Abstract
A specialized strategy to enhance the resilience of distribution systems against high-impact and low-probability events is developed by incorporating investment decisions and emergency operational actions. Investment decisions involve the optimal distributed generation (DG) allocation, while operational actions include dynamic restoration plans that consider microgrid formation, network reconfiguration, and the pre-positioning and displacement of mobile energy storage systems. The resilience problem is formulated as a mixed-integer second-order cone programming (MISOCP) model, where the investment cost of installing new DG units in the system and the expected value of energy shedding in the system are simultaneously minimized. The MISOCP model is extended to a two-stage stochastic scenario-based approach to address the uncertainties associated with solar irradiance, demand, and fault events. In addition, this formulation captures load changes in response to voltage fluctuations through a voltage-dependent ZIP model, which accurately represents the composite load characteristics as a combination of constant impedance (Z), constant current (I), and constant power (P) components. The effectiveness of the proposed model is demonstrated through several experiments using the 33-node and the 69-node distribution systems under different study cases. Numerical results show the benefits of simultaneously addressing the planning and restoration problems, especially when considering emergency scenarios.

期刊介绍:
IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest.
IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on:
Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals.
Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering.
Development of new or improved fabrication or manufacturing techniques.
Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
