Abstract

This paper proposes an approach to congestion management in a deregulated transmission system. In heavily congested conditions, physical transmission congestion can be relieved by curtailing a small portion of nonfirm transactions. Resultant marginal cost-based electricity prices should drastically decrease. Simple and transparent indices are introduced so that both load and supplier can express their levels of acceptance with the congestion management process, and the system operator can select the most effective and desirable congestion relief measures. The proposed approach is tested on a modified IEEE 30 bus system.
