MILP-based Service Restoration in Prosumer-based Active Distribution Networks

The distribution systems may experience damages initiated by various events, which could result in extended network failures. These failures threaten the reliability of distribution systems and negatively impact prosumers satisfaction, and finally cause economic losses. Respectively, one of the most important issues of future distribution systems is managing failures in the presence of energy-trading plans in which prosumers participate to gain profit. In order to effectively reduce the economic losses caused by system outages, this paper proposes a two-stage Service Restoration (SR) model for prosumer-based distribution systems. The proposed model coordinates prosumers through switching and network reconfiguring (NR) in the first stage and then reschedules them and revises energy trading adjustments in the second stage. The objective functions defined in each stage are modeled as a MILP-based optimization problem. The developed simulation is conducted on the IEEE 33-bus test distribution system to evaluate the efficacy of the proposed strategy, where the results show the benefit of the developed model in improving the reliability of the system.
