Research And Application Of Parallel Y_BUS Load Flow Algorithm

With the continuous progress of the electric power system automation,large-scale network algorithm has become demanded.By means of Parallel Algorithm rowing the performance of power flow algorithm,the simulation and real-time analysis of large power system will be improved.Using the principle of Distribution Network Y_BUS Load Flow and Parallel Algorithm,the convergence property of the network buses is analyzed and taking the convergence property as the conditions of network partition,Parallel Y_BUS Load Flow is presented.The impact of asynchronous iterations proportional of the master-slave network on the network convergence is studied.Parallel Y_BUS Load Flow has many advantages such as explicit principle,easy program implementation and fast calculation.Because of not being impacted by the ratio of R/X,it can be applied reliably to distribution system.In addition to this above,the power flow calculation quantity is decreased and the convergence rate is improved.Compared with Y_BUS Load Flow,the results of IEEE examples validate these conclusions.On the background of Anshan distribution automation project,solution is proposed and the management of Anshan electric power system is realized,including the network tomography,power flow analysis and remote monitoring.
