Integrated Volt/Var Control Method for Voltage Regulation and Voltage Unbalance Reduction in Active Distribution Networks

The emergence of distributed generation such as solar systems has introduced new challenges in distribution networks that are becoming more apparent with increasing penetration levels. time mismatch between peak load and can make voltage levels swing towards extreme limits during a day. Distribution network service providers struggling to cater for installations while ensuring the quality steady state supply meets stipulated requirements. segregation medium low control strategies may result unnecessary or worse, opposing actions leading issues on one side influencing other. By developing an efficient volt/var method, level unbalance comprehensive be controlled simultaneously. This paper analyses whole, unabridged problem. proposes pragmatic effective method addresses regulation simultaneously using existing infrastructure. proposed is implemented three types representative Australian results obtained demonstrate manage whilst reducing number tap change operations maximizing penetration.
