It is necessary to track the maximum power point(MPP) of the PV array rapidly and accurately and it can increase the output power of photovoltaic array.This article summarizes the methods of Maximum Power Point Tracking(MPPT),including the Perturb-and-observation Method and Incremental Conductance Method and points out the limitations and notes of those two methods.This paper divides a number of different techniques for MPPT of PV arrays into four groups by the control theory and development process of MPPT,analyses their merits and demerits and compares methods with others.The main aspects of the MPPT techniques to be taken into consideration are highlighted in the subsequent subsection.Finally,some feasible thoughts with new technologies for solving problem are discussed and its study direction in the future is also looked ahead.It is also indicated that MPPT in the single-stage inverter for PV systems has become a hot research area at home and abroad.
