Maximum Power Point Tracking in SPV System under Linear and Non-linear Condition using Dynamic PSO Technique

In this paper, Maximum Power Point Tracking is done in a solar photovoltaic system for maximum harvesting of power from the sun so that the solar power generation can be improved. In this paper a Dynamic PSO a variant of PSO is used for maximum power point tracking in solar PV system under linear and non-linear conditions. A comparative analysis on the performance of Dynamic PSO as well as the conventional techniques such as perturbation and observation and particle swarm optimization technique is done for Maximum power point tracking of Solar Photovoltaic System under linear and non-linear condition. The efficiency of the technique is compared and the best technique is applied for maximum power point tracking in a solar PV system under linear and non-linear conditions that prevails in the atmosphere. Linear and non-linear are conditions, in the atmosphere that occurs due to direct sunlight irradiance and diffused irradiance on the earth’s atmosphere that affects the solar PV panel insolation level. Under varying atmospheric conditions the solar PV generation is made more efficient by using the best Maximum Power Point Tracking technique.
