Sociotechnical Network Analysis for Power Grid Resilience in South Korea

Figure 3

Aggregate criticality scores for Korean power grid infrastructure by emergency management region. The top left image of Korea presents the amount of generation and substation buses located in each region (a), where all other images show the normalized total criticality score for each region (b, c, and d). Thus, percent scale refers to quantity of infrastructure (a) and aggregated criticality score (b, c, and d). Regions are labelled in (a) with abbreviations: Gyeonggi-do (GGD), Gangwon-do (GD), Chungcheongnam-do (CCND), Chungcheongbuk-do (CCBD), Gyeongsangnam-do (GSND), Gyeongsangbuk-do (GSBD), Jeollanam-do (JND), Jeollabuk-do (JBD), Seoul-si (SS), Incheon-si (IS), Daejeon-si (DJS), Gwangju-si (GS), Daegu-si (DGS), Ulsan-si (US), and Busan-si (BS).
