A new approach to maximum power point tracking for sudden changes in irradiance in photovoltaic systems

Background/Objective: This paper presents a new digital control approach to track the Maximum Power Point (MPPT) for Potovoltaic (PV) systems. A photovoltaic power generation system requires an effective controller to overcome sudden changes to irradiance and to maximize its efficiency. Methods/Stat...
