Novel Incremental Conductive Perturbation Algorithm for Improved Output of MPPT

Abstract

Solar energy is observed as a potential source of electric power generation. Tracking the point at which the power is maximum (MPPT) is required for any Photovoltaic systems to utilize the PV module in an optimized way. This research was focused to scrutinize the capacity of the technique which utilizes Perturb and Observe (P&O) and Incremental Conductance (IC) method together to track the point at which the power is maximum. Thus this proposed algorithm is named as Novel Incremental Conductive Perturbation Algorithm (NIPCA). In this paper, proposed MPPT is controlled based on the derivation which utilizes improved relations. The proposed technique recognizes the steady state and halts the artificial perturbations. Thus oscillations around MPPT are eliminated and steady power output from the PV panel at the MPP value is obtained. Proposed structure is simulated in SIMULINK environment in MATLAB. Comparison is done with the existing algorithms by utilizing the simulation results.
