With the development of digital economy, increasing importance has been attached to the power supply reliability, especially to the temporary interruption. Normally closed-loop operation distribution network with dual sources is discussed,which is the basis of the fault seamless self-healing technology to avoid the temporary interruption. But the power flow distributes naturally and there lack effective power adjusting measures in the traditional distribution system. Although the Unified Power Flow Controller (UPFC) could control the power flow flexibly, the economy becomes its application bottlenecks used in the distribution system. Combining the dispatching request of power flow and the economy of the UPFC apparatus, it presents an optimal power flow control method based on the minimum of the UPFC capacity. The restrained conditions of load node voltage deviation and power limitation of the both-side feeders are considered. Finally the optimization target function is solved by the global optimal method. The simulation result proves the validity of the proposed method.
