Modeling and simulation of Incremental conductance Maximum Power Point tracking

Abstract

To utilize the maximum amount of solar energy application of maximum power point tracking must be employed in PV systems. The trait of a solar cell is non-linear in nature. The intensity of the solar radiation falling on the earth surface relies on various parameters like clouds, water vapor, pollution, absorption, scattering and in climatic factors. A PV system without MPPT hardly produces maximum power, which also changes the Maximum Power Point of PV system with respect to a particular environmental condition which ultimately leads to low power. In order to track PV system's MPP Incremental conductance (IC) algorithm provides higher steady-state accuracy with better and efficient output compared to the non MPPT system. Various results of simulation are conferred here.
