چکیده

SUMMARY Dynamic phasor modeling technique is mostly applied on power electronics devices. In this paper, application of the dynamic phasor modeling technique is extended to other major power system components. Starting from the detailed time-domain models, the dynamic phasor models for these components are derived and implemented. Further, an efficiency and accuracy comparison of the dynamic phasor modeling technique with other conventional modeling techniques-like the standard models in three-phase ABC reference frame (e.g. in EMTP) and models in DQ0 reference frame (e.g. in SIMPOW)-is given. A systematic comparison is warranted by simulating these differently modeled components in a Matlab based common simulation framework. Furthermore reduced order dynamic phasor models of the components are derived and results are compared with other production-grade transient stability programs. Simulation results for two test cases are shown.

Comparative Studies of Clustering Techniques for Real-Time Dynamic Model Reduction

Dynamic model reduction in power systems is necessary for improving computational efficiency. Traditional model reduction using linearized models or offline analysis would not be adequate to capture power system dynamic behaviors, especially the new mix of intermittent generation and intelligent consumption makes the power system more dynamic and non-linear. Realtime dynamic model reduction eme...
