Available Transfer Capability (ATC) Determination in a Competitive Electricity Market Using AC Distribution Factors

摘要

This article presents the development of a simple and non-iterative method to calculate available transfer capability (ATC) for a transmission system using a new set of distribution factors. Sets of power transfer distribution factors and voltage distribution factors have been obtained using the sensitivity based approach for system intact, as well as contingency cases, and utilized to check line flow limits and voltage limits during ATC determination. The accuracy of these distribution factors have been established with respect to full NRLF results and ATC results have been obtained for bilateral and multilateral transactions on IEEE 24-bus Reliability Test System (RTS) system and a 75-bus Indian system network.
