FACTS technology improves the power system stability by providing the necessary compensation to transmission lines. Interline Power Flow Controller (IPFC) is one such unique concept for exchange of power flow in case of interconnected systems. In this paper, an IPFC is proposed to improve the voltage stability of a given power system network consisting of three transmission lines. The gate trig...

Wind power technology has been developing widely in recent years. Several research fields in power systems such as prediction of wind speed, wind generator system modeling, system stability and control of wind energy conversion system are emphasized further with the consideration of wind power. With increasing penetration level in power system, the issue concerning the influence of wind power o...

This paper presents review of various techniques used for enhancement of power system stability. Various FACTS devices including UPFC, TCSC, SSSC, TCBR, FCL which are used for enhancing transient stability in power system are reviewed in this paper. Survey up to 2013 is done and the information collected in this paper is sufficient for finding out relevant references in the field of power syste...

In recent years, power demand has increased substantially while the expansion of power generation and transmission has been severely limited due to limited resources and environmental restrictions. As a consequence, some transmission lines are heavily loaded and the system stability becomes a power transfer-limiting factor. Flexible AC transmission systems (FACTS) controllers have been mainly u...

Smart grid is a new developing concept in power system. This technology observes the state of power system and intelligently take decisions to quickly clear faults, restores power and monitor demand to preserve the stability and performance of the electric power network formerly done by engineers. This paper discusses the technologies of smart grid and presents a developed model to illustrate t...

This paper presents the concept of simultaneous ac-dc power transmission. Long extra high voltage (EHV) ac lines cannot be loaded to their thermal limits due to this instability occurs in the power system. It is difficult to load long extra high voltage (EHV) ac lines to their thermal limits as a sufficient margin is kept against transient instability. With the model proposed in this thesis, it...

In this paper the effect of presence of wind farms on relay coordination at fault condition and transient response at reclosing condition is studied. Wind farms as one of the important distribution generations (DGs) are so effective on overcurrent relay coordination in power systems. As well as Wind farms cause to severe oscillations on voltage, power and frequency in power system after reclosi...
