A New Scheme for Voltage Control in a Competitive Ancillary Service Market

This paper shows how a competitive ancillary service market for voltage control/reactive power might operate and what it might look like, given the eminently local nature of the service. An automatic voltage control would dynamically manage the reactive power available in a certain geographic region and a local market in reactive power could then be developed similarly to that proposed for the load-following ancillary service. Coordination among these regions would be required.
