Sensitivity of Modes from Modal Analysis of Electric Grids

A sensitivity analysis is applied to the mode and mode shape calculations of the Matrix Pencil method, in order to measure the robustness of the results. The methodology has been proven to work quickly and accurately when identifying modes, but there has not been testing regarding the ability of the MP method to operate under different time windows and sampling frequencies. A variety of signals are used for testing, including both signals with known and unknown modes in conjunction with the moving time windows and sampling frequencies.
