“…As a result, data takes longer to transmit, which may cause unacceptable delays in time-critical protection data transmissions, such as those dealing with wide-area power system stability discussed in [15]. Therefore in order to improve the efficiency of the OAC security layer, the symmetric mode does not include the frame authentication with its data transmissions.…”

The OAC security is designed as an extension for a Canadian utility integrated P&C system innovation. The OAC security increases interactions with DNP3 data-link layer to enhance utility network security that is especially important for time-data-critical transmissions of protection information. The OAC security does not alter existing DNP3 specification to maintain interoperability for devices not using OAC. The OAC security uses two independent encryptions, one for exchanging security keys and one for transmitting data, to minimize time required for security operations. The OAC security relaxes authentication requirements to reduce transmission overheads and increase efficiency.

“…Although monitoring applications are now found in several utilities, control applications for improving angular and voltage stability are still scarce and a challenging issue [12]. However, several works on the use of phasor measurement for power system control have presented theoretical foundations for a more disseminated use of this new technology for control applications, as for instance, references [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24]. This paper presents a design method for a hierarchical twolevel control scheme aiming at the enhancement of power system small-signal stability, using a multivariable system approach.…”

In this paper the design of power system stabilizers for small-signal stability using phasor measurements is considered. An approach based on optimal control with structural constraints is proposed to design a two-level hierarchical control to improve the power system performance. The control scheme is discussed and eigenanalysis and time-domain simulations for a Brazilian equivalent test system are performed to assess the performance of the design. The effect of time delays, the robustness to loss of communication links and to topological changes are included in this analysis.

“…Inclusion of these SPM units as additional and remote inputs in feedback control loops, for PSS and FACTS devices, allows a coherent picture of the entire network in real time [13]. A wide-area signals based hierarchical control has been successfully utilized in [14] to enhance power system stability and security. In [15] it has been reported that a combination of both SPM and FACTS technologies can result in very powerful potential for real time sensing, monitoring and counteracting the effects of large disturbances in power system.…”

This paper proposes a Linear Matrix Inequality (LMI) based ∞ Η robust controller design method for enhancement of damping of inter-area oscillations in a multimachine power system network. A Four-input, Single-output (FISO) ∞ Η controller is designed for a Thyristor Controlled Series compensator (TCSC) employing Wide Area Measurement (WAM) based stabilizing signals as generator speed. The major concern of signal transmission delay in wide area measurement is overcome here using the novel concept of Synchronized Speed Phasor Measurement (SSPM) with Global Position Satellite System (GPS) technology. The controller design has been carried out based on the ∞ Η mixed-sensitivity formulation in a LMI framework with pole-placement constraint. The small signal stability performance of the controller has been examined employing eigenvalue as well as time domain analysis for different operating scenarios of a 14-area real power system comprising of 24 numbers of generators, 203 buses and 266 lines. The designed controller has been found to be robust against varying generation and load power demand as well as for transmission line outage.
