چکیده :

Reclosers and sectionalizers (RSEC) are automatic switches that can significantly improve the reliability of radial distribution systems (RDS). However, the optimal siting of these switches has a rejuvenating effect on minimizing the cost to the benefit of the electric distribution companies. This paper proposes a three-stage optimal RSEC placement for reliability improvement and readjustment of the affected protection settings in an RDS. The first stage presents a graph-theory-based network reduction scheme to confine the candidate locations for RSEC placement. An objective function is defined in the second stage based on reliability indicators including ENS, SAIFI, and SAIDI to evaluate the eligibility of each response. Additionally, the investment costs and maximum acceptable budget from the company's point of view are considered in the function. The slime mould algorithm (SMA) solves the fitness function. In the last stage, the alterations required to modify the protection settings are applied to ensure the restoration of coordination of all protective devices. The proposed method is implemented on IEEE 85-Node as a standard RDS and F5-BostanAbad East Azerbaijan as an actual RDS, and the results show the effectiveness of the proposed scheme.
