The topic of interior point (IP) methods has been one of the most active research areas since it was rediscovered by Karmarkar in 1984. A variety of IP algorithms have been applied to many areas of power systems optimisation. This study presents a survey of literature on the application of IP methods to planning and operation of power systems. A review of research papers that have been published since 1994 in three major power system optimisation problems is presented. The problems are economic dispatch, unit commitment and hydrothermal coordination.
