- Abstract:
- The line parameters available to the System Operator can be quite different from actual values because of different reasons, such as aging, manufacturing tolerance, environmental conditions, etc. Proposals have been presented in literature to estimate line parameters and monitor their changes. Synchrophasor measurements from PMUs have appeared as a possible breakthrough for accurate estimation. A novel algorithm has been recently proposed to estimate line parameters in presence of realistic systematic errors in PMU-based measurement chains. This paper aims at characterizing the robustness of the algorithm with respect to possible mismatches of the models associated to PMU measurement errors. Systematic and random contributions are considered at different levels. Simulations on an IEEE test network help in investigating method robustness and possible limits.
