SBIR Phase II: Cloud-Based Electric Power Grid Simulation Software With Equivalent Circuit Methods

小型企业创新研究(SBIR)第二阶段项目的更广泛影响将来自于实现更安全、更可靠和更具弹性的电力系统的能力。可靠、高效的电网是国家经济的基石。随着分布式能源(DER)的迅速采用，从传统发电厂向公用事业规模的风电场和太阳能发电场的过渡，以及对大宗电力系统的网络和/或物理攻击的威胁，确保电网的可靠性和弹性变得越来越具有挑战性。该项目正在开发的软件将帮助电网规划工程师和运营商应对这些现代挑战。来自公用事业行业组织的工程师将首次能够在安全、可扩展、基于云的软件平台上协作规划电网，该平台提供全面评估可再生能源和DER影响所需的功能。该软件行业领先的模拟稳健性将允许用户分析极端意外情况、级联事件和薄弱电网情景，以制定保护电网安全的预防和纠正措施。该软件旨在支持美国每年超过500亿美元的电力基础设施投资和每年超过4000亿美元的电力市场交易。这个小型企业创新研究第二阶段项目将开发用于电力传输和分配(T&A；D)规划的软件。技术任务是：1)通过自动缩放和排队服务使云架构响应需求；2)最大限度地减少数据存储需求；3)管理数据处理，以减少数据集的重载；4)为行业标准的三相不平衡配电系统模型实施文件解析器；5)实施常见配电系统组件的模型；以及6)扩展云平台以支持集成T&A；D分析。这些优化组件的集成将导致改进的系统设计用于大规模使用。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact of this Small Business Innovation Research (SBIR) Phase II project will result from the ability to enable a safer, more reliable, and more resilient electric power system. A reliable and efficient grid is the cornerstone of the nation’s economy. With the rapid adoption of distributed energy resources (DERs), a transition from conventional generation plants to utility-scale wind and solar farms, and the threat of cyber- and/or physical attacks on the bulk electric system, ensuring the reliability and resilience of the grid has become ever more challenging. The software being developed in this project will help grid planning engineers and operators cope with these modern challenges. For the first time, engineers from organizations across the utility industry will be able to collaboratively plan the grid on a secure, scalable, cloud-based software platform that provides the capabilities needed to fully assess the impact of renewables and DERs. The software’s industry-leading simulation robustness will allow users to analyze extreme contingencies, cascading events, and weak grid scenarios to develop preventive and corrective actions that secure the grid. The software is designed to support an annual $50B+ in US power infrastructure investment and an annual $400B+ in power market transactions.This Small Business Innovation Research Phase II project will develop software for electric power transmission and distribution (T&D) planning. Technical tasks are to: 1) Make cloud architecture responsive to demand with autoscaling and queueing services; 2) Architect results generation for minimized data storage requirements; 3) Manage data handling for reduced re-loading of datasets; 4) Implement a file parser for industry-standard three-phase unbalanced distribution system models; 5) Implement models of common distribution system components; and 6) Extend the cloud platform to support integrated T&D analysis. Integration of these optimized components will lead to an improved system engineered for usage at scale.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
