Wind energy, due to its free availability and clean and renewable character, ranks as the most promising energy resource that could play a key role in solving the world energy crisis. According to Canada Wind Energy Association (CWEA), Canada's wind energy industry has already broken its annual growth record in 2009 with 950 MW of new wind energy capacity, with a total capacity of 3499 MW till September 2010. The CWEA in its 'WindVision 2025' document sets a goal of producing 20% or more of the country's electricity from wind power by 2025. Due to significantly higher and more constant wind speeds, reduced planning restrictions, and the shortage of suitable sites for wind farms on the land, off-shore wind farms are becoming very attractive. Europe has held the lead in off-shore wind, having installed more than 830 turbines with grid connections to nine European countries. Canada has also started investing in off-shore wind farms with many projects in line. To transit such bulk power over great distances, in sea, creates challenges for both system operators and wind farm developers, apart from inherent wind's intermittent nature. From the off-shore collection point to on-shore grid, VSC-HVDC technology has many advantages over other transmission links such as, HVAC or HVDC with thyristor-based line-commutated converters (LCC). It is becoming more and more important to develop advanced control techniques so that the integration of off-shore wind farms with the on-shore grid is more reliable, efficient and free from power quality problems. Therefore, the objectives of the proposed research work is 1) to conceive, analyze/evaluate, fabricate/test proper converter/inverter topology and its control for VSC HVDC system (simulated on a real-time digital simulator - RTDS), for various types of off-shore wind farms. 2) to simulate an on-shore power system network on a RTDS. 3) to develop proper control techniques to integrate off-shore wind farms (of objective 1) with an on-shore power system network (of objective 2). 4) Performance evaluations of integrated off-shore wind farms and on-shore power network for various operating conditions.

风能，由于其免费提供和清洁和可再生的特点， 有前途的能源，可以在解决世界能源危机中发挥关键作用。根据加拿大风能协会（CWEA）的数据，加拿大的风能行业已经打破了2009年的年度增长记录，新增风能容量为950兆瓦，到2010年9月总容量为3499兆瓦。CWEA在其“WindVision 2025”文件中设定了一个目标，即到2025年，该国20%或更多的电力来自风力发电。由于风速明显更高和更恒定，减少了规划限制，以及陆地上风力发电场合适场地的短缺，离岸风力发电场正变得非常有吸引力。 欧洲在海上风力发电方面处于领先地位，安装了830多台涡轮机，与9个欧洲国家联网。加拿大也开始投资离岸风电场，许多项目正在进行中。除了固有的风的间歇性之外，在海上长距离传输这种大容量电力给系统运营商和风电场开发商带来了挑战。从离岸收集点到岸上电网，VSC-HVDC技术具有许多优于其他传输链路的优点，例如具有基于晶闸管的线路换向换流器（LCC）的HVAC或HVDC。开发先进的控制技术，使海上风电场与陆上电网的集成更加可靠，高效，并且没有电能质量问题变得越来越重要。因此，所提出的研究工作的目标是：1）构思、分析/评估、制造/测试适当的换流器/逆变器拓扑结构及其控制，用于各种类型的海上风电场的VSC HVDC系统（在实时数字仿真器- RTDS上仿真）。2)在RTDS上模拟陆上电力系统网络。3)开发适当的控制技术，将海上风电场（目标1）与陆上电力系统网络（目标2）相结合。4)各种运行条件下海上风电场和陆上电网的综合性能评估。
