Abstract

Market power has appeared in a power system in conjunction with the deregulation of power industry. Market power problems are more complicated in an electric market than those in a commercial market due to the special properties of electricity. This paper investigates the impact of network constraints and contingencies on nodal market power. A market power index designated as nodal-must-run-share (NMRS) is used to represent market power. The expected-nodal-must-run-share (ENMRS) is applied to include the effect of random failures in transmission network on market power. The IEEE-RTS is analyzed to illustrate the proposed technique.
