Societal pressure to reduce the environmental impacts of electricity production has led to a dramatic increase in the amount of variable generation on Canada's power grids, particularly wind generation. For example, Ontario's Renewable Energy Standard Offer Program and Feed-In Tariff have led to an installed wind generation capacity of over 3000 MW within the province. These changes have the potential to negatively impact the reliability of grid operations, particularly due to their detrimental impact on power grid operators' situational awareness (i.e., their awareness of the current state of the system and of future problems that might arise). The importance of situational awareness is hard to overstate, given the catastrophic consequences that may result (e.g., lack of situational awareness was a root cause of the August 2003 blackout in the U.S. and Canada, which cost an estimated $6 billion and contributed to at least 11 deaths). Enhancing power grid situational awareness, with particular consideration of the challenges associated with variable generation, is the main goal of the proposed research program. Two specific short term goals that will be addressed are: (1) improve operators' understanding of the impact that forecast uncertainties have on future grid conditions (e.g., system voltages and branch loading) and (2) improve grid device models to enable accurate assessment of transient stability. To achieve these goals, we will build upon our expertise in several key areas, including: evaluating the impact of generation uncertainty on network reliability, model identification, and grid visualization.**

减少电力生产对环境影响的社会压力导致加拿大电网的可变发电量急剧增加，特别是风力发电。例如，安大略省的可再生能源标准报价计划和上网电价导致该省风力发电装机容量超过3000兆瓦。这些变化有可能对电网运行的可靠性产生负面影响，特别是因为它们对电网运营商的形势意识(即他们对系统当前状态和未来可能出现的问题的认识)产生了不利影响。考虑到可能导致的灾难性后果(例如，缺乏情景意识是2003年8月美国和加拿大停电的根本原因，估计造成60亿美元的损失，并导致至少11人死亡)，情景感知的重要性怎么强调都不为过。增强电网态势感知，特别是考虑到与变量发电相关的挑战，是拟议研究计划的主要目标。将解决的两个具体短期目标是：(1)提高运营商对预测不确定性对未来电网状况(例如系统电压和分支负载)的影响的理解；(2)改进电网设备模型，以实现对暂态稳定性的准确评估。为了实现这些目标，我们将在几个关键领域建立我们的专业知识，包括：评估发电不确定性对网络可靠性、模型识别和电网可视化的影响。**
