This paper discusses a technique to implement Remedial Action Schemes (RAS) or Special Protection Systems (SPS) for Variable Transfer Limits (VTL) computation. Need for RAS implementation for VTL calculations are discussed. The technique presented can be applied to the bus/branch model as well as for the node/breaker model. Advantages of using the State Estimator cases for VTL calculations are discussed...
This paper discusses need for Variable Transfer Limits in the Northwest. The paper presents a novel method to compute Variable Transfer Limits (VTL) using the node/breaker model State Estimator (SE) cases. Advantages of using the node/breaker model for VTL calculations are discussed. A detailed 6 step process to compute Variable Transfer Limits are presented. Interesting sample results are presented...
Increasing installations of large amounts of renewable generation are contributing to a transition of the Electric Power industry operating model away from base loaded generating resources and power transfers between Balancing Authorities (“BAs”) that are generally fixed for an hour. In contrast, Variable Energy Resources can change generation many times within an hour. In addition, when wind generation...
