Optimal Power Flow With Step-Voltage Regulators in Multi-Phase Distribution Networks [PDF]
This paper develops a branch-flow-based optimal power flow (OPF) problem for multi-phase distribution networks that allows for tap selection of wye, closed delta, and open delta step-voltage regulators (SVRs).
