A Method of Determining Target Configurations for Power System Restoration by Means of Linear Programming

When electricity supply is interrupted due to a fault, it is of primary importance to restore the power system promptly according to an adequately planned restoration procedure. Recently, power system restoration problems have received much attention in the literatures.This paper proposes an efficient restoration procedure by making use of the linear programming. in which a restoration problem is formulated as a minimum cost flow problem and solved by the LP algorithm. Assumptions postulated in this approach are: (1) the priorities in restorative operations have been mapped on to the costs of branches, (2) available power sources are allocated to source nodes, and pre-falut loads to sink nodes, and (3) the optimal restorative plan is decided from a solution of the optimal flow.The proposed approach has been applied to the practical power system restoration problem, resulting appropriate solutions.
