Maximum Power Angle (MPA) Based Maximum Power Point Tracking (MPPT) Technique for Efficiency Optimization of Solar PV System
Abstract-A novel maximum power angle (MPA) based maximum power point tracking (MPPT) technique is reported. In this technique, a graphical and mathematical approach based maximum power angle determination mechanism is adopted. On the I-V characteristic curve, the angle made from the intersection point of open circuit voltage (VOC) and short circuit current (I) with respect to the voltage (V) axis to the point of maximum power (MPP) is determined using the known parameters of the solar PV module. The proposed MPPT technique is able to minimize the dependency on various voltage and current sensor requirements, thereby the reduced requirement of hardware components. Due to this fact, the implementation cost of this technique is expected low and maintenance needs of such technique based MPPT system would be also minimized.
