Implementation of Maximum Power Point Tracking Algorithm Using Raspberry PI

Renewable energy plays a vital role for the development of a country. Energy can be extracted from a number of ambient conditions like vibration, solar, thermal gradient etc. The maximum power from these systems can be extracted by using MPPT along with power converters. However, conventional maximum power point tracking (MPPT) method for solar cells, are complex and cannot be utilized due to their cost and power requirements. In proposed system the performances of DC-DC converter assisted by MPPT and the performance is characterized by and Perturb and Observe algorithm along with Raspberry Pi controller using boost converter by varying the duty cycle of the boost converter. The main advantages of P&O algorithm are simple in structure, with both stand-alone and grid-connected systems, MPP tracking can be done with very high efficiency.
