You have at your desk the issue no. 1/2010 of the journal AUTOMATIKA with which begins my direct responsibility for its future development in the capacity of the Editor-in-chief. I would like to thank the KOREMA presidency for entrusting me with this responsibility. Special thanks to my predecessor Prof. Borivoj Rajković for the enormous effort he invested in regular publishing of the journal a...

The topology and control of three-phase 4-wire DSTATCOM consisting of a operating flexibility in the DSTATCOM consisting of a operating flexibly in the voltage or current control mode. In the voltage control DSTATCOM topology includes three single-phase voltage source converters connected in parallel. The proposed DSTATCOM provides the voltage regulation of power factor correction along with ha...

in this paper, a consistent pattern with the optimal coordinated design of pss and sssc controller to improve the damping of low frequency oscillations is shown. in this design, sensing and signal transmission time delays are considered as effectiveness parameters. the design problem has been considered an optimization problem and biogeography-based optimization (bbo) algorithm is used for sear...

using the facts controllers, such as static synchronous compensator (statcom), as it provides continuous reactive power, in the grid including wind turbine (wt) equipped with doubly fed induction generator, for improving voltage profile (under normal circumstances) and providing a transition ability from inductor generator transition state has been proposed. in this paper, in order to control t...

This paper presents a novel way of generating the reference currents for an active filter and/or a static compensator. A compensator structure is proposed which is capable of balancing an unbalanced delta-connected load that may also draw harmonic currents. In addition to balancing the load, the supply side power factor is also made unity. The theory of instantaneous symmetrical components is u...

This paper presents a novel optimization based methodology to allocate Flexible AC Transmission Systems (FACTS) devices in an attempt to improve the previously mentioned researches in this field. Static voltage stability enhancement, voltage profile improvement, line congestion alleviation, and FACTS devices investment cost reduction, have been considered, simultaneously, as objective funct...

Distribution static compensator is based on power electronic devices technology which utilized to supply rapid changes in active as well reactive of utility grids. This useful achieve corrections factor, balancing load, compensation current and filtering harmonics. Therefore, proposed work investigates the improvement quality by utilizing distribution compensator, equipped battery energy storag...

Given the concern for maintaining voltage stability in power systems integrated with renewable due to a mismatch generation and demand, there remains need invoke flexible alternating current transmission system (FACTS) devices distribution network. The present paper deals identifying locations of placement static var compensator an experimental IEEE 14-bus system; drop different buses is calcul...
