Zusammenfassung:	Apparatus and methods are disclosed for performing voltage management in a power grid by engaging distributed energy resources (DERs) to source or sink reactive power. An administrator can produce a demand curve relating demanded quantities of reactive power for an upcoming interval to corresponding marginal prices the utility will pay for the quantities. Controllers of one or more DERs electrically coupled to the power grid can produce a supply curve relating offered quantities of reactive power for the upcoming interval to marginal prices the DER will accept to supply the quantities. A coordinator controller can determine a clearing price and quantity for reactive power for the upcoming interval based on the demand and supply curves and cause the one or more DERs to collectively dispatch the clearing quantity of reactive power to the power grid during the upcoming interval.
