Reactive Support and Voltage Control Service: Key Issues and Challenges

This paper reviews the nature and salient characteristics of reactive power support provision and voltage control issues in electricity markets. The major challenges in the provision of such services from the generation units under both normal and emergency conditions are highlighted. The key issue of assessing the value of the reactive support is addressed. Some key problems and challenges in the adoption of market mechanisms for reactive power support services are discussed. This paper serves as an overview of the challenges that need to be resolved in effectively managing and pricing reactive support and voltage control services
