Voltage security and reactive power management
1 Department of Electronic and Computer Engineering, Brunel University, Uxbridge UB8 3PH, UK
The focus of this paper is on voltage security as a function of ancillary services that can be described in the context of reactive power markets and associated pricing mechanisms. Firstly, an introduction to voltage security and reactive power management is presented and the consequences of recent electricity industry restructuring in the UK are highlighted. Finally, several recently developed algorithmic techniques are presented in detail. The techniques will introduce the concepts of transition-optimization and congestion management in the context of a complete framework for the monitoring, assessment and control of voltage security.
