Multi-station Integration-Based Coordinated Control for Voltage Support in Active Distribution Network

With the incereasing penetration of distributed generaitons (DGs), regulations of voltage along feeder lines in active distribution network (ADN) are becoming unprecedentedly challenging. Fortunately, technological advances in distributed energy resources (DER) provide promising and powerful ways to cope with these challenges. In this paper, we propose a coordinated control scheme for voltage support in ADN based on multi-station integration, which integrates various DER stations as an integrated station (IS). First, we study the voltage impact mechanism of IS. Then we put forward a local and node-centered topology information model, and propose a distributed adaptive voltage-reactive power control approach, and an expanded voltage-reactive power control approach for backup. Finally, the feasibility and effectiveness of the proposed scheme are verified by Matlab simulation.
