Query: Scalable Distributed Non-Convex ADMM-based Active Distribution System
  Service Restoration   Distributed restoration can harness distributed energy resources (DER) to
enhance the resilience of active distribution networks. However, the large
number of decision variables, especially the binary decision variables of
reconfiguration, bring challenges on developing effective distributed
distribution service restoration (DDSR) strategies. This paper proposes a
scalable distributed optimization method based on the alternating direction
method of multipliers (ADMM) for non-convex mixed-integer optimization problems
and applies to develop the DDSR framework. The non-convex ADMM method consists
of relax-drive-polish phases, 1) relaxing binary variables and applying the
convex ADMM as a warm start; 2) driving the solutions toward Boolean values
through a proximal operator; 3) fixing the obtained binary variables to polish
continuous variables for a high-quality solution. Then, an autonomous
clustering strategy together with consensus ADMM is developed to realize the
distributed cluster-based framework of restoration. The nonconvex ADMM-based
DDSR can determine DER scheduling and switch status for reconfiguration and
load pickup in a distributed manner, energizing the out-of-service area from
local faults or total blackouts in large-scale distribution networks. The
effectiveness and scalability of the proposed DDSR framework are demonstrated
through testing on the IEEE 123-node and IEEE 8500-node test feeders.
