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

在过去的十年中，随着世界各地电力市场的放松管制，电力系统的运行经历了重大转变。 因此，虽然在以前的垂直一体化，单一业主的结构，电网的可靠性是最重要的，目前的运营模式已经转向一个环境中，经济问题占主导地位的其他系统的运营问题;停电2003年8月在北美东北部清楚地说明了这种重大转变的影响。 另一方面，在大多数竞争性市场上，系统安全性是通过相当保守地定义的传输系统拥塞限制来考虑的，因此在某些情况下导致市场效率低下，从而导致不必要的价格飙升甚至不安全的系统操作。 最后，人们对增加使用风能、太阳能和氢等环境友好型能源以及使电能消耗更好地适应价格和环境条件非常感兴趣。 考虑到上述问题，拟议的研究的目的首先是继续我们的开创性工作，由以前的NSERC发现补助金的支持，在市场和系统操作程序和算法内的系统安全限制的更好的表示;这项工作将需要开发新的和实用的优化方法，在拟议的市场清算和调度算法的核心。 第二，我们的工作将旨在开发技术和算法，在电力和天然气市场以及氢经济的背景下，实现市场参与者的最佳运作。 最后，第三个主要研究目标将是研究如何在考虑氢作为替代能源载体的同时，适当考虑上述技术中环境友好能源的影响，特别是风能和太阳能。 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，以及加拿大电力行业急需的HQP。

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.
