A common modeling platform for the multiphase analysis and simulation of modern distribution systems in offline and distribution management system applications

The interconnection of distributed resources to unbalanced distribution systems, the increasing availability of more precise network data, and the need for accurate modeling of networks from subtransmission level to meshed secondary levels in dense urban areas require comprehensive analysis and simulation tools. This paper demonstrates a common solution platform in a compact form for the analysis and simulation of complex distribution networks by integrating the recent research efforts in the field, and discusses new avenues for improvement. The modeling approach is general, in multiphase frame and can be applied to all power system network levels. It creates a universal platform for all types of analysis commonly used in offline tools such as short circuit, fault flow, load flow and harmonic analysis. In addition, the modeling approach is also applicable to multiphase state estimation which is an essential part of Distribution Management Systems. The performance and validity of the method is demonstrated with very large scale and realistic distribution systems.
