Modeling and simulation of dynamic communication latency and data aggregation for wide area applications
This paper introduces a framework to model two factors: (a) dynamic communication latency and (b) the phasor data concentrator (PDC) for wide area monitoring and control (WAMC) applications. A transport delay model is introduced to simulate continuous variations in latencies and a time synchronization algorithm is represented to mimic the effect of PDCs. The models allow the analysis of latency build up and data aggregation that occurs at the PDC. The proposed models are used to assess the impact of these factors for a WAMC application, namely power oscillation monitoring. Numerical simulations are conducted on the IEEE 39 bus, 10 machine system assummng a PMU at each of the generator buses and across 4 tielines in the system. Modal extraction from the dynamic response using Prony analysis shows that latency has a signrncant impact on the estimates.
