A Flicker Compensation Strategy
IEEE Transactions on Power Electronics, 2009Co-Authors: G. Buja, S. CastellanAbstract:This letter is concerned with the strategy adopted by an active compensator to mitigate the flicker phenomenon in a Power system. After illustrating two conventional strategies, a novel strategy that forces the compensator to deliver a particular value of the Instantaneous Imaginary Power absorbed by the time-variant load is proposed. The strategy is compared with the two conventional ones in terms of magnitude of the voltage fluctuations at the point of common coupling (PCC) and size of the capacitor in the dc bus of the active compensator. Suitable equations and vector diagrams are derived. They show that the novel strategy outweighs the other two by eliminating most of the PCC voltage fluctuations without the need for a large capacitor. The theoretical findings are substantiated by simulation results.

Compensation strategy for an active flicker compensator
2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 1Co-Authors: G. Buja, S. CastellanAbstract:The paper is concerned with the development of an active flicker compensator. It is shown that the compensation of the fluctuating component of the Instantaneous Imaginary Power produces a substantial, but not complete, elimination of the voltage fluctuations. A novel compensation strategy is presented, which reduces the voltage fluctuations drastically while keeping unchanged the voltage ripple on the dc bus of the converter. The effectiveness of the compensation strategy is demonstrated by simulation. The laboratory setup designed for experimental purposes is under development and is described in the paper.

On the detection of load active currents for active filter control
IEEE Transactions on Power Electronics, 1996Co-Authors: E. Destobbeleer, L. ProtinAbstract:The control of current source converters used as active filters can be based on either the current active components detection or the Instantaneous Imaginary Power detection from which all or only a part can be used. The authors study the conditions in which this second method is equivalent to the first one and propose an improvement for the cases when it is not so.

Instantaneous Power compensation in three phase systems by using p q r theory
IEEE Transactions on Power Electronics, 2002Co-Authors: Hyosung Kim, Frede Blaabjerg, Birgitte Bak-jensen, Jaeho ChoiAbstract:This paper proposes a novel Power compensation algorithm in three-phase four-wire systems by using p-q-r theory. The p-q-r theory is compared with two previous Instantaneous Power theories, p-q theory and cross vector theory. The p-q-r theory provides two-degrees of freedom to control the system currents by only compensating the Instantaneous Imaginary Power without using any energy storage element. The definition of Powers maintains Power conservation, and agrees well with the general understanding of Power. Simulation results show the superiority of p-q-r theory both in definition and compensation.
