A comparitive and analytical study of various incremental algorithms applied in solar cell

With the growing demand for energy we changeover to renewable energy from non-renewable energy. Solar energy with its abundant infusion in to earth´s atmosphere, it makes lot of sense to utilize the potential of sun and use it for growing requirements. First promising candidature for the large scale spreading of renewable energy source is the photovoltaic technology. The amount of power generated from a photovoltaic (PV) system mainly depends on the following factors, such as temperatures and solar irradiances. According to the high cost and low efficiency of a PV system, it should be operated at the maximum power point (MPP) which changes with solar irradiances or load variations. This paper is aimed to study the behavior of different incremental algorithm in Maximum Power Point Tracking (MPPT) techniques applied to solar modules. Technique such as fixed-step Incremental conductance, variable-step incremental Conductance and Variable Step size incremental Resistance are considered in this work and analyzed. In this paper, a comparative study will be made on the above technique considering criteria such as simplicity of implementation and capability to follow irradiance variations. All the simulation work were performed on MATLAB platform.
