“…Thus, all properties of standard BFS procedure applied for balanced (per phase) power flow calculations are kept in GBFS procedure applied for unbalanced networks (mixed irregular ones included). Consequently, dealing with the following effects is taken on from well‐known references: (1) meshes , (2) three‐phase transformers with delta and ungrounded wye connected windings , (3) three‐winding transformers , and (4) underload tap changing transformers (ULTCTs)—load tap changing transformers and voltage regulators, as well as shunt capacitors, which are equipped with local control . Differently from the CI and NR, the GBFS procedure (like BFS) deals with the following in a very simple manner: (1) ULTCTs, (2) capacitor (inductors) banks with local control, (3) mutual couplings, and (4) short line sections, even ones with zero‐valued parameters.…”
