A new computer program is described which permits eigenvalue analysis of the oscillations associated with synchronizing power flow in large electric power systems. The program has been given the acronym AESOPS, for the Analysis of Essentially Spontaneous Oscillations in Power Systems. The program is the principal product of a research project funded by the Electric Power Research Institute. This project was recommended by the Westinghouse Advanced Systems Technology Division and the MAPP/MARCA Dynamic Device Operating Task Force.
