The NSF Sustainable Energy pathways (SEP) Program, under the umbrella of the NSF Science, Engineering and Education for Sustainability (SEES) initiative, will support the research program of Prof. Dennice Gayme and co-workers at Johns Hopkins University, Prof. Aranya Chakrabortty and co-workers at North Carolina State University, and Prof. Judith cardell and co-workers at Smith College to develop a method to integrate heterogeneous energy resources to form sustainable power networks. The objective of this program is to examine how the control and design of large-scale and distributed energy resources can facilitate the grid-integration of large amounts of renewable energy. Wind energy is used as a representative, heterogeneous and variable renewable energy source to address the following three fundamental challenges: (I) the need to manage stability, (II) the need to cost effectively maintain reliable operation, and (III) the need to reflect stability and operational criteria in markets and policy. Models of the power grid, such as continuum representations (partial differential equations that directly support combined spatial and temporal analysis) and network power flows that include storage and demand-side management, will be developed and used to address stability, control, reliability, and performance/efficiency questions. As input for these continuum and power flow models, the project will utilize outputs from fluid dynamics ("Large-Eddy") simulations that model unsteady wind farm and atmospheric boundary layer interactions and have been validated using laboratory and field observations. Analysis using the grid level models will both inform and be shaped by the design of new regulatory and economic reforms that will enable renewable resource purveyors to participate in power markets. Connections between operational and market issues such as power flow regulation, grid operation and risk mitigation strategies using storage and demand-side management will be made by leveraging tools based on optimization, convex relaxations and optimal control theory, which are common to the economics and controls communities. This project will facilitate a more sustainable power system through its technical contributions, education, training and mentorship. Research topics will form the basis for student projects in new sustainable energy related curricula at all three participating institutions. Summer undergraduate research opportunities will provide students with skills for participating in sustainable energy research and future employment in related industries. This program will directly facilitate NSF's STEM related goals through JHU's participation in the NSF-funded Center for Integration of Research, Teaching, and Learning (CIRTL), the Science House partnership between NCSU and local K-12 teachers, and the involvement of the only all-women engineering program in the US (Smith College). At JHU this project will operate under the aegis of E2SHI, which promotes cross-disciplinary research, outreach, and education for critical environmental, energy and sustainability issues. E2SHI is committed to systems-level integrated research and outreach for sustainability.The tools to be developed will help facilitate the transformation of our current fossil fuel based power system to one that is safe, reliable and efficient without compromising energy security or exhausting resources needed for future generations. The project's results will be directly relevant to the electric power industry and its regulators as they are faced with the challenges of incorporating larger fractions of highly heterogeneous renewable resources, such as wind energy, into the grid. Specifically, the results will provide system operators with better representations of the impacts of renewables, and better control tools to mitigate those impacts; planners and investors with a framework for evaluating optimal resource allocation; and policy makers with a systematic means of investigating how new regulations and market rules can incent effective deployment of these tools and resources. Complementary educational programs and mentorship will develop researchers and practitioners with the skills required to create and advance this sustainable energy future.

在NSF科学，可持续性工程和教育（SEES）计划的统治下，NSF可持续能源道路（SEP）计划将支持Dennice Gayme教授的研究计划和Johns Hopkins University的Johns Hopkins大学，Aranya Chakrabortty教授及其北卡拉罗纳州立大学的合作者，并在Carolina Contell Coartell和Prof.形成可持续电力网络的异质能源。该计划的目的是研究大规模和分布式能源资源的控制和设计如何促进大量可再生能源的网格集成。风能被用作代表性，异质和可变可再生能源来应对以下三个基本挑战：（i）管理稳定的需求，（ii）成本上有效地维持可靠的操作，以及（iii）反映市场和政策中稳定性和运营标准的需求。 电源网格的模型，例如连续表示（直接支持合并空间和时间分析的部分微分方程）以及包括存储和需求端管理在内的网络功率流，并将用于解决稳定性，控制，可靠性，性能/效率问题。作为这些连续性和功率流模型的输入，该项目将利用来自流体动力学（“大码”）模拟的输出，这些模拟模拟了不稳定的风电场和大气边界层相互作用，并已使用实验室和现场观察进行了验证。使用网格级别模型的分析将通过设计新的监管和经济改革的设计为和塑造，这将使可再生资源供应商能够参与电力市场。运营和市场问题之间的联系，例如电力流量调节，网格操作以及使用存储和需求方管理的风险缓解策略，可以通过基于优化，凸出放松和最佳控制理论的工具来建立，这对于经济学和控制社区来说是共同的。该项目将通过其技术贡献，教育，培训和指导来促进更可持续的电力系统。研究主题将构成所有三个参与机构在新的可持续能源课程中的学生项目的基础。夏季的本科研究机会将为学生提供参与可持续能源研究和未来就业的技能。该计划将通过JHU参与NSF资助的研究，教学和学习融合中心（CIRTL），NCSU与本地K-12教师之间的科学院合作伙伴关系以及唯一在US（Smith College）中唯一的全Women Engineering计划的参与来直接促进NSF与STEM相关的目标。在JHU，该项目将在E2SHI的宙斯盾下运作，该项目促进了关键的环境，能源和可持续性问题的跨学科研究，外展和教育。 E2SHI致力于系统级的综合研究和可持续性。开发的工具将有助于促进我们当前基于化石燃料的电力系统的转型，即安全，可靠和有效的工具，而不受损害能源安全或耗尽后代所需的资源。该项目的结果将与电力行业及其监管机构直接相关，因为它们面临的挑战是将较大的高度异构可再生资源（例如风能）纳入网格。具体而言，结果将为系统操作员提供更好的可再生能源影响的表示，以及更好地控制这些影响的工具；计划者和投资者，具有评估最佳资源分配的框架；以及采用系统性手段的政策制定者，可以调查新的法规和市场规则如何有效部署这些工具和资源。互补的教育计划和指导将开发研究人员和从业人员，具有创造和推动这一可持续能源未来所需的技能。
