fabricated and implemented MPPT based on the proposed a new FLC. Input Calculator (IC) via sensors reads current and voltage of PV and generates the comparison of voltage and current of PV, then IC output becomes fuzzy algorithm input. Fuzzy algorithm produces duty cycle that drives synchronous buck converter. The result showed that MPPT system with proposed FLC method has 99.1% efficiency while MPPT system with P&O method has 95.5% efficiency. From the obtained result, it can be concluded that the MPPT based on the proposed FLC can increase the overall efficiency of the system to 99.3%.

“…As a result, the PV systems' energy yield was drastically reduced. The various MPPT algorithms are discussed in this study along with their benefits and drawbacks for uniform insolation and partial shading circumstances [19][20][21][22][23][24][25][26]. Effendy et al [21] concluded that the MPPT based on a new FLC can increase the overall efficiency of the system to 3%.…”
