A comprehensive approach for adequacy and security evaluation of bulk power systems

A new approach is described for assessing the adequacy and security of bulk power systems. The method takes into account generation and transmission failures, load variation, generation economic dispatch, security limits, maintenance schedules, the control actions implemented in emergencies. and the impact of different operating schemes. Reliability indices for generation adequacy, transmission adequacy, and system security are defined. The proposed method is demonstrated by application to the IEEE Reliability Test System (RTS). >
