Introduction: Everyone is familiar with electronics because of communication (TV, radio, internet, wireless and mobile) and consumer products. But such electronics are limited to low power ranges. Power electronics deal with the mega-watt levels of electric utilities. Hydro-Quebec, for example, is connected to New Brunswick, USA (and Ontario Hydro in the near future) by dc lines for reasons of security. The equipment for converting from AC to DC and back to AC are based on power electronic technology. All renewable energy technologies (wind, photovoltaic, solar, etc. ) require similar equipment from frequency changing (DC to 60 Hz AC, or variable frequency AC to 60 Hz AC). After decades of researching under the theme, "Force commutated high power electronics" to improve power electronic converters in the forms of High Voltage DC (HVDC) stations, and Flexible AC Transmission Systems (FACTS) controllers, the next phase of consists of integrating the frequency changers of renewable energy sources to improve the overall dynamic performance of power grids. The exciting prospect is: when renewable energy sources reach penetration of 30%, the power electronically controllable power (coming from the frequency changers) in the power grid becomes 30% also. Objective: Besides continuing to improve HVDC and FACTS equipment, the added challenge is to use the 30% power electronically control to stabilize and improve the damping of large interconnected power systems whose inter-area oscillations have, in the past, led to blackouts. Scientific Approach: Besides power electronic technologies, the research methods will be extended to small signal stability analysis, application of eigenfunction concepts and computation of eigenfunctions by parallel processors of supercomputers.

简介：每个人都因为通信（电视，广播，互联网，无线和移动）和消费产品而熟悉电子产品。但是，这样的电子设备仅限于低功率范围。电力电子涉及巨型电力公用事业水平。例如，出于安全原因，Hydro-Quebec通过DC线路连接到美国新不伦瑞克省（在不久的将来与安大略省水电）连接。从AC转换为DC再到AC的设备基于电力电子技术。所有可再生能源技术（风能，光伏，太阳能等）都需要从频率更换（DC到60 Hz AC）或可变频率AC到60 Hz AC的类似设备。 经过数十年的主题研究后，“力量向高功率电子设备”以高压直流（HVDC）站的形式改善电力电子转换器，以及灵活的交流传输系统（FACTS）控制器，下一阶段的阶段是集成可再生能源的频率更换器，以提高电网的整体动态性能。令人兴奋的前景是：当可再生能源达到30％的渗透率时，功率可控制的功率（来自频率换频器）也将变为30％。 目的：除了继续改善HVDC和FACTS设备外，额外的挑战是利用30％的电力控制控制和改善大型互连电力系统的阻尼，其区域间振荡在过去导致停电。 科学方法： 除了电力电子技术外，研究方法还将扩展到小信号稳定性分析，本本函数概念的应用以及通过超级计算机的并行处理器计算本征函数的计算。
