Design and Implementation of Perturb and Observation Maximum Power point Transfer (MPPT) algorithm for Photovoltaic system
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 5
Abstract
The electricity crisis in India is still at large with over 300 million people still having no means to electricity. According to FICCI power shortages costs around 68 million in GDP. India is endowed with a vast solar energy potential. India receives one of the highest global solar radiations – energy of about 5,000 trillion kWh per year is incident over India‘s land mass with most parts receiving 4-7 kWh per m2 per day. The use of solar power will aid in solving the problem of power outage in remote places. Solar energy is a clean, non-polluting, efficient and sustainable energy source which has long term reliability. The efficiency and the reliability of a photovoltaic (PV) plant depend upon efficiency of PV panel, efficiency of inverter and efficiency of Maximum power point transfer (MPPT).Many researchers have developed algorithms to harvest maximum power from the sun. The most popular maximum power point algorithms (MPPTs) are perturb & observation, incremental conductance, fuzzy logic control to name a few. In the present work, perturb & observe MPPT algorithm is chosen to analyze its performance in the photovoltaic applications. The P&O algorithm is implemented in microcontroller and applied to the buck converter. The microcontroller estimates the input power and the converter output power to validate the performance of the p & o algorithm for photovoltaic applications. This paper contains hardware prototype results and respective waveforms using Perturb and Observation MPPT method.
