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.

艾伯塔省的互联电力系统正在经历一段重大变革时期。艾伯塔省政府表示，计划到2030年停止艾伯塔省的煤炭发电，50%-75%的煤炭产能被可再生能源取代；目前，煤炭发电约占发电量的 40%，占全部电能产量的一半以上。随着发电量的变化，艾伯塔省预计人口和工业部门能源需求也将快速增长，需要扩大艾伯塔省互联电力系统 (AIES) 的整体容量。气候领导力报告设想该系统将拥有 30% 的发电量14年内利用可再生能源发电，其余发电量可能由燃气发电提供。预期的增长和发电来源的重大变化对合适的传输系统的设计提出了挑战。这些挑战因政策和法规而变得更加复杂，这些政策和法规要求必须不受限制地接受优质发电、新输电的监管审批流程漫长，以及建设或升级线路的高昂成本。出于这些原因，艾伯塔省的独立系统运营商 (AESO) 和输电设施所有者 (TFO) 对最大限度地利用输电系统的方法感兴趣，以便艾伯塔省拥有具有成本效益、安全和可靠的电力供应。最大化输电的一种方法利用是动态操作系统到当时现有环境条件的安全极限，称为动态线路额定值（DLR）。该项目汇集了电气、计算机和机械工程领域的高级教授，研究如何最好地预测输电线路多个跨度的环境条件，以及如何利用这些环境条件来预测输电线路的实时载流量。该项目将致力于开发实用的解决方案，展示 DLR 对系统的价值。
