Abstract

The alarming number of severe outages that have occurred over the last decades raised the awareness regarding the importance of resilient power systems. As fundamental component of the Smart City concept, the energy infrastructure must adapt to the new challenges in terms of major blackouts, natural or human-caused. In distribution networks, the intentional islanding operation proves itself an efficient solution to maintain the energy supply during emergency conditions, made possibile by the Smart Grid technologies, such as distributed generation and energy storage. However, the limited resources present at the distribution level require a good management strategy, in order to minimize the adverse effectes of a long-term interruption. The scope of this paper is to develop an efficient coordination model of load, generation units and energy storage devices under islanding conditions for a smart distribution network. In this regard, a mixed-integer second-order cone programming (MISOCP) method is approached in order to increase the network resilience based on the unsupplied load minimization, while maintaining proper operational parameters for the IEEE 33-bus test distribution network.
