“…Different control strategies have been recently reported in [9][10][11][12] for this particular HPF topology. In [9] the authors present a controller comprising stages, namely, a current harmonics compensation stage and a regulation stage.…”

“…This solution proposes the insertion, in the HPF topology, of an extra resistor for damping purposes, which leads to unnecessary power losses. In [11] a bidirectional control principle is proposed to solve the problem of harmonic over-current in the HPF. The authors achieve grid-side current harmonics reduction with immunity to passive filter parameters deviation.…”

“…The proposed model-based controller comprises proper damping terms to guarantee stability; an explicit mechanism composed by a bank of resonant regulators to achieve harmonics compensation [13]; and an adaptive algorithm to cope with parametric uncertainties. The damping terms in the proposed scheme avoid the unnecessary power losses of the control algorithm proposed in [10], while the adaptive algorithm avoids the unnecessary use of extra voltage sensors of the controller proposed in [11]. Positive and negative sequences are explicitly considered along the modelling and controller design to guarantee a proper operation under unbalanced conditions.…”

“…Positive and negative sequences are explicitly considered along the modelling and controller design to guarantee a proper operation under unbalanced conditions. Hence, the novelty of this paper, as compared to previous works [9][10][11], is the proposal of a model-based controller to compensate current harmonic distortion at the point of common coupling (PCC) in the general case of distorted and unbalanced load current, under a distorted and unbalanced source voltage operation. That is, our proposal considers simultaneous conditions of distortion in both voltage and current that have not been reported so far.…”

This study presents a model-based controller for a hybrid power filter (HPF) to reduce the current harmonic distortion in a three-phase system for a general operation case considering unbalanced and distorted source voltages and load currents. The HPF comprises an active power filter (APF) grid connected by means of an LC passive filter. This topology is aimed to reduce the current rating handled by the APF, representing a cost effective solution. The controller design is split into two stages, a first one to control the fundamental component of the system dynamics, and to regulate the DC voltage; and a second stage to compensate the harmonic distortion caused by a non-linear load. For this, the harmonic compensation scheme forces the injection of the required harmonic current to the point of common coupling. The proposed scheme keeps the very familiar proportional-resonant control structure. The compensation of the load reactive current is left to the passive filter. Experimental and simulation results are presented to exhibit the benefits of the proposed control solution.

“…Among the various viable hybrid active filter topologies, parallel hybrid active filters present a cost-effective solution for harmonic filtering and reactive power compensation of high power nonlinear industrial loads, due to the small rating of the active filter (2%-3%) of the load KVA rating [6]. Thus, they have attracted increasing attention [7][8][9][10][11].…”

Abstract:The traditional repetitive controller has relatively worse stability and poor transient performance because it generates infinite gain at all the integer multiples of the fundamental frequency, and its control action is postponed by one fundamental period (T 0 ). To improve these disadvantages, many repetitive controllers with reduced delay time have been proposed, which can selectively compensate the odd harmonics or 6k ± 1 harmonics with delay time reduced to T 0 /2 and T 0 /3, respectively. To further study in this area, this paper proposes an improved repetitive scheme implemented in a stationary reference frame, which only compensates the 6k + 1 harmonics (e.g., −5, +7, −11, +13) in three-phase systems and reduces the time delay to T 0 /6. Thus compared with the earlier reduced delay time repetitive controllers, the robustness and transient performance is further improved, the waste of control effort is reduced, and the possibility of amplifying and even injecting any harmonic noises into the system is avoided to a great extent. Moreover, the proposed repetitive scheme is used in the control of a three-phase hybrid active power filter. The experimental results validate the effectiveness of the proposed repetitive control scheme.
