Synchronized Wide-Area Monitoring Systems (WAMS) involve the use of power system-wide measurements to avoid large disturbances and reduce the probability of catastrophic events. In these systems a large volume of raw data is collected by distributed sensors and sent to central servers for post processing activities.Many research works conjectured that this hierarchical monitoring paradigm could be not affordable in addressing the increasing network complexity and the massive data exchanging characterizing modern smart grids. Unaffordable complexity, hardware redundancy, network bandwidth and data storage resources are the main barriers imposed by technology and costs.Moreover, in WAMS the global absolute time reference for sensors synchronization is typically obtained by satellite-based timing signals processing. Since these signals are extremely vulnerable to radiofrequency interference (i.e. cyber-attacks), effective countermeasures aimed at increasing the resilience of synchronized WAMS to external and internal interferences need to be designed.In trying and addressing these challenges, in this paper the role of decentralized consensus protocols for decentralized and synchronized wide area smart grids monitoring is analyzed.

“…The resulting parameter settings are T ωg = 30 ms; τ = 30 ms; T w = 5 ms (29) where the time constant of the frequency measurement setting T ωg is based on [22], and the transmission delay setting τ is from [23]. The action of the proposed controller was limited to the first two cycles to avoid an increasingly detrimental effect of the delays of Figure 8 in subsequent cycles.…”

Abstract:Power system transient stability is a challenge when integrating large-scale wind turbines into weak grids. This paper addresses the issue of transient stability in such situations by optimizing a wind turbine's active current behavior. A wind turbine's active current reference controller and its setting optimization method are proposed based on analyses of two associated problems: the mechanism for improving transient stability of a single (synchronous) machine infinite bus (SMIB) system, as well as the various physical factor dependencies dictating how active and reactive wind turbine currents affect the swing dynamics of synchronous machines. Analysis of the first problem guided the design of the controller's main structure. Analysis of the second problem guided selection of the control object within a wind turbine's active and reactive currents, as well as helped recognition of the influential physical factors that must be considered in the parameter setting process. The efficiency of the controller and the validity of the analyses were verified by case studies using Kundur's two-area system.
