Besides the use of analytical programs heuristic knowledge has to be applied for an extended optimization of the operating state of a power system. The concept for a hybrid expert system is developed which performs a search through the space of the feasible operating states. With the combination of a standard search algorithm with a production system a sophisticated search process is built up. Thereby integrated analytical programs provide the knowledge base with quantitative informations aboiit the network state and about the effects of control actions on the network state.An example is given in the application of the expert system for security enhancement. The obtained results are presented, followed by a comprehensive discussion about the effects of the variation of heuristic parameters on the search process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
