THESIS MPPT PERTURB AND OBSERVE

The DMPPT together with battery charge controller is implemented by considering the battery voltage and charging current. 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. 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. By sensing only the output parameters i. 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. Furthermore, to avoid operating voltage from diverging from its locus, a dynamic boundary condition is imposed.

The mathematical validation for the output sensor based MPPT algorithms are presented in this thesis. At the same time, it locates the global peak during partial shading.

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

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

By sensing only the output parameters i. In addition, an improved set of equation is developed to detect the exact position of local peaks under partial shading.

Study of Maximum Power Point Tracking (MPPT) Techniques in a Solar Photovoltaic Array – ethesis

To assess its feasibility, the proposed ideas are simulated using comprehensive PV simulator. The increased energy demand and shortage of fossil reserves motivated researchers to focus on renewable energy sources and photovoltaic PV psrturb 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. Furthermore, the tracking becomes more complicated when the PV array is partially shaded due to the presence of multiple peaks.
