A Research and Improvement on a Maximum Power Point Tracking Method for PV System under Partially Shaded Conditions

AbstractThe output characteristic of Photovoltaic cells is nonlinear. When PV module is under partially shaded conditions, the output power-voltage curve contains multi-local maximum points. This paper presents a new complex algorithm to track the maximum power point (MPP) in complex conditions. This algorithm is used in photovoltaic energy system simulation model what established in PROTEUS simulation platform, and proved that it can track maximum power point of PV module more quickly and accurately than other algorithms
