THESIS MPPT PERTURB AND OBSERVE

Universiti Teknologi Malaysia Institutional Repository. The objectives of peak power tracking and battery charge controller are achieved with less number of sensors with the proposed method. The PV systems generally contain a battery, where the output voltage and current are to be measured for the implementation of battery charge controller. Furthermore, to avoid operating voltage from diverging from its locus, a dynamic boundary condition is imposed. This thesis is focussed on improvement of tracking performance of maximum power point tracking MPPT algorithms and development of MPPT and battery charge controller algorithms with minimum number of sensors to reduce the overall cost of the PV systems. The DMPPT together with battery charge controller is implemented by considering the battery voltage and charging current.

At the same time, it locates the global peak during partial shading.

The objectives of peak power tracking and battery charge controller are achieved with less number of sensors with the proposed method. 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. For partial shading, an effective checking mechanism to precisely detect partial shading occurrence is suggested.

  EWORKSHOP PROBLEM SOLVING POSTERS

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 DMPPT together with battery charge controller is implemented by considering the battery voltage and charging current. To assess its feasibility, the proposed ideas are simulated using comprehensive PV simulator.

This thesis is focussed on improvement of thhesis performance of maximum power point tracking MPPT algorithms and development of MPPT and battery charge controller algorithms with minimum number of sensors to reduce the overall cost of the PV systems.

Furthermore, the tracking becomes more complicated when the PV array is partially shaded due to the presence of multiple peaks. For partial shading, an obseeve checking mechanism to precisely detect partial shading occurrence is suggested.
