Abstract

This chapter describes a generalized frequency response model suitable for the analysis of a power system in the presence of significant disturbances and emergency conditions. The effects of emergency control/protection dynamics are properly considered. Under frequency load shedding strategies are reviewed and decentralized area-based load shedding design is emphasized. The potential benefits of target load shedding compared to more conventional shared load shedding approaches are examined using simulation of a three-control area power system. Finally, the necessity of using both voltage and frequency data, specifically in the presence of high penetration of RES, to develop an effective load shedding scheme is emphasized.
