Abstract

The effects that are modeled in recently developed midterm stability programs are described. A tool that can screen large numbers of contingencies and operative condition changes to determine which need more careful study by full midterm stability simulation has been developed. The screening tool, which covers all of the effects modeled by the program, provides a series of snapshots of the effects of various controls over time. The snapshots are obtained by appropriately modifying the input data to a conventional Newton-Raphson load flow. The modeling performed and the modifications of a conventional load flow to provide each snapshot are discussed
