“…The extension of this scheme described in [10] include measurements taken at remote buses to assist the estimation of the Thévenin equivalent. To avoid the time delay of leastsquare estimation, it is proposed in [11] to obtain the Thévenin equivalent from measurements taken at a single time but at both ends of a transmission corridor. A two-bus equivalent is also used in [13] where the large network behind a load bus is represented by a source in series with a transmission line (using time synchronized PMUs), preserving power flow and voltage information at the bus of concern.…”

Abstract-This paper deals with long-term voltage instability triggered by the outage of transmission or generation equipments. It is shown how the onset of voltage instability could be detected in real-time from post-disturbance bus voltages provided by Phasor Measurement Units (PMUs), assuming observability of the whole region prone to voltage instability. An extended set of equilibrium equations is fitted to the measurements and the change in sign of sensitivities is monitored. The latter are easily computed even for a large system. The important effects of overexcitation limiters and load tap changers are taken into account. The approach is illustrated on a 52-bus 20-machine system, where PMU outputs are simulated from detailed time simulation.

“…Serviceoriented concept moves centralized EMS application to small size distributed control center [7,8,14]. Control and protection functionality can be located at any place where wide area measurements are able to merge into the system [15,16] . From what has been discussed above, information technology (IT) is a primary requirement for modern power system.…”

This position paper presents initial research and investigation on a unified framework combining two independent systems, the legacy SCADA system and the synchronized phasor data system, that share the same measurement sources, i.e., current and voltage transducers and the same communication medium. In this framework, conventional SCADA system coupled with substation automation system are modeled together with synchronized phasor systems. The contribution of this paper also includes a state-ofthe-art survey of topics related to the proposed architectures. Furthermore, an overview of the data flows between substation and control centers including both SCADA and phasor measurements are presented. Taking into consideration the growing interest in communication and automation standardization this paper also addresses the communication between the substations coupled with relevant standards and technology.
