Alberta's Interconnected Electrical System is undergoing a period of substantial change. The AlbertaGovernment has indicated that it plans to retire coal generation in Alberta by 2030, with 50%-75% of the coalcapacity being replaced with renewable sources; coal-based generation currently accounts for approximately40% of generating capacity and over half of all electrical energy production. As this change to generation fleetoccurs, Alberta is also expected to experience a rapid growth in population and industrial sector energydemand, requiring expansion of the overall capacity of the Alberta Interconnected Electrical System (AIES).The Climate Leadership Report envisages a system with 30% of generating capacity from renewable sourceswithin 14 years, with the remainder of capacity likely provided by gas-fired generation. The expected increasein growth and substantial change to generating sources present challenges to the design of a suitabletransmission system. These challenges are compounded by policy and regulations, which require that allin-merit generation must be accepted without constraint, a lengthy regulatory approval process for newtransmission, and the high cost to build or upgrade lines. For these reasons, the independent system operator(AESO) and transmission facility owners (TFO's) in Alberta are interested in approaches that maximize theutilization of transmission systems such that Alberta has a cost-effective, safe and reliable electrical supply.One approach to maximize transmission utilization is to dynamically operate systems to the safe limit of theexisting environmental conditions at the time, known as dynamic line rating (DLR). The project brings togethersenior Professors in Electrical, Computer and Mechanical Engineering to investigate how best to predict theenvironmental conditions across multiple spans of a transmission line, and how to use those environmentalconditions to predict the real-time ampacity of the transmission line. The project will work develop practicalsolutions, demonstrating the value of DLR to the system.

艾伯塔省的相互联系的电气系统正在经历一段重大变化的时期。艾伯特郡（Albertagovernment）表示，它计划到2030年在艾伯塔省退休煤炭发电，其中50％-75％的煤炭能力被可再生能源取代；目前，基于煤炭的发电量约占生成能力的40％，超过一半的电能生产。随着这一代舰队成员的这种变化，艾伯塔省还有望在人口和工业部门的能源数量中迅速增长，需要扩大艾伯塔省相互联系的电气系统（AIES）的整体能力。气候领导报告设想了一个系统的30％的系统，该系统具有30％的能力，即可再生能源14年的能力，其能力可能由剩余的能力提供，这可能是由生成生产的生成生成的。预期的增长和产生来源的实质性变化给适应性逆转录系统的设计带来了挑战。这些挑战是由政策和法规更加复杂的，这些法规要求必须接受Allin-Merit生成的情况，而无需限制，这是漫长的监管批准过程，用于新交易，以及建立或升级线路的高成本。由于这些原因，艾伯塔省的独立系统操作员（AESO）和传输设施所有者（TFO）对最大化传输系统的利用化的方法感兴趣，例如艾伯塔省具有一种成本效益，安全和可靠的电气供应。一种使传输利用最大化的方法是在动态的环境中最大程度地限制了动态的限制，以动态地限制了该线路的限制。该项目为电气，计算机和机械工程学带来了Togethersenior教授，以研究如何最好地预测传输线多个跨度的环境条件，以及如何使用这些环境条件来预测传输线的实时安培。该项目将开发实用施加，以证明DLR对系统的价值。
