Abstract :
A method for the decentralised solution of the DC load flow (DC-LF) problem of large, multi-area power systems is presented. The method transforms the original large set of the linear, sparse DC-LF equations into a number of smaller sparse quadratic programming (QP) problems, one for each area, which are iteratively solved using the auxiliary problem principle (APP) until they converge to the original problem solution. The applications of the decentralised DC-LF solution to the decentralised management of large, interconnected power systems by coordinated transmission system operator (TSO) actions are discussed. Test results on the IEEE-RTS 96 (up to five areas) are presented.
