Simulation of Incremental Conductance MPPT Algorithm for PV Systems using LabVIEW

Abstract: Among all types of renewable energies, solar energy has the widespread utilization. This popularity is achieved for its sustainability, cleanliness, ease of maintenance and absolute zero noise characteristics. The global economic convenience of a PV system depends on the cost and the energy conversion efficiency. It is necessary to reduce the cost and increase the efficiency to make solar energy effectively. Thus, MPPT algorithm is necessary in order to track the optimum operating point or maximum power that can be extracted from the PV array. In this paper, Incremental Conductance MPPT algorithm is implemented using LabVIEW (Laboratory Virtual Instrument Engineering Workbench) and its performance is observed.

Keywords: PV system, Incremental conductance, MPPT algorithm, LabVIEW.
