An Unified Power Flow Controller (UPFC) is a typical Flexible AC Transmission System (FACTS) device playing a vital role as a stability aid for large transient disturbances in an interconnected power system.This paper deals with the design of Feedback Linearising Controller (FBLC) for UPFC.The disturbances are created in the SMIB system and the results are simulated.The results proved the supre...

Owing to the technological advancement in communication areas, presently, the security and the reliability of operating power system is very much possible on real-time platform. Phasor measurement units (PMUs) are based on these advance communication technology and are one of the most important equipment for electric utility, now a days, helpful in maintaining a healthy operating power system. ...

Preventing denial-of-service attacks in wireless sensor networks is difficult primarily because of the limited resources available to network nodes and the ease with which attacks are perpetrated. Rather than jeopardize design requirements which call for simple, inexpensive, mass-producible devices, we propose a coping strategy that detects and maps jammed regions. We describe a mapping protoco...

The exact ground-state Kohn-Sham (KS) potential for the helium atom is known from accurate wave function calculations of the ground-state density. The threshold for photoabsorption from this potential matches the physical system exactly. By carefully studying its absorption spectrum, we show the answer to the title question is no. To address this problem in detail, we generate a highly accurate...
