Abstract: Load transfer is one of effective measures to guarantee the security of power supply under transformer fault or N-1 maintenance. The load transfer scheme obtained by experience is feasible. How to get the optimized scheme rapidly is a critical issue. As to the characteristics of load transfer and the constraints of system security operation, the optimal decision-making model which considers such factors as swiftness, economy and stability is proposed in this paper, and the optimized load transfer scheme is obtained by use of Fuzzy Analytic Hierarchy Process(FAHP), which provides a scientific decision reference for dispatchers. In the end, the feasibility, fastness and effectiveness of this optimized decision-making method for load transfer are verified through an example of a regional power grid.
