Bridging the gap between operation and planning in WECC - A step toward dynamic assessment of system limits

• What is needed for computation of dynamic transfer limits: • Same steady state network models for off line and on line use or at least good mapping tool in between the two so that off line model can be easily and efficiently adjusted to reflect real time operating conditions; • Model of entire interconnection without reductions; • Off-line tools need to be able to support full topology (node-breaker) real time operations model; • What needs to be done: • Improve mapping tool and work further toward reconciling models; • Improve off line tools traditionally used for limit assessments; • We need one single model for SE for interconnection; • Publishing real-time cases so that they can be used in off line environment in near real-time;
