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：每个人都熟悉电子产品，因为通信（电视，广播，互联网，无线和移动的）和消费产品。但这种电子设备仅限于低功率范围。电力电子处理电力公用事业的兆瓦级。例如，出于安全考虑，魁北克水电公司通过直流线路连接到美国的新玩法（以及不久的将来的安大略水电公司）。用于从AC转换到DC和返回到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）都需要类似的变频设备（DC到60 Hz AC，或变频AC到60 Hz AC）。 经过几十年的研究，在主题下，“强制换向大功率电子”，以改善高压直流（HVDC）站和灵活交流输电系统（FACTS）控制器形式的电力电子转换器，下一阶段包括集成可再生能源的变频器，以改善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，电网中的电力电子可控功率（来自变频器）也变为30%。 目的：除了继续改进HVDC和FACTS设备外，另一个挑战是使用30%的电力电子控制来稳定和改善大型互联电力系统的阻尼，这些系统的区域间振荡在过去曾导致停电。 科学方法： 除了电力电子技术，研究方法将扩展到小干扰稳定性分析，应用本征函数的概念和计算本征函数的并行处理器的超级计算机。
