OBJECTIVE :-

• Develop a maximum power point tracking (MPPT) algorithm for solar energy system.

• Use a buck boost converter as maximum power point tracker to achieve the system specifications.

COMPONENTS LIST:

• Photovoltaic Module• DC-DC converter• V-I characteristics• Maximum Power Point Tracker.

3

PHOTOVOLTAIC MODULE:-

• Converts solar energy to electrical energy.

4

DC-DC BUCK BOOST CONVERTER:-

• Used to step down or step up of DC voltage.

5

HOW PEAK POWER IS TRACKED?

• By matching of impedance of load and solar module.

• DC-DC converter is used as interface between solar module and load for impedance matching.

SIMULATION:-

METHODS FOR OBTAINING PEAK POWER:-

• PERTURB AND OBSERVE (P & O) ALGORITHM

• INCREMENTAL CONDUCTANCE ALGORITHM

PERTURB AND OBSERVE (P & O) ALGORITHM:-

• P & O method is to modify the operating voltage and current of the PV panel until you obtain the maximum power.

• The tracker operates by periodically incrementing or decrementing the solar array voltage.

• We use only voltage sensor to sense the PV array voltage.

ADVANTAGES:-

• MPPT method can extract maximum available power from the PV module.

• This method can increase the tracking efficiency.

• Simple to implement.

CONCLUSION:-• By using MPPT method,efficiency is increased and maximum power is extracted

from the PV module.

• MPPT offers advantages of good tracking efficiency, response is high and well control for the extracted power.
