Abstract

For construction of smart grid with optimal operations, analytical studies for distribution systems are important, and advanced method which is applicable to any power systems is required. Today, Newton-Raphson method is utilized for a lot of power flow analysis. However, since R/X ratios of lines are relatively high in distribution systems, it is said that the convergence characteristics of Newton-Raphson method are poor. In addition, when some bus voltages are close to the voltage stability limit in power systems, the convergence characteristics are worse.
