Coordinated Volt-Var Control: Online Voltage-Profile Estimation in Smart Distribution Networks

The increasing penetration of intermittent and stochastic distributed generation (DG) sources in the existing power grid can lead to voltage rise problems. Meanwhile, the rapid development of smart grid technologies calls for effective solutions to realize the real-time measurements and coordinated volt-var control to improve the overall systems voltage profile (VP). This article presents online VP estimation and coordinated volt-var control in a smart distribution network with multiple DG systems.
