Lately, new solutions have been added to the control of autonomous grids, which improve the way the power grids operate. These changes may affect the reliability and safety of power distribution grids, the dynamic stability being a real concern. This issue is more prominent in autonomous microgrids (MGs) with high penetration of renewable energy sources. On this topic, this paper aims to study how...
Taking the unified power flow controller as an example, this paper states the applying foreground of flexibility AC transmission system technology in distribution systems, which comprise wind power generators. As for the impacts of the wind power on the power systems, this paper indicates the deficits of the unified power flow controller, proposes the idea that integrating the energy storage system...
The integration of large-scale distributed generation (DG) and energy storage significantly affect the dynamic behaviors of distribution systems. Distributed systems are facing new challenges in terms of their dynamic behaviors due to the addition of large-scale DG into low-voltage distribution systems. This paper analyses the important effects of the penetration of large-scale wind, solar and energy...
This paper presents a robust control scheme for a static synchronous compensator (STATCOM) coupled with a battery energy storage system (BESS) for improving the dynamic oscillations damping and the transmission power quality in electric power systems. The presented STATCOM/BESS controls both reactive and active power injection/absorption to/from the power system. It is investigated the performance...
In order to study the applications of ESS in power systems, this paper proposes a standard procedure to develop a full mathematical dynamic model of power systems installed with ESS, which include SMES, AC, BESS and FESS. Results of computer simulation are presented to demonstrate the effect of ESS on power system dynamics. Investigation of power system stability as affected by the installation of...
