One frequently discussedconvexdistributed optimization method is the Alternat-ing Direction of Multipliers Method (ADMM)[3],whichisalsoappliedincontextofAC OPF[1,4,5].ADMMoften yields promising results even for large-scalepower systems [4]. However,ADMMsometimes requires a specific partitioningtechnique and/or a feasible initialization in combination with high consensus-v…
