摘要

Modern electrical power grids are susceptible to several problems in terms of power quality due to the integration of renewable energy sources, the connection of nonlinear loads, and power electronics-based devices. In this sense, this work proposes a novel nonlinear control scheme that allows, through the use of a power electronic converter, to provide ancillary services to the electrical power grid, intending to achieve three different control objectives: voltage regulation, harmonic distortion compensation, and the power factor correction at a power system node, depending on the end-user requirements, and by doing so enhance the power quality. The proposed control scheme uses nested control loops based on super-twisting sliding modes, nonlinear optimal tracking control, and a fast-convergent harmonic estimator with a decentralized structure. Simulation results validate the effectiveness of our proposed scheme.
