摘要
文中在系列论文上篇介绍电力电子混杂系统多时间尺度分析和控制理论的基础上,进一步介绍其应用。首先从大容量和大规模电力电子系统应用需求出发,阐述电力电子技术应用面临的机遇和挑战;分析和介绍基于数值凸透镜原理的离散状态事件驱动建模仿真方法;分析和介绍基于多时间尺度的主动控制和能量平衡综合控制方法;特别综合展示这些方法在兆瓦级多端口多功能电力电子变压器中的实际应用情况;最后对多时间尺度分析控制方法的未来发展进行展望。
Part I of this paper introduces the multi-timescale analysis and control theory of power electronics hybrid systems,while its applications are further illustrated in Part II.First,the opportunities and challenges of power electronic technologies are analyzed from the aspect of the actual demands of high-power and large-scale converters.Secondly,the discreet state event-driven(DSED)modeling and simulation method based on the numerical convex lens theory is introduced and analyzed.Furthermore,the multi-timescale control methods including active control and energy balancing control approaches are presented.These simulation and control methods are applied to a megawatt multi-port multi-functional power electronics transformer(PET)case to show their efficiency.Finally,the future developments of the multi-timescale analysis and control methods are prospected.
