Received Mar 2, 2014 Revised Jul 10, 2014 Accepted Jul 3, 2014 Modern Power Transmission networks are becoming increasingly stressed due to growing demand and restrictions on building new lines. Losing stability is one of the major threat of such a stressed system following a disturbance. Flexible ac transmission system (FACTS) devices are found to be very effective in a transmission network fo...

the share of dc-based renewable energy resources (rers) and electricity storage systems are increasing due to developments of smart grid technologies. moreover, the share of dc-based load has rapid growth due to significant developments of power electronic technologies. therefore, a more flexible power system is required for efficient integration of emerging loads and generators. in this paper,...

This work investigates the effects of the STATCOM (Static Synchronous Compensator), a FACTS (Flexible AC Transmission Systems) device, on small-signal power system angle stability. This investigation is carried out for a single machine connected to an infinite bus via a loss-less transmission line. The study is based on investigation of the eigenvalues of the linearized power system model in th...

There is a great resolution calling for smart grids in recent years. Introduction of new technologies, that make the network flexible and controllable, is a main part of smart grid concept and a key factor to its success. Transmission network as a part of system network has drawn less attention. Transmission switching as a transmission service can release us from load shedding and remove the co...

Flexible ac transmission systems (FACTS) controller can provide better control than conventional control and achieve fast control response time. Static synchronous compensator (STATCOM) is one of the key FACTS devices based on voltage source converter (VSC) technology whose capacitive or inductive output current can be controlled independent of the ac system voltage. In this review paper, the a...
