Proposing a Framework for Resilient Active Distribution Systems using Withstand, Respond, Adapt, and Prevent Element

Abstract

The increasing frequency of natural disasters and man-made attacks have increased power outages worldwide. Thus, a resilient infrastructure must be constructed to reduce power system damages which directly impacts on the social and economic lives of people. In this paper, a new framework called withstand, respond, adapt, and prevent (WRAP) is presented to evaluate and improve the resilience of distribution networks following a review on existing studies. This resilience enhancement may happen through microgrid and multimicrogrid development in planning or operation stages. Each element of the WRAP framework is responsible for the improvement of the power system resilience in terms of its own attributes and resilience evaluation index. Furthermore, the WRAP framework is defined on the basis of a flowchart with respect to conditional statements. The WRAP framework can be a helpful solution in measuring the resiliency of the power system in terms of robustness, rapidity, adaptability, and predictability. Finally, a case study considering energy-notsupplied as a resilience evaluation index is presented.

Microgrid‐based resilient distribution network planning for a new town

“…However existing works on hardening context consider transmission grids and rarely studied the electric distribution grid [1][2][3][4]. To improve service availability, multiple restoration algorithms are developed and extensively studied in the literature to enhance system resiliency [5][6][7]. Based on the IEEE Standard 1547.4, clustering the electric distribution network into multiple MGs can improve the system characteristics.…”
