An efficient algorithm for distribution network restoration

This paper proposes an efficient and computationally fast solution algorithm for distribution system restoration based on a mathematical programming approach. The computation time is improved greatly by dividing the problem into two stages and incorporating restoration strategies, which are derived from on operator's knowledge and experience. It is shown from simulation results that this method is able to obtain an optimal target configuration in all cases. In addition, the computation time has been reduced to within 30% of the authors' previous method.
