Abstract

As two effective ways to enhance power system reliability, self-healing control and microgrids have been implemented in advanced distribution systems. This paper presents a quantitative approach to assess the benefits of deploying self-healing control and/or a microgrid in improving distribution system reliability. The proposed method utilizes time-sequential Monte Carlo simulation method and further integrates the service restoration and three-phase power flow constraints to accommodate practical distribution system complexity. To reduce the computation burden in searching for optimal service restoration strategy, this paper proposes a heuristic algorithm to find a practical service restoration strategy according to the topology constraints and the constraints of three-phase power flow. Tests on a four-feeder distribution system show that both the system-level reliability and the critical load level reliability are significantly improved after deploying the self-healing control and microgrid.
