Distributed algorithm of multi-region active load in power system economic dispatch

Along with the enlarging of electric network the problems which longtime computing and slow rapidity of convergence become serious in the electric network computing. In order to cope with the problems, this article utilize distributed parallel optimization model which based on sub-area division and auxiliary problem principle (APP) to solve multi-region active load in economic dispatch. We regard the virtual generator as verity generator, and deduce its cure of consumption characteristic. Finally, we give a simulation of example, the simulation shows that this method is fast and has a good convergence property.
