“…Subsequently, for each subsystem, using a control Lyapunov function that employs the states of the system as virtual inputs for the subsystems, it is possible to obtain the original control law for global stability and regulation. Recently, the backstepping technique has been applied also in the contest of SG control and stability to cope with non-linearity and uncertainties in the SG model [51][52][53]. However, when the order of the system increases, the number of states grows as well.…”

This paper discusses the application of robust control techniques to a smart grid (SG) in order to find more powerful and suitable control tools to guarantee SG robustness. Two key aspects are in particular discussed. The first one relates to the need of a suitably model for the SG. The second one relates to the selection of an appropriate robust control technique to guarantee rejection of the adverse effects caused by mutual interactions among control loops and model uncertainty. The final purpose is to bridge the gap between the power of robust control theorems and the reality of SG operations.

“…Since the fundamental PR controller acts on a very narrow band around its resonant frequency ω, the implementation of harmonic compensator for low-order harmonics is possible without affecting the PR controller behavior and dynamics [51,52]. In addition, single frequency compensation, selective harmonic compensation is proposed by cascading several resonant blocks tuned to resonate at the desired low-order harmonic frequencies to be compensated.…”

In this paper, a single-phase single-stage photovoltaic (PV) grid-tied system is investigated. The conventional pulse width modulated (PWM) voltage source inverter (VSI) is replaced by a PWM current source inverter (CSI) for its voltage boosting capabilities, inherent short-circuit proof and higher reliability features. Modeling, design, and analysis of the considered CSI are presented altogether with enhanced proposed control loops aided with a modified PWM technique. DC-link even current harmonics are commonly reflected as low-order odd harmonics in the grid resulting in a poor quality grid current. In order to overcome the latter, a high performance proportional resonant controller, applied in the inverter inner grid current loop, is proposed using cascaded resonant control units tuned at low-order frequencies to eliminate injected grid current harmonics. Hence, with a less-bulky smoothing inductor at the CSI DC-side, grid power quality and system efficiency are simultaneously improved. Simulation and experimental results verify the proposed controller effectiveness.
