ABSTRACT:The layout of distributed generation has important influence upon voltage stability in distribution network. Based on continuation power flow method and modal analysis method, and taking reducing the reactive losses within the scope of the safety voltage as the principle, the influence upon voltage change from the different position of distributed generation is researched. The continuation power flow method can accurately and quickly obtain voltage collapse point, and the modal analysis can accurately find out the weak area of the system and the participation degree of the corresponding components. And the optimum interconnection position of distributed generation is chosen based on continuation power flow method and modal analysis. IEEE 33 node system test results show that the new algorithm of the layout of distributed generation is feasible.
