Resilient post-disaster system reconfiguration for multiple energy service restoration

In this paper, a reconfiguration model for load restoration in radial distributed systems which includes multi-ple energy service is proposed, in which local combined heat and power (CHP) plants can generate electrical and thermal power to meet the demand of critical loads during post-disaster. Maximization of total load restoration has been addressed. After sectionalization by using spanning tree, each microgrid can be fed by one CHP plant to satisfy maximum self-adequacy. Based on the modified IEEE 33-bus radial distribution network, different case studies have been implemented and the proposed model have been validated to be effective. With the proposed model, local CHP generation units can be optimally utilized to restore critical loads with multiple energy requirements, thus catastrophic impacts of the natural hazards on both electrical and thermal energy service can be further minimized.
