Abstract
- This paper presents a situational-aware, data-driven, and agnostic-coordinated control methodology for voltage regulation in the active distribution systems (DS) considering voltage source converters (VSCs) as reactive power sources that work in conjunction with the existing legacy controllers. The approach uses time-scale coordination based on regulator warnings such that the voltage support from regulators is time separated from the reactive power support using VSCs. Two type of voltage changes are considered; a slow changing one based on the feeder load and a fast-changing one based on sudden changes in load or PV output. The reactive support for both these changes is then designed based on the voltage to reactive power sensitivities. The combined reactive support is then used as a set-point to dispatch reactive power from the VSCs. The proposed control technique has been tested in the field verified model of a real feeder and the scalability is verified on an 8500-node real feeder. Results show that the proposed coordination approach has major economic as well and power quality benefits in the operation of DS. It has also been shown that this can be achieved without major changes in the communication framework currently utilized by the utility. [ABSTRACT FROM AUTHOR]
