Device-equipment-system Level Power Supply Reliability Evaluation Strategy for Power-electronic-enriched Distribution Networks Considering Typical Mission Profiles
摘要
Abstract
The integration of power electronic devices exacerbates the uncertainty of fault evolution in distribution networks,while traditional power supply reliability assessment methods fall short in characterizing the degradation and failure behavior of these devices,leading to deviations in system reliability evaluation results.To address this issue,this paper proposes a multi-level power supply reliability assessment strategy for power-electronic-enriched distribution networks,oriented toward typical mission profiles.First,a data-physics fusion-driven method is developed to evaluate insulated gate bipolar transistor(IGBT)lifetime damage.The method employs the FFT-LightGBM approach for junction temperature calculation and applies an analytical IGBT lifetime model to compute damage,significantly improving the efficiency and accuracy of lifetime damage estimation.Second,an IGBT reliability evaluation method considering mission profile uncertainty is proposed,in which the wasserstein generative adversarial network with gradient penalty(WGAN-GP)algorithm is utilized to model the uncertainty of mission profiles,thereby reducing its impact on reliability metrics.Third,a comprehensive multi-level reliability assessment framework is established,bridging micro-level device reliability modeling and macro-level system reliability quantification.Finally,the effectiveness of the proposed strategy in accurately assessing the power supply reliability of power-electronic-enriched distribution networks is validated using the IEEE RBTS BUS6 F4 distribution system.关键词
