The study of distribution grid distributed self-healing under dynamic operating modes

摘要

Self-healing is the basic characteristics of smart distribution grids, usually using centralized or distributed self-healing. Distributed self-healing act rapidly, can improve the reliability of power supply, but by the way, impact by operating mode, and cannot adaptive suit the distribution grid. This paper analyzes the characteristics of different self-healing model, and analysis the control strategy of distributed self-healing under typical operating modes based on a typical distribution network model. Find out a novel control strategy of distributed self-healing under dynamic operating modes of the distribution network. As a result of the new control strategy, distributed self-healing maintain rapid characteristic and not affected by operating modes. It also has self-adaptive, high reliability, real-time and other good benefits. This control strategy distributed self-healing distribution network operating system under dynamic operating modes can effectively improve power supply reliability.
