Zone partitioning is an essential technique for the operation and management of such an interconnected power system. Owing to the transmission capacity limitation, transmission congestion may occur with a regional influence on power system. If transmission congestion is considered when the system is decomposed into several regions, the power consumption structure can be optimized and power system planning can be more reasonable. At the same time, power resources can be Citation: Hu, Y.; Xun, P.; Kang, W.; properly allocated and system safety can be improved. In this paper, we propose a power system zone Zhu, P.; Xiong, Y.; Shi, W.
