Implementation of MPPT Algorithm using Firefly Technique for Solar Photovoltaic Systems

This paper presents a new firefly technique based Maximum Power Point Tracking (MPPT) algorithm for solar panel. The Solar panel can produce maximum power at a particular operating point called Maximum Power Point (MPP).To produce maximum power and to get maximum efficiency, the entire photovoltaic panel must operate at this particular point. Maximum power point of PV panel keeps on changing with changing environmental conditions such as solar irradiance and cell temperature. Thus to extract maximum available power from a PV module, MPPT algorithms are implemented. The solar panel is modelled and analysed in MATLAB/SIMULINK. In this paper, Incremental Conductance approach & firefly algorithms based MPPT has been developed and comparative studies between them shows more sophisticated approach of obtaining maximum power is also being analysed. Simulation results also shows the effectiveness of the firefly based technique to produce a more stable power.
