Integrated Energy System Analysis and Planning

电力系统在运行和规划方面正处于一场重大革命的边缘。在过去，这些系统和能源（如电、热、汽油、天然气等）通常没有被有意地综合规划或运行。然而，不同能源系统和资源之间的相互影响正变得越来越重要。例如，以天然气为动力的电力系统，不仅在燃料来源方面存在相互依存关系，而且更加强调能源效率和温室气体，增加了它们的利用，以及未来热电联产的增长。***从长远来看，综合能源系统规划需要考虑可再生能源（如太阳能、风能）、能源储存和需求响应（即客户用电量的变化）的大幅增长。这些技术正在从根本上改变能源系统的规划和运行方式。传统的天然气发电机组可以很好地应对与可再生资源发电相关的变化，而当发电量更恒定时，热电联产机组运行得更好。在发电端实施的重大变化与增加的负荷（需求）参与和响应相匹配。***拟议的研究计划将侧重于a)具有大容量或潜力的热电联产系统；B)可再生能源，如风能和太阳能发电；c)能量储存。能源系统相互依赖性的增加将使电力能源系统的规划和操作更加复杂，需要更多地使用专门技术和工具来处理多个目标，同时也考虑到不确定性和随机变量。我们研究的总体目标是为21世纪电力系统的系统规划者和操作员开发工具和技术。这项工作对加拿大在能源部门的竞争力和为子孙后代保持“灯亮”至关重要。**

Electrical energy systems are on the edge of a significant revolution with respect to their operation and planning. In the past, these systems and energy resources (e.g., electrical, heat, gasoline, natural gas, etc.) generally have not been planned or operated in an intentionally integrated manner. However, the impacts of different energy systems and resources on each other are becoming increasingly important. For example, with electrical systems powered by natural gas, not only is there interdependency with respect to fuel source, but a greater emphasis on energy efficiency and greenhouse gases has increased their utilization, and the future growth of combined heat and power generation. ***In the long term, integrated energy system planning will need to consider sizeable increases in renewable energy sources (e.g., solar, wind), energy storage, and demand response (i.e., changes in electric usage by customers). These technologies are fundamentally transforming how energy systems are planned and operated. While traditional, natural gas-based electrical generation units can respond well to variability associated with renewable resource generation, combined heat and power units operate better when generation output is more constant. The significant changes being implemented on the generation side are matched by increased load (demand) participation and responsiveness. ***The proposed program of research will focus on a) systems with large capacity or potential for combined heat and power; b) renewable energy such as wind- and solar-based generation; and c) energy storage. The increased interdependency in energy systems will make the planning and operations of electrical energy systems more complex, requiring increased use of specialized techniques and tools to handle multiple objectives while also accounting for uncertainty and random variables. The overall goal of our research is to develop tools and techniques for system planners and operators of 21st century power systems. This work will be essential to Canada's competitiveness in the energy sector and to keeping the “lights on” for future generations. **
