The Realization of a Highly Modulized Open-Ended Distribution System Comprehensive Planning Platform Compatible with CIM Model

Abstract

This paper introduces key features and the structure of a distribution network comprehensive planning platform as well as the functions and algorithms of core modules. The platform has a number of features, some of which are innovation points: 1) it provides a unified data interface compatible with IEC61968-based CIM model; 2) it adopts an effective algorithm that diagnoses and corrects input data of a relatively poor quality; 3) It converts CIM-based data into data based on calculation models, so that the calculation modules can analyze them. 4) Its reliability analysis module uses an algorithm based on zones. 5) The highly modulized platform has the provision for cloud computation in future. Furthermore, this paper has defined a number of reliability indices based on zones and feeders. The application of the platform in Tianjin urban network has desmonstrated its effectiveness: it successfully corrected data errors with no need for human intervention and yielded satisfactory results.
