Modal parameter estimation using synchrophasors

The development and diversification of the Uruguayan power electric infrastructure, with the significant incorporation of renewable sources is leading to changes in the operation criteria. With all these efforts to make the power system more efficient and smarter, real-time analysis are becoming more required and necessary. This paper investigates a method of estimating the electromechanical modes from multiple synchrophasors. The application includes a method with the objective to provide the maximum observability information of the electromechanical modes of interest. The study specifically analyzes the performance of the method in the 10 machine 39 bus IEEE test system and in the Uruguayan power system.
