Analysis Tool for Assessment of Grid Management Measures Using Time Domain Calculations

In order to compare the impact of passive (like network restructuring) or active (like on-load-tap-changer) grid management measures a novel tool was developed, which performs specific load flow benchmarks tests using synthetic daily load and infeed profiles. In this paper first preliminary results of the analysis of a real urban medium voltage distribution grid with 122 substations using this tool are presented. Examples are given, of how the developed methodology can be used for the assessment of very different grid management measures and operation circumstances. By using the proposed benchmarks, a novel approach for network planning is introduced.
