This paper proposes a multiobjective distribution optimal power flow formulation to improve the resiliency of distribution feeders. A systematic approach to size and locate smart inverter (SI)-based distributed energy resources (DER) with optimal Volt-VAr droop based on the IEEE 1547-2018 is presented. The integration of the SI's optimal droop is very important since these extreme weather events could lead to the loss of other legacy voltage control devices. The proposed formulation incorporates a unique critical infrastructure (CI) ranking scheme to prioritize the CI nodes for optimal DER placement. The formulation also ensures maximum hosting of the DER and uses the optimal Volt-VAr control droop for effective voltage regulation during extreme events. An extreme event caused by a hurricane is simulated on an IEEE distribution feeder with different probabilities of failures formulated for each section of the lines in the feeder. The mixed integer nonlinear programming formulation aims to maximize the penetration of the DERs, improve the network resiliency, and minimize the overall network losses while satisfying all network and power flow constraints. The Pareto optimal solutions (POS) of the results show the various possible locations of the DERs and the trade-off in the base resilience, DER hosting capacity, and the increased active power loss in the network. The results also show the respective optimal SI Volt-VAr droop associated with the POS that ensures effective voltage regulation.
