“…Another important component of latencies is the signal flying time to travel through the medium and routers at each link. Their stochastic behaviour contributes to the total time delay [35].…”

“…Firstly, τ v denotes the total time delay produced by the devices mentioned in the previous section (PMU, PDC, SPDC). Secondly, τ link is the total additional latency due to the links of the communication process; τ link is related to the weather conditions and the medium and is generally greater than τ v [35]. The sum of these values is given by:…”

Time-delay is inherent to communications schemes in power systems, and in a closed loop strategy the presence of latencies increases inter-area oscillations and security problems in tie-lines. Recently, Wide Area Measurement Systems (WAMS) have been introduced to improve observability and overcome slow-rate communications from traditional Supervisory Control and Data Acquisition (SCADA). However, there is a need for tackling time-delays in control strategies based in WAMS. For this purpose, this paper proposes an Enhanced Time Delay Compensator (ETDC) approach which manages varying time delays introducing the perspective of network latency instead dead time; also, ETDC takes advantage of real signals and measurements transmission procedure in WAMS building a closed-loop memory control for power systems. The strength of the proposal was tested satisfactorily in a widely studied benchmark model in which inter-area oscillations were excited properly.

“…In simple terms it requires collating information on the description of the current state of the power grid over a large geographical. Then, this information can be analyzed, for instance to diagnose current situation or predict the evolution of the power grid state under different operational conditions and energy control strategies [60]- [62]. This application requires very high frequency or granularity of information in order of milliseconds collected from the transmission networks and electric substations about the state of the power grid [10], [15].…”

“…One of the most important applications that smart grids should support is real-time wide-area situational awareness (WASA), which is defined as the ability to build a high-resolution description of the current state of the power grid over a wide area. Then, this information can be analyzed, for instance to predict the evolution of the power grid state under different operational conditions and energy control strategies [26,[70][71][72].…”
