Simultaneous Power Interchange Capability Analysis

A procedure has been developed to determine the maximum simultaneous power interchange capability into a company (area) from its neighboring companies. The optimal combination of scheduled transfers with the neighbors to provide the maximum import is determined. The procedure identifies the outages and the facilities which limit the transfers. The new Interchange Capability Program (INCHCAP) developed at Commonwealth Edison Company and the optimizing technique f Linear Programming are used. Both transmission and generation limitations are considered.
