Popis:	As the fast expansion and interconnection of power system, it makes higher requirements for Optimal Power Flow (OPF) calculation in modern power grid. A distributed coordination and optimization method is presented in this paper. Injection power equivalent of sub-system boundary bus is utilized to solve multi-area dispatching problem. Based on regional decomposition model, it decouples the integrated optimization and avoids complex computation of system parameters equivalent in conventional methods. Besides, it reduces the communication between different regions. The nonlinear primal-dual interior point method is used for optimization in each sub-system, outer coordination of boundary bus’s voltage correction is conducted to compute the optimized dispatching in the whole interconnected power system. Numerical simulations are taken in IEEE test systems. The results show that the proposed method is validated, effective and suitable for online application.
