    • Institute for Nuclear and Energy Technologies Institute for Industrial Production 8 02.07.2013 The Load Reduction Problem Network Instability Drop in Frequency The Risk of Load Reduction R = H * E * V Risk = Hazard x Exposure x Vulnerability The hazard H is the probability of outage of a specific severity. The exposure E describes the Critical Infrastructures at risk in the potential affected supply region. The vulnerability V is the condition of physical, social and economic factors increasing the susceptibility of the functioning of a SR to power outages.

    • Institute for Nuclear and Energy Technologies Institute for Industrial Production 9 02.07.2013 The Load Reduction Problem What are the levels of vulnerability in the supply regions? What kind of critical infrastructures are affected by decoupling selected supply regions? Which supply region should be chosen to be decoupled? How does the vulnerabiltity change when decision maker‘s preferences change regarding single critical infrastructures? Münzberg, Th.; Müller, T.; Möhrle, S.; Comes, T; Schultmann, F. ISCRAM 2013, Baden-Baden Challenges within the Load Reduction Problem Avoiding and minimizung the effects of power outages to an affected area Control a drop in frequency by load reducing Needs to support decisions Developing a clear and well- structured framework to assess socio-economic vulnerabilities Faciliating the integration of all involved stakeholders to the decision making process Assessing and ranking the levels of vulnerabilities of supply regions against power outages 1 2 3 4

    • Institute for Nuclear and Energy Technologies Institute for Industrial Production 17 Conclusion The assessment of supply region‘s vulnerabilities is essential for emergency management and the collaborative preparedness against power outages. The vulnerability of supply region can be assessed by an integrated multi-criteria approach taking economic, social and physical impacts into account. The approach enhances understanding the consequences of power outages. The display of levels supply region‘s vulnerabilities can be used for vulnerability- triggered load reduction in disaster risk management. Data collection as well as the criteria weighting process need collaboration between EMA, CI providers and stakeholders. This supports inter-organizational partnerships for CI protection. Future Research Directions Analysing uncertainties (e.g. indicator selection and standardization) Consideration of dynamic aspects resulting from (1) time limited resilience capacities and (2) propagation of consequences by interconnected infrastructures 02.07.2013 Münzberg, Th.; Müller, T.; Möhrle, S.; Comes, T; Schultmann, F.
