POWER SYSTEM STATIC SECURITY CONTROL

SECURITY CONTROL OF POWER SYSTEMS INVOLVES THE MONITORING OFTHE SYSTEM STATE, THE EVALUATION OF SYSTEM VULNERABILITY TO POTENTIAL DISTURBANCES, AND CONTROL ACTION CALCULATED TO CONSTRAIN THAT VULNERABILITY TO AN ACCEPTABLE LOW VALUE. BECAUSE OF THE PERVASIVE UNCERTAINTIES IN THIS PROBLEM, SECURITY CONTROL IN PRACTICE HAS BEEN RESTRICTED TO EMPIRICAL, SOMETIMES INTUITIVE PROCEDURES, SUPPORTED AT BESTBY DETERMINISTIC ANALYSIS OF LIMITED SETS OF SCENARIOS. IT IS PROPOSED TO DEVELOP A FIRST APPROXIMATION TO A STOCHASTICSECURITY CONTROL REGIME UTILIZING RECENTLY DEVELOPED TOOLS FOR RAPID EVALUATION OF SYSTEM SECURITY AND OF SYSTEM RESPONSE TO CONTROL ACTIONS.
