“…The shunt active power filter (SAPF) is used for power factor correction, for current harmonics elimination and, in case of three-phase systems, for current unbalances compensation [1][2] [3]. In addition, as presented in [4] and [5], to mitigate the power quality (PQ) problems, the SAPF can also be used for interfacing renewable energy sources with the power grid (PG). Moreover, as presented in [6], in [7] and in [8], the functionalities of SAPF can be incorporated in electric vehicle battery chargers, representing a relevant contribution for the future smart grids, where the electric vehicle can be seen as a dynamic controllable load in the PG.…”

Nowadays, the majority of electronic equipment behave as nonlinear loads, introducing Power Quality (PQ) problems into the Power Grid (PG), namely, current harmonics and low power factor. These PQ problems contribute to the reduction of the efficiency of the transmission and distribution PG, as well as induce the malfunctioning of sensitive loads connected to the PG. Therefore, the development of equipment able to mitigate these PQ problems is extremely important. In this context, this paper presents a novel single-phase Shunt Active Power Filter (SAPF) based on a current-source converter, where the key differencing factor, when compared with the conventional approach, is the reduced dc-link. As the proposed topology requires a reduced dc-link, it represents a relevant advantage, since a typical current-source converter needs an inductor with a high inductance in dc-link, which results in higher losses, costs and component sizing. The proposed SAPF with reduced dc-link is introduced in detail along the paper and a comprehensive comparison with the conventional SAPF is established based on computer simulations. Besides, an experimental validation was carried-out with a developed laboratory prototype, validating the main advantages of the proposed SAPF with reduced dc-link.

“…With this functionality for the LSS, besides exchanging active power with the grid, the aLSS also allows to reduce the PQ degradation (as harmonic distortion of the current, current imbalance, and low power factor) [12][13] [14]. In this way, the ac-dc converter of the LSS operates with the key characteristics of a SAPF [15][16][17] [18]. It is important to note that the PQ problems must be solved, since, in the long term, they can cause malfunctions in sensitive equipment, causing a reduction in their life time and high monetary costs to the consumer.…”

This paper presents a load-shift system with advanced functionalities to interface the power grid (PG). When compared with the conventional approach, an advanced load-shift system (aLSS) permits the compensation of power quality (PQ) problems for the grid-side, namely problems related to current harmonics, current imbalance, and power factor. The proposed aLSS is composed by a bidirectional ac-dc converter to interface the PG and by a bidirectional dc-dc converter to interface an energy storage system (ESS). Since the main innovation is related with the PG interface, the focus of this work is on the analysis of the ac-dc converter, which is based on a three-phase four-leg converter. A theoretical study and the details concerning the control algorithm are presented and discussed along the paper. A laboratory prototype of the proposed aLSS was developed and the details of implementation are described in the paper. Experimental results obtained with the developed prototype prove that the aLSS contributes for the technology progress in this area, validating a new concept of operation concerning the PQ on the PG side.
