  7. Abstract:
  8. The constant and proper functioning of data center infrastructures is considered a vital element in the modern processing of data and information. Failure in the electricity supply system is the key reason for workload processing stalls in data centers. Energy supply systems, therefore, need to be highly reliable in terms of adequacy and security. Nonetheless, data centers tend to become volatile and, to some degree, unresponsive in the face of a multitude of such errors occurring simultaneously which in turn could lead to higher rates of processing interruptions. Recent years have witnessed an increase in the number of natural occurrences with high impact and low probability (a.k.a., HILP events) and, due to elevated sensitivity with respect to the infrastructure’s proper functioning, there has been a surge in the study of resilience attributes of said systems. The power distribution system is normally taken as the primary source of energy supply for the data center, while its proper functioning during an emergency can hugely benefit the data center infrastructure regarding resilience. Conversely, a data center associated emergency power capacity can intervene—and hopefully better—the power distribution grid resilience. Inasmuch as the interrelation of the data center and power distribution system is ever present, a credible evaluation of the resilience of the former would necessarily entail a careful treatment of the latter. This study puts forth a 7-stage framework for evaluating—thereby also improving—the data center resilience vis-á-vis the earthquake event, while concurrently enhancing that of the power distribution system against the same event. The process begins with a simulation of the consequences of earthquake through a method developed here, and proceeds on to find the optimal plan for workload distribution among three focal points, namely, the power distribution system operator, the internal data center operator, and the central data center operator, through sending communication signals back and forth to decide the optimal recovery plan and dispatching repair teams to restore the data center supply system and the power distribution system in such a way as to meet the goal of simultaneous resilience enhancement. The proposed framework is then applied to the 37-bus IEEE distribution system and a redesigned, Isfahan-based SC1 data center. The results indicate efficacy for the model in resilience enhancement of both the data center and the power distribution system
