Distributed generation is a trend for future development of energy industry. This paper studies the voltage stability of distribution networks with distributed generations. First, distributed generations are classified into four node types according to different network interfaces and operations, and the mathematical processing for each type used in the Newton-Raphson power flow algorithm is discussed. Second, the paper presents a commonly used index in the analysis of static voltage stability of distribution networks. The static voltage stability index based on the existence of power flow solution is discussed, and the relation between this index and load scale factor (LSF) is analyzed. Finally, the load flow algorithm with distributed generation is programmed. Through practical calculation example, the impacts of type, location, capacity and power factor of DG on static voltage stability of distribution networks are studied. The results can provide directions for the planning of distributed generations in distribution network.
