Security Enhancement System (SES) is a set of integrated network analysis software programs that provides a means for improving system security and economic operation. SES consists of two major functions; Contingency Analysis and Security Enhancement. Contingency Analysis examines the effects of selected contingencies on system operating conditions. Contingencies are the loss of one or more network components (i.e., transmission lines, transformers, and generators), or the opening and closing of switching devices. Contingency Analysis provides information about those outages, identifying which will cause violations of the operating limits of equipment or of the system, and cause system separation or isolation of load or generation. Security Enhancement recommends corrective actions to alleviate thermal and voltage violations, e.g., rescheduling real power generation, committing and operating fast start units, changing phase shift angles and transformer taps, switching shunt capacitors and reactors, changing generator regulated voltages, and switching bus tie lines and breakers. Security Enhancement recommends corrective actions for existing violations. Corrective and preventive actions are developed for contingencies found to cause violations during Contingency Analysis. Recommendations are based on the least cost set of control actions required for alleviating violations. Advanced techniques were developed during the project for determining the external model, contingency screening, and network reduction. Models used throughout SES were derived from the fast-decoupled power flow techniques that allow SES to be used in real-time. SES can also be used in the study mode to study network changes and contingencies. 26 refs., 7 figs.
