Determining Feasible Region of Tie-line Transmission Considering Power Loss

Power supply is geographically located in the opposite direction of power demand in China. Consequently, tie-line power exchanges in interconnected power grids are common. A good description of the feasible region of tie-line transmission can improve utilization efficiency of power resources. In this paper, one two-stage determination method for the feasible region of tie-line power transmission with power loss is presented. Furthermore, in order to reduce the number of optimization in our two-stage method, an acceleration strategy is further presented based on hot-start operation point. The validation and effectiveness of the presented methods are demonstrated in the IEEE 14-bus and IEEE 300-bus test systems.
