THESIS MPPT PERTURB AND OBSERVE

The PV systems generally contain a battery, where the output voltage and current are to be measured for the implementation of battery charge controller. The objectives of peak power tracking and battery charge controller are achieved with less number of sensors with the proposed method. The tracking performance of the output parameter based MPPT algorithm for solar insolation and load variation is investigated in this thesis. By sensing only the output parameters i. To assess its feasibility, the proposed ideas are simulated using comprehensive PV simulator. Photovoltaic module mismatching and non-uniform insolation conditions are the major drawbacks of the PV systems.

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. More information and software credits.

The tracking performance of the output parameter based MPPT algorithm for solar insolation and load variation is investigated in this thesis.

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

Development of Efficient MPPT Algorithms with Reduced Number of Sensors for Photovoltaic Systems

The PV systems generally contain a battery, where the output voltage and current are to be measured for the implementation of battery charge controller. In addition, an improved set of equation is developed to detect the exact position of local peaks under partial shading. 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 mppy cost of the PV systems.

The Efficiency of the PV system primarily depends on the operating point on the characteristic curve of the PV module. Furthermore, the tracking becomes more complicated when the PV array is qnd shaded due to the presence of multiple peaks.
