A Flexible Multi-Agent Algorithm for Fast Restoration of Distribution Systems, Compatible with GIS

Power distribution network configuration must be restructured fast after occurring a fault in order to restoring healthy parts. A logical algorithm is needed to do such restoration. In recent years، by developing GIS systems in distribution networks، data entering and structuring in computers has been changed and dissimilar to conventional softwares، computer cannot view the network configuration. In this paper a proper definition of network agents are suggested in matrix format. By such definition fast detection of fault location and deenergized sections located at its downstream parts is done. Also curtailed load is calculated. Finally with digital data available in the GIS databases، optimal restoration strategy is selected and applied based on available routs. The proposed algorithm is applied on a complicated three feeder distribution network to test its effectiveness and speed. Simulations in MATLAB shows that the proposed algorithm is very fast and robust to any complicated network configuration as well as any number and location on sequential faults.
