Planning and operation of integrated energy systems with high penetration of renewables

作为使加拿大成为清洁能源开发领先者的综合计划的一部分，联邦政府正在加快其在2030年前逐步淘汰燃煤发电的计划。在加拿大，燃煤发电厂产生了相当大一部分电力，因此，消除燃煤发电厂对电力公用事业的可靠规划和运营构成了前所未有的挑战。电力公用事业公司的目标是增加风力发电等间歇性和可变可再生能源在其系统中的渗透率，这一事实进一步加剧了这种情况。为了解决上述问题，最近提出了综合能源系统，该系统考虑了不同类型的能源需求、电网和燃气网络之间的相互作用。综合能源系统利用不同能源网络之间的相互依赖关系，以确保这些网络的可靠运行。在这方面，该项目的目标是在可再生能源普及率较高的情况下，为综合能源系统开发全面的规划和运行方法，该项目的新研究成果将包括系统部件的准确模型，如能量转换器，以及用于综合能源系统规划、运行和可靠性测量的新方法和模拟工具。研究结果将为综合能源系统的设计提供重要的技术投入和参考，使电力和能源公用事业公司能够在未来进行更可行的投资。这些工作将帮助加拿大实现安全、可靠和可持续的电力供应，同时不断适应不断增加的可再生能源发电。这一研究项目将帮助加拿大培养高素质的人才，特别是拥有先进电力和能源系统相关技能的电力工程专业毕业生。

As part of a comprehensive plan to make Canada a front-runner in clean energy exploitation, the FederalGovernment is accelerating its plan to phase out coal-powered electricity generation by 2030. Coal-fired powerplants produce a considerable portion of the electricity in Canada, and hence eliminating them posesunprecedented challenges to reliable planning and operation for electric utilities. The situation is furtheraggravated by the fact that electric utilities are aiming to increase the penetration of intermittent and variablerenewable energy sources such as wind power in their systems. To address the aforementioned issues,integrated energy systems, which consider the interactions among different types of energy demand, theelectricity network, and the gas network, have been recently proposed. Integrated energy systems exploit theinterdependency of different energy networks so as to ensure the reliable operation of those networks. In thisregard, this project aims to develop comprehensive planning and operation approaches for integrated energysystems in the presence of high renewable energy penetration, which is still in its infancy.Novel research outcomes of this project will include accurate models of system components, such as energyconverters, and new approaches and simulation tools for planning, operation, and reliability measures ofintegrated energy systems. The research results will provide significant technological inputs and referencesrelated to the design of integrated energy systems that will allow power and energy utilities to make moreviable investments in the future. These works will help Canada to achieve a safe, reliable, and sustainablepower supply while continuously adapting to increasing power generation from renewable energy sources. Thisresearch project will help Canada train highly qualified personnel, specifically power engineering graduateswho will be well-equipped with skill sets relevant to advanced power and energy systems.
