THESIS MPPT PERTURB AND OBSERVE

The DMPPT together with battery charge controller is implemented by considering the battery voltage and charging current. Furthermore, the tracking becomes more complicated when the PV array is partially shaded due to the presence of multiple peaks. The objectives of peak power tracking and battery charge controller are achieved with less number of sensors with the proposed method. By sensing only the output parameters i. 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. The increased energy demand and shortage of fossil reserves motivated researchers to focus on renewable energy sources and photovoltaic PV power generation is evolving as one of the most remarkable renewable energy sources because of its benefits like eco-friendly nature, less maintenance, and no noise. Photovoltaic module mismatching and non-uniform insolation conditions are the major drawbacks of the PV systems.

The objectives of peak power tracking and battery charge controller are achieved with less number of sensors with the proposed method. 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. The distributed maximum power point tracking DMPPT method is an effective solution to mitigate these drawbacks but, the DMPPT with conventional algorithms requires more number of sensors to implement.

Furthermore, to avoid operating voltage from diverging from its locus, a dynamic boundary condition is imposed.

To assess its feasibility, the proposed ideas are simulated using comprehensive PV simulator. The Efficiency of the PV system primarily depends on the operating point on the characteristic curve of the PV module. The DMPPT together with battery charge controller is implemented by considering the battery voltage and charging current.

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. The PV systems generally contain a battery, where the output voltage and current are to be measured for the implementation of battery charge controller.

For partial shading, an effective checking mechanism to precisely detect partial shading occurrence is suggested.
