TLDR
In this article, a two-layer computational model is proposed to calculate the total transfer capability (TTC) in a multi-area power system, where areas do not necessarily share their network data.Abstract:
A method of calculating the Total Transfer Capability (TTC) in a multi-area power system, where areas do not necessarily share their network data, is described. In a restructured power system, the sellers and buyers of power transactions may be located in different areas. Computation of TTC will then require system-wide studies. This study investigates a two -layer computational model, which takes advantage of the system-wide calculated Power Transfer Distribution Factors (PTDF) in order for each area to calculate its own linear TTC while a central entity coordinates these results to determine the final value. The proposed problem formulation and its solution algorithm are presented. IEEE 30 bus test system is used to demonstrate the approach and numerically verify the proposed TTC calculation method.
