Coordinate voltage control in active distribution network

The access and management of dispersed energy resource(DER) in active distribution network(ADN) enable coordinate voltage control (CVC) to control voltage actively in distribution system. This paper highlights the impacts of DER on the voltage profile and control strategies of existing distribution network. Accordingly the CVC control framework and strategy in ADN is proposed, which is to make full use of distributed resources or other voltage regulate devices to realize closed loop control of voltage in real time by means of CVC controller in ADN. At last, the study case can verify the effective ness of the CVC strategy in ADN.
