Measurement-based power system dynamic model for response estimation

Traditional power system dynamic models are very complex due to the intricacy of power system networks and can be inaccurate because of the amount of detail needed and the fact that the grid topology changes every few minutes. However, with the deployment of a large number of phasor measurement units (PMUs), a purely measurement-based model for dynamics estimation and prediction may be obtained. This paper proposes a linear ARX-structured power system dynamic model and presents case studies demonstrating that this proposed model structure is promising in the application of power system dynamic response estimation.
