Electricity Transmission: An Overview of the Current Debate

Electricity transmission has emerged as critical for successfully liberalising power markets. This paper surveys the issues currently under discussion and provides a framework for the remaining papers in this issue. We conclude that signalling the efficient location of generation investment might require even a competitive LMP system to be complemented with deep connection charges. Although a E...

A Multi-objective Transmission Expansion Planning Strategy: A Bilevel Programming Method

This paper describes a methodology for transmission expansion planning (TEP) within a deregulated electricity market. Two objective functions including investment cost (IC) and congestion cost (CC) are considered. The proposed model forms a bi-level optimization problem in which upper level problem represents an independent system operator (ISO) making its decisions on investment while in the l...
