The paper presents new approaches and principles for identifying the conditions of stability disturbance based on detecting dangerous disturbances in early stages using information about changes regime parameters their Rate Change. As a mode parameter, mutual voltage angle between controlled 500 kV substation its Change was selected study. It is suggested to take values mentioned from Wide Area...

Electric power system is a critical infrastructure and loss of its resilience and/or operability can lead to negative consequences for the national economy. Modern power systems based on sophisticated computer and communication technologies are characterized by elevated vulnerability to different types of unauthorized malicious access, i.e. cyber-attacks. Wide area measurement system which is b...

Advances in mobile technology have led to the emergence of the "smartphone", a new class of device with more advanced connectivity features that have quickly made it a constant presence in our lives. Smartphones are equipped with comparatively advanced computing capabilities, a global positioning system (GPS) receivers, and sensing capabilities (i.e., an inertial measurement unit (IMU) and more...

Multicast is proposed as a preferred communication mechanism for many power grid applications. One of the biggest challenges for multicast in smart grid is ensuring source authentication without violating the stringent time requirement. The research community and standardization bodies have proposed several authentication mechanisms for smart grid multicast applications. In this paper, we evalu...

It is expected that a coordinated operation of several system integrity protection schemes will become necessity in the future. This research represents an innovative strategy for coordinating under-frequency load shedding and intentional controlled islanding improving electric power stability resilience. In great majority real-world cases, both approaches follow conventional tactics, i.e., dis...

Nowadays, different power systems are connected to each other due technical and economic reasons form a complex developed network. Such networks measure send system data decision-making centers for control protection. This information transmission is accompanied by delay causes the performance of system’s damping controllers be affected. To improve dynamic stability, supplementary controller in...

The deployment of a synchrophasor-based widearea measurement system (WAMS) in a power grid largely improves the observability of power system dynamics and the operator’s real-time situational awareness for potential stability issues. The WAMS in many power grids has successfully captured system oscillation events, e.g. poorly damped natural oscillations and forced oscillations, from time to tim...

This paper presents critical survey along with the novel concept of smart power flow controller with Phasor Measurement Units (PMUs) signals for stability enhancement of a large power system. Also, the current status of Wide Area Measurement Systems (WAMS) and developments in real time applications of synchrophasor technology in power system has been adequately addressed. It has been noticed th...

1 Abstract-This paper proposed the design of wide-area robust damping (WARD) controller for multiple Flexible AC Transmission Systems (FACTS) devices to enhance the stability of power system with considering time delay of wide-area signals. Firstly, as power systems interconnect more and more to exchange large amounts, wide-area measurement system (WAMS) is widely applied to monitor and control...
