A Robust Incremental Volt/VAR Control for Distribution Networks

This paper proposes an incremental Volt/VAR
control for voltage regulation in distribution networks
with high penetration of distributed energy resources. The
Volt/VAR controller coefficients are obtained by solving a
robust optimization problem, where reactive power is minimized.
The proposed optimization problem is solved using a
Successive Convex Approximation method. Communication
requirements are minimal and restricted to the offline stage
since the local controllers share the same gains. Numerical
studies on a 42-node low voltage network demonstrate the
improved performance of our local controllers against a
traditional static Volt/VAR control strategy.
