THESIS MPPT PERTURB AND OBSERVE

Furthermore, the tracking becomes more complicated when the PV array is partially shaded due to the presence of multiple peaks. To improve the tracking performance as well as to reduce the cost, a single voltage-sensor-based adaptive MPPT technique employing a variable scaling factor is developed. For partial shading, an effective checking mechanism to precisely detect partial shading occurrence is suggested. The Efficiency of the PV system primarily depends on the operating point on the characteristic curve of the PV module. The mathematical validation for the output sensor based MPPT algorithms are presented in this thesis. The objectives of peak power tracking and battery charge controller are achieved with less number of sensors with the proposed method. Universiti Teknologi Malaysia Institutional Repository.

For a systematic design of adaptive technique, a voltage reference control technique with the association of PI-controller is introduced for the implementation of input voltage-sensor-based MPPT algorithm. For partial shading, an effective checking mechanism to precisely detect partial shading occurrence is suggested. Photovoltaic module mismatching and non-uniform insolation conditions are the major drawbacks of the PV systems. Furthermore, to avoid operating voltage from diverging from its locus, a dynamic boundary condition is imposed. The tracking performance of the output parameter based MPPT algorithm for solar insolation and load variation is investigated in this thesis. More information and software credits.
