项目摘要
While extensive attention has been given to sustainability in the energy systems, including the subsystems of electricity, petroleum, and natural gas, an oft-overlooked aspect is the interdependence between energy and other infrastructure systems, such as water and transportation systems, and the potential adverse impacts to economics, reliability, and sustainability caused by such interdependence. For example, regulations in the water sector to preserve freshwater may restrict water usage in the power sector, likely causing reduced available generation capacities and hence jeopardizing the reliability of power systems. On the other hand, environmental policies only focused on the power sector, such as those encouraging retrofitting or installing carbon dioxide capture and sequestration capabilities to existing and new coal plants would further constrain the water system as coal plants with carbon sequestration are among the heaviest users of water. Thus, there is a clear need to better understand and manage the interdependence of critical infrastructure systems to promote sustainability across all systems, while not undermining economic and reliability considerations. This proposed work aims to address this need through the theory, modeling and computation of large-scale, interdependent complex systems by way of distributed, highly scalable computing. The results will be widely disseminated through publications and seminars. Further, the project team will leverage established institutional outreach programs to the general public, especially to high-school students and teachers, such as through the Engineering Projects In Community Service program and Purdue?s Energy Academy. The grand vision of this project is to promote sustainability across interdependent systems, as well as to achieve economic efficiency and to maintain reliability through decentralized yet coordinated management of individual systems by establishing a complete modeling, analytical, and computational framework based upon the general class of augmented Lagrangian methods originating from convex optimization. While the augmented Lagrangian method is not a new algorithm, the current implementation of such algorithms has not taken advantage of its distributed feature, which would be particularly suitable to deal with large-scale, interlinked systems. One of the major goals of this work is to establish the theoretical foundations of distributed Lagrangian methods and to implement the algorithms on supercomputer clusters to demonstrate the benefits of distributed computing. This research aims to pave the way for cloud computing such that the algorithms can be used by decision-makers even without access to supercomputers. Another contribution is that the augmented Lagrangian method algorithms will be extended to incorporate stochastic data, both in terms of theoretical issues such as algorithm convergence as well as practical implementation. The computational methods will be tested and validated through real-world models of interdependent power and water systems.
虽然能源系统(包括电力、石油和天然气子系统)的可持续性受到广泛关注,但一个经常被忽视的方面是能源与其他基础设施系统(例如水和运输系统)之间的相互依赖关系,以及这种相互依赖关系对经济性、可靠性和可持续性造成的潜在不利影响。例如,水务部门保护淡水的法规可能会限制电力部门的用水,可能导致可用发电能力减少,从而危及电力系统的可靠性。另一方面,环境政策仅关注电力部门,例如鼓励对现有和新建燃煤电厂改造或安装二氧化碳捕获和封存能力的政策,将进一步限制水系统,因为碳封存的燃煤电厂是用水量最大的电厂之一。因此,显然需要更好地理解和管理关键基础设施系统的相互依赖性,以促进所有系统的可持续性,同时不损害经济和可靠性考虑。这项工作旨在通过分布式、高度可扩展的计算,通过大规模、相互依赖的复杂系统的理论、建模和计算来满足这一需求。研究结果将通过出版物和研讨会广泛传播。此外,项目团队将利用现有的机构外展计划向公众,特别是高中生和教师,例如通过社区服务工程项目和普渡大学能源学院。该项目的宏伟愿景是促进相互依存系统的可持续性,并通过基于凸优化的一般增强拉格朗日方法建立完整的建模、分析和计算框架,通过对各个系统进行分散而协调的管理来实现经济效率并保持可靠性。虽然增广拉格朗日方法并不是一种新算法,但目前此类算法的实现并没有利用其分布式特性,而分布式特性特别适合处理大规模、互连的系统。这项工作的主要目标之一是建立分布式拉格朗日方法的理论基础,并在超级计算机集群上实现算法以展示分布式计算的好处。这项研究旨在为云计算铺平道路,使决策者即使无法访问超级计算机也可以使用这些算法。另一个贡献是增强拉格朗日法算法将扩展到包含随机数据,无论是在算法收敛等理论问题还是实际实现方面。计算方法将通过相互依赖的电力和水系统的真实模型进行测试和验证。
