Dynamic Line Rating Solutions for Alberta

阿尔伯塔的互联电力系统正在经历一个重大变化的时期。阿尔伯塔 政府已经表示，计划到2030年在阿尔伯塔淘汰煤炭发电，其中50%-75%的煤炭 容量被可再生能源取代;煤基发电目前约占 40%的发电能力和超过一半的电力生产。随着这一变化， 发生，阿尔伯塔预计也将经历人口和工业部门能源的快速增长 需求，需要扩大阿尔伯塔互联电力系统（AIES）的总容量。 气候领导力报告设想了一个30%的发电能力来自可再生能源的系统 在14年内，剩余的容量可能由燃气发电提供。预期增强 在增长和实质性的变化，以产生源提出了挑战，设计一个合适的 传输系统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所有人都必须 必须无限制地接受有价值的发电，这是一个漫长的监管审批过程， 传输，以及建造或升级线路的高成本。基于这些原因，独立系统运营商 阿尔伯塔的AESO和输电设施所有者（TFO）对最大化 利用输电系统，使阿尔伯塔省拥有成本效益高、安全可靠的电力供应。 最大化传输利用率的一种方法是动态地操作系统到传输的安全极限。 在当时的环境条件下，称为动态线路额定值（DLR）。该项目汇集 高级教授在电气，计算机和机械工程，以研究如何最好地预测 跨传输线的多个跨度的环境条件，以及如何使用这些环境条件 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。

Alberta's Interconnected Electrical System is undergoing a period of substantial change. The Alberta Government has indicated that it plans to retire coal generation in Alberta by 2030, with 50%-75% of the coal capacity being replaced with renewable sources; coal-based generation currently accounts for approximately 40% of generating capacity and over half of all electrical energy production. As this change to generation fleet occurs, Alberta is also expected to experience a rapid growth in population and industrial sector energy demand, 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 sources within 14 years, with the remainder of capacity likely provided by gas-fired generation. The expected increase in growth and substantial change to generating sources present challenges to the design of a suitable transmission system. These challenges are compounded by policy and regulations, which require that all in-merit generation must be accepted without constraint, a lengthy regulatory approval process for new transmission, 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 the utilization 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 the existing environmental conditions at the time, known as dynamic line rating (DLR). The project brings together senior Professors in Electrical, Computer and Mechanical Engineering to investigate how best to predict the environmental conditions across multiple spans of a transmission line, and how to use those environmental conditions to predict the real-time ampacity of the transmission line. The project will work develop practicalsolutions, demonstrating the value of DLR to the system.
