This paper discusses experiences in the use of online stability analysis tools in Electric Reliability Council of Texas (ERCOT) interconnection, USA. In order to prevent certain unstable system conditions, the online stability analysis tool - DSATools - has been implemented in the ERCOT control room. Using real-time information from the Energy Management System (EMS), DSATools calculates the system...
Many interconnected power systems are constructed to meet the ever increasing electric power transfer demand. A disturbance anywhere in such an interconnected system will directly influence the power transfer capability of major transfer interfaces, as well as the transient stability of the system. Instead of monitoring the power transfer limit on a given interface, we propose a real-time synchrophasor...
