Top1. Introduction
The increase of distributed energy resources (DERs) and the paradigm shift from automated meter reading to advanced metering infrastructures (AMIs) (Kabalci, 2016; Muscas, Pau, Pegoraro, & Sulis, 2015; Parhizi, Lotfi, Khodaei, & Bahramirad, 2015) may be seen as the fundamental drivers for various design or methodological approaches to find optimal solutions regarding smart grid (SG) reliability and resilience issues including topological design patterns like micro grid (MG) decompositions (Cox & Considine, 2013; Melike, Burak, & Hussein, 2011). The common perception of the principles of power management and control within a SG typically restricts to a hierarchical framework consisting of control mechanisms focusing on voltage and frequency stability as well as economic considerations (Ahumada, Cardenas, Saez, & Guerrero, 2016; Parhizi et al., 2015). These control mechanisms are important pillars of a reliable power distribution system. Resilience aspects of power systems applying SG technologies are moving more and more into the focus of scientific investigations - where especially smart solutions are considered as one crucial building block for power system resilience (Panteli & Mancarella, 2015; Venkata & Hatziargyriou, 2015).
The smart meter roll-outs are accompanied by critical public debates which are essentially related to fundamental security worries and the generally noticed increased vulnerability due to undesired manipulations from external parties, see for example (Aloul, Al-Ali, Al-Dalky, Al-Mardini, & El-Hajj, 2012; Goel, Hong, Papakonstantinou, & Kloza, 2015).
The concept of urban resilience encompasses various types of resilience dimensions such as the social, economic or physical infrastructure dimension (Bruneau et al., 2003; Cimellaro, 2016; Renschler et al., 2010). Critical infrastructure (CI) services such as the supply of electricity, drinking water, and health care provide vital services for the population. Thus, disruptions or failures of these services are hazardous and can lead to injuries or even losses of life, property damages, social and economic disruptions or environmental degradations. Therefore, CIs constitute a pivotal aspect in urban resilience considerations - establishing and implementing sophisticated continuity management (CM) concepts with respect to CIs may be regarded as one of the major factors for preserving or enhancing urban resilience. Most of the CIs like water supply, hospitals, pharmacies, and traffic- and transport systems rely on electricity. The circumstance of massive dependencies of other CIs to electrical power entitles the electrical power grid to be considered as a high ranked CI. But also, the provisioning of electricity to other physical infrastructures especially including households and companies constitutes to urban resilience. Approximately 99% of all enterprises are small or medium enterprises (SMEs) (Thiel & Thiel, 2010). Light weighted Business Continuity Management (BCM) strategies for SMEs are requested (Reuter, 2015). A future decentralized power distribution system, applying smart infrastructures, can enable more refined and smart power distribution mechanisms as a basic strategy to mitigate the impact of power scarcity (Liu, 2015; Panteli & Mancarella, 2015; Venkata & Hatziargyriou, 2015).
