Voltage assessment method for zonal distribution networks considering reactive power support capability

Le résumé fourni par la source

To address voltage fluctuation issues in distribution networks (DNs) with high-penetration renewable energy integration, this paper proposes a zonal voltage assessment method considering reactive power support capability. Firstly, an evaluation index system for zonal Voltage Operating State (VOS) is established, incorporating various reactive power compensation devices and regional reactive power requirements. Subsequently, a novel pattern recognition method combining fuzzy identification and Dynamic Time Warping (DTW) is developed, where each indicator is fuzzified using membership functions to transform the zonal VOS assessment into a fuzzy sequence pattern recognition problem, with comprehensive evaluation achieved through DTW distance measurement. Simulation results demonstrate the effectiveness and objectivity of the proposed method.
