Abstract :
An efficient Maximum Power Point Tracking (MPPT) method is extremely important to improve the output efficiency and electrical energy quality of a photovoltaic (PV) generating system. The MPPT course is very difficult due to the nonlinear and time-varying output characteristic of a PV system. SMC (sliding mode control) is used to track maximum power point (MPP) of PV system, and the results represent that the SMC have better tracking characteristic as compare with the conventional perturb and observe (PO) method. The RBF neural network is used to improve the SMC in order to increase the electrical energy quality and reduce the output vibration. The simulation results show the reliability of the suggested method, and the output and dynamic characteristics of PV system are significantly improved.
