Novel Lyapunov-based rapid and ripple-free MPPT using a robust model reference adaptive controller for solar PV system

Abstract The technological, economic, and environmental benefits of photovoltaic (PV) systems have led to their widespread adoption in recent years as a source electricity generation. However, precisely identifying PV system's maximum power point (MPP) under normal shaded weather conditions is crucial conserving the generated power. One biggest concerns with system existence partial shading, which produces multiple peaks P–V characteristic curve. In these circumstances, classical tracking (MPPT) approaches are prone getting stuck on local failing follow global (GMPP). To overcome such obstacles, new Lyapunov-based Robust Model Reference Adaptive Controller (LRMRAC) designed implemented reach GMPP rapidly ripple-free. proposed controller also achieves MPP accurately slow, abrupt rapid changes radiation, temperature load profile. Simulation OPAL-RT real-time simulators various scenarios performed verify superiority approach over other state-of-the-art methods, i.e., ANFIS, INC, VSPO, P&O. accomplished less than 3.8 ms 10 ms, respectively. Based results presented, LRMRAC appears be promising technique for MPPT system.
