A Review on Perturb and Observe Maximum Power Point Tracking in Photovoltaic System
Abstract: Solar energy is
becoming popular and has drawn lots of attention from researchers nowadays. However,
the output power of the photovoltaic (PV) arrays varies with solar irradiation
and temperature, which affect the efficiency of PV arrays. Therefore, Maximum
Power Point Tracking (MPPT) controltechnique is used to extract the maximum
available power from the PV arrays. Perturb and Observe (P&O)algorithm is
one of the favorite techniques frequently used due to its simplicity and low
cost. Yet, the conventional P&O algorithm has several drawbacks, which
leads to power loss and lack of efficiency. This paper presents comparison of
the basic P&O algorithm with the modified P&O algorithm used for
partial shading condition in terms of complexity, accuracy, cost, and basic
concept of each method.
