Modern approach for hybridization of PSO-INC MPPT methods for efficient solar power tracking

Abstract

Solar power became an increasingly popular as a source of renewable energy since past decade. The maximum power point tracking (MPPT) is easy and efficient algorithm used for Power tracking during the abundant availability of sunlight and at high temperature. However this might not be the case during weather intermittency. Sudden change in weather conditions cause sudden change in irradiance and gradual change in temperature can impact on the Power tracking capability of converter because of some constraints in the MPPT algorithm used. Study shows that during such variable weather conditions if large disturbance occurs in the power system, PV plants without LVRT capability may probably trip themselves from the grid. As the solar PV system has non-linear characteristics because of weather variations, it is important to use appropriate MPPT technique which can effectively track MPPT at sudden variation to improve overall efficiency of the PV panel. Here in the paper we proposed and analysed one of the new hybrid MPPT method which is - PSO-INC hybridised MPPT Method on solar panel of 300W. Through this we will see the steps that involved during the development of this new MPPT algorithm its simulation results
