Adaptive Nonlinear Control Scheme for Three-Phase Grid-Connected PV Central Inverters

Abstract

Owing to cost-effectiveness of feeding generated photovoltaic (PV) energy directly into the utility grid, and since grid-connected photovoltaic (GPV) systems have a nonlinear time-varying nature, this paper presents a new control approach for three-phase single-stage GPV systems under uncertainties, using a Lyapunov-based control scheme. The proposed scheme… (More)
