Abstract

One of the most commonly utilized maximum power point tracking (MPPT) algorithms for photovoltaic (PV) generators is the Incremental Conductance (INC) algorithm. Yet, the operating characteristics of this algorithm at high perturbation frequencies, when the system response to MPPT perturbations is never allowed to settle, have not been addressed in the literature. This paper characterizes system behaviour in this operating mode experimentally for a standalone PV system with a motor-pump load (and a resistive load). Results show that the INC algorithm operating at a high perturbation rate offers higher energy utilization efficiency and better system performance despite the resulting non-periodic waveforms of the system.
