“…The main objective of the system restoration is to restore the out of service loads by transferring the power to them through alternative paths with minimum losses or to transfer these loads to other feeders. Due to delays in the outage processing and the required time for service crews, an outage time from minutes to several hours might be yielded [2]. This slow response in service restoration of conventional distribution networks remarkably affects the system reliability.…”

“…After the fault isolation, the Distribution Network Operator (DNO) reconfigures the distribution network to restore the outage (i.e. system restoration process) [2]. The main objective of the system restoration is to restore the out of service loads by transferring the power to them through alternative paths with minimum losses or to transfer these loads to other feeders.…”

Abstract. This paper proposes a new algorithm for optimum self-healing restoration of a smartmicrogrid operating in islanded mode of operation. The objective of the proposed algorithm is to optimize the topological structure of the islanded microgrid system (IMG) via: (1) maximizing the served load after the fault isolation; and (2) minimizing the switching operation costs. The proposed algorithm takes into consideration the system operational constraints in all operating conditions. The new algorithm accounts for droop controlled IMG special operational characteristics. The problem is formulated as a multiobjective optimization problem and solved using Ant Colony Optimization Algorithm. The proposed algorithm has been implemented in MATLAB environment and several case studies have been carried to test its effectiveness.

“…Power restoration schemes help distribution system operators to effectively restore power automatically or semi‐automatically during emergency conditions such as faults or outages, through temporary feeder reconfiguration [1]. One of the critical aims of these schemes is to ensure that operational and engineering constraints are not violated [2, 3]. In literature many methods are proposed for doing power restoration analysis.…”

“…Several new DER technologies can be considered in future power systems, namely the Distributed Generation (DG), the Demand Response (DR), the electricity storage systems, the Electric Vehicles (EVs) and new players, as the case of Virtual Power Players (VPPs) which should ensure a reliable, secure, and flexible operation of smart grids (Fang, et al, 2012; . The use of distribution network as a resource should be possible considering the use of remote control devices allowing the system reconfiguration or power flows control, limiting or avoiding situations of congestions (Oualmakran, et al, 2011).…”
