Abstract

An expert system is developed for emergency operation of power system restoration in a sub-control center. The proposed method restores the blackout area in a power system by using sensitivity analysis and heuristic rules. The rules are categorized into flow-control rules, energization rules, line switching rules, load shedding rules, and voltage correction rules. The switching (opening, closing) of transmission lines, transformers and shunt capacitors, and the load shedding are used for the emergency operations in this paper. For the real time recognition of the network topology, the power system components are represented in hierarchical data structure
