“…The PID and the cascade controllers exhibit accurate performance; however, when there was no load connected downstream the DVR, only the SF controller was able to properly damp the LC filter resonance. Control alternatives like hysteresis controllers can be found in the literature [23,24], and a comparative analysis with this alternative is of interest for further research. All the control system developments were validated in a 5 kVA prototype of a DVR, with accurate results.…”

“…However, a Posicast controller leads to poor results when the system dynamics are not accurately known. Alternatively, Petkova et al [23] and Antchev et al [24] presented a fast sliding-mode controller for a series active power filter (SAPF) that protected a load against voltage harmonics. The main advantage of this controller was robustness against variations in the system parameters, and this feature is of interest for its application to a DVR.…”

Voltage sags result in unwanted operation stops and large economical losses in industrial applications. A dynamic voltage restorer (DVR) is a power-electronics-based device conceived to protect high-power installations against these events. However, the design of a DVR control system is not straightforward and it has some peculiarities. First of all, a DVR includes a resonant (LC) connection filter with a lightly damped resonance. Secondly, the control system of a DVR should work properly regardless of the type of load, which can be linear or non-linear, to be protected. In this paper, a digital state-feedback (SF) controller for a DVR is proposed to address these issues. The design and features of the SF controller are studied in detail. Two pole-placement alternatives are discussed and the system robustness is tested under variations in the system parameters. Furthermore, implementation aspects such as discretization not commonly addressed in the literature are described. The controller is implemented in its incremental form. A decoupling system for the dq-axis dynamics that takes into account system delays and the load current is proposed and analytically studied. The proposed controller is compared with two other alternatives found in the literature: a Proportional-Integral-Differential (PID) controller and a cascade controller. The effect of the load connected downstream a DVR is also studied, revealing the potential of the SF controller to damp the resonance under light load conditions. All control system developments were tested in a 5 kVA prototype of a DVR connected to a configurable grid.

“…Usually pulse-width modulation is used to control the filters, but also researches of sliding mode control of the filters on several variables are known (Cardenas et al, 1999;Hernandez et al, 1998). In this sub-chart sliding mode control of a single-phase series active power filter on one variable -the supply voltage of the load is studied (Antchev et al, 2007;Antchev et al, 2008). …”

“…In such a way, the system of APF's does not consume any active power from the AC grid, its supply being provided by the renewable energy source. a) Series APF Its control system is synchronized with the voltage of the public distribution grid; it tracks continuously the instantaneous values of the local-grid voltage U L , and compares them to those of a reference sinusoid of fixed value [6]. Switching over the filter devices is performed in such a way that at any time the voltage U F complements the instantaneous values of the voltage U S from the public distribution grid to those of the reference sinusoidal voltage.…”

The share of distributed generation (DG) within the distribution network increases strongly. A lot of these DG units are driven by Renewable Energy Sources (RES). Up to now, these units only inject active power depending from the availability of their primary source. In future on the one hand DG units have to contribute to grid stability, but on the other hand DG units can provide additional functionalities in order to offer a surplus value for the customer. Therefore especially inverter-coupled systems are well suited. Additional functionality could be improvement of Power Quality and Reliability (PQR), but also peak shaving, provision of control energy or reactive power compensation is conceivable. This paper presents several approaches of such multifunctional inverter systems developed by ISET e.V., SMA and TU Sofia with the focus on PQR.
