Abstract
AbstractIn this work, a simulation study and comparative analysis of conventional Maximum Power Point Tracking (MPPT) technique, i.e., Incremental Conductance (IC) with nonlinear technique, i.e., Ripple Correlation Control (RCC), has been done. Photovoltaic (PV) array and the DC/DC boost converter along with MPPT control strategy have been implemented and simulations analysis has been presented for both the techniques for various solar irradiance levels at 25 °C temperature. The system has been designed to achieve 450 V and 10 kW output at 1000 W/m2 irradiation, which is attained through a DC/DC boost converter. Simulation results show that the IC technique’s output is very much affected by oscillations under steady-state and varying environmental conditions, which affects the system’s stability; whereas, RCC removes all ripples from voltage, current, and power outputs in steady-state and upto some extent in transient state, due to its inherent ripple removal feature. However, during transitions RCC also exhibits underdamped response, but it is minimum as compared to other MPPT techniques.KeywordsPhotovoltaic (PV)DC/DC Boost converterMaximum Power Point Tracking (MPPT)IrradianceRipplesIncremental Conductance (IC)Ripple Correlation Control (RCC)
