Analysis of DSM´s impacts on electric energy loss in distribution system using VPI model

This paper presents a novel proposal for quantifying the influence of Demand Side Management (DSM) objectives on electric energy loss in distribution system. DSM objectives are modeled by VPI model and the testing results prove its suitability, especially for analysis on energy loss in distribution system. This paper uses IEEE´s 34 Node Test Feeder as the test system for energy loss calculation and the analysis of DSM´s influences. Network modeling is made using PSS/ADEPT 5.0. The research uses typical daily load curves of industrial and residential loads in Vietnam as a case study. Results not only indicate the effectiveness of loss reduction in DSM peak-clipping and load shifting, but also recommend DSM strategies for the best effect on energy loss reduction basing on modeling error testing.
