This paper investigates the role of feasible initial guesses and large consensus-violation penalization in distributed optimization for Optimal Power Flow (opf) problems. Specifically, we discuss the behavior of the Alternating Direction of Multipliers Method (admm). We show that in case of large consensus-violation penalization admm might exhibit slow progress. We support this observation by an analysis of the algorithmic properties of admm. Furthermore, we illustrate our findings considering the ieee 57 bus system and we draw upon a comparison of admm and the Augmented Lagrangian Alternating Direction Inexact Newton (aladin) method.
