Prony analysis has been used to estimate oscillation modes from ringdown responses in a power grid. When applying Prony analysis, several factors must be considered to estimate the modes accurately. In this paper, a general prediction model is proposed for the Prony analysis. The influence of decimation factors, model orders, and linear solvers on estimation accuracy is studied using the Monte Carlo method with a goal of providing a reference for applying Prony analysis to estimate electromechanical modes.
