Efficient Variable Step Size Single Current Sensor Maximum Power Point Tracking for PV Systems

抄録

The issue of maximum power point tracking (MPPT) has been addressed in different ways in the literature. MPPT based on single variable are recently has a great attention due to its simplicity and ease in implementation. However the main drawbacks of these strategies their operation with fixed step size which ensure a steady state oscillations around the maximum power point and slow dynamic response. In this paper a modified variable step size based on single current sensor MPPT has been proposed.
