Power System Ancillary Services

Part of the Energy Systems book series (ENERGY)

Abstract

Ancillary services are essential for the reliably high-quality operation of a power system. These services are provided by network users and procured by the independent system operator – ISO. Due to system requirements and market structures, ancillary services are managed in different ways around the world. In this chapter, we briefly describe the definition, classification, technical requirements and economic issues of ancillary services. Particularly, we compare active power reserves and reactive support ancillary services in different systems. Finally we show two illustrative examples: A co-optimization model with AC network constraints for the energy and reserve dispatch and a modified version of this model that considers the reactive power dispatch.

Keywords

Active power reserves ancillary services co-optimization dispatch power system reactive support
