A detailed model of WAMS delays including pseudo-periodic, stochastic and constant components is presented. Then, the paper discusses numerical methods to evaluate the small-signal stability as well as the timedomain simulation of power systems with inclusion of such delays. The small-signal stability analysis is shown to be able to capture the dominant modes through the combination of a characteristic matrix approximation and a Newton correction technique. A case study based on the IEEE 14-bus system compares the accuracy of the small-signal stability analysis with Monte-Carlo time-domain simulations. Finally, the numerical efficiency of the proposed technique is tested through a real-world dynamic model of the all-island Irish system.||Funding Details:||Science Foundation Ireland||Type of material:||Journal Article||Publisher:||IEEE||Journal:||IEEE Transactions on Power Systems||Copyright (published version):||2018 IEEE||Keywords:||Time-varying delay; Delay differential algebraic equations (DDAEs); Small-signal stability; Wide-area measurement system (WAMS)||DOI:||10.1109/TPWRS.2018.2865559||Language:||en||Status of Item:||Peer reviewed|
