Abstract

This introductory chapter gives a brief overview of power system coherency and model reduction literature. This survey focuses on both the early results and some more recent developments, and organizes power system model reduction techniques into two broad categories. One category of methods is to use coherency and aggregation methods to obtain reduced models in the form of nonlinear power system models. The other category is to treat the external system or the less relevant part of the system as an input–output model and obtain a lower order linear or nonlinear model based on the input–output properties. This chapter also provides a synopsis of the remaining chapters in this monograph.

This discussion can readily be extended to multiple external systems, as well as some buffer or boundary systems between the study system and the external system.

Note that (1.7) can be shown to be equivalent to the formulation in [17] using the study system boundary buses as inputs and current injected into the study system as the outputs, and maintaining a linearized model of the external system power network.
