Use of digital computer simulations to assess long-term power system dynamic response

Abstract
This paper describes the uses of a digital computer program developed to simulate the long-term dynamics of bulk power systems. Power system long-term dynamics, including effects dominant in the period extending for several minutes, often determine whether a power system will successfully avoid cascading failure following a major disturbance. The paper describes the simulation of an evolving disturbance on a hypothetical power system using both a conventional short-term simulation program and a new long-term simulation program. Results for three measures devised to modify the system capability to withstand the disturbance are included.
