A decentralized Volt/Var Optimization scheme for smart distribution systems

摘要

This paper considers the use of inverter interfaced distributed generators (DGs) for Volt/Var control in a distribution system with high penetration of DGs. A new decentralized Volt/Var Optimization (VVO) scheme is proposed to facilitate Volt/Var control for such a case. The proposed method is based on the Dantzig-Wolf decomposition and the paper shows that this approach facilitates dividing the distribution system into subareas where a local controller can be assigned. The effectiveness of DW-based decentralized VVO scheme is tested using the IEEE 34 node test feeder with high penetration of DGs.
