Operation of power systems with sustainable energy resources in competitive electricity markets

过去十年，随着世界各地电力市场的放松管制，电力系统的运行发生了重大转变。因此，尽管在以前的垂直一体化、单一所有者结构中，电网可靠性是最重要的，但目前的运行模式已转向经济问题压倒其他系统运行问题的环境；2003年8月发生在北美东北部的停电事件清楚地说明了这一重大焦点转移的影响。另一方面，在大多数竞争激烈的市场上，系统安全是通过相当保守地定义的输电系统拥堵限制来计算的，因此在某些情况下导致市场效率低下，导致不必要的价格飙升，甚至导致系统运行不安全。最后，人们对增加对环境友好的能源的使用，如风能、太阳能和氢能的使用，以及使电能消耗对价格和环境条件的反应更加敏感，引起了极大的兴趣。考虑到上述问题，拟议的研究首先旨在继续我们的开创性工作，由之前的NSERC发现拨款支持，更好地表示市场和系统操作程序和算法内的系统安全限制；这项工作将需要开发新的和实用的优化方法，这些方法是拟议的市场清算和调度算法的核心。其次，我们的工作将旨在开发在电力和天然气市场以及氢经济的背景下，市场参与者的优化运行的技术和算法。最后，第三个主要研究目标将是研究如何在上述技术中适当地考虑环境友好型能源的影响，特别是风能和太阳能，同时考虑将氢气作为替代能源载体。他表示，申请的资金将主要用于支持博士/硕士学生，以增加我们培养的大量HQP，这些人在加拿大电力行业非常需要。

The operation of power systems has undergone a major shift over the past decade with the deregulation of electricity markets around the world.  Thus, while in the previous vertical-integrated, single-owner structure, grid reliability was paramount, the current operating paradigm has shifted towards an environment where economic issues prevail over other system operating concerns; the blackout of August 2003 in the North East of North America clearly illustrates the effects of this significant shift in focus.  On the other hand, system security is accounted on most competitive markets by means of transmission system congestion limits defined rather conservatively, thus leading in some cases to market inefficiencies that result on unnecessary price spikes and even insecure system operation.  Finally, there is significant interest on increasing the use of environmentally friendly energy sources, such as wind, solar and hydrogen, as well as making electric energy consumption more responsive to price and environmental conditions.    With the aforementioned issues in mind, the proposed research aims first at continuing our pioneering work, supported by a previous NSERC Discovery Grant, on a better representation of system security limits within market and system operating procedures and algorithms; this work will require the development of novel and practical optimization methodologies that are at the heart of the proposed market clearing and dispatch algorithms.  Second, our work will aim at developing techniques and algorithms for optimal operation of market participants, in the context of electricity and gas markets and a hydrogen economy.  Finally, the third major research objective will be to study how to properly account for the effect of environmentally friendly energy sources in the abovementioned techniques, in particular wind and solar while considering hydrogen as an alternative energy carrier.      The requested funds will be used to mainly support PhD/MSc students to add to the significant number of HQP we have trained, and who are badly needed in the electricity industry in Canada.
