Ensuring secure and reliable operation of complex energy systems represents one of the most essential tasks for the well-functioning of modern industrial societies. The unprecedented pace at which the operating environments have changed during the last decade highlights the need for fundamental reconsideration of adopted practices in almost all parts of the industry. In this context, one of the most critical aspects represents the way how the increased levels of uncertainty related to large-scale integration of intermittent renewable energy sources would affect the definition, evaluation, and provision of system security in highly integrated structures near real time. The existing approaches for modeling, optimization, and control of electrical power systems mainly consist in solutions relying on assumptions that are increasingly questioned by the industry itself. For example, profound changes develop through the dramatic rise of renewable power generation and the advances in communication technology. In order to account for the expected technical challenges and also to respond to changing regulatory paradigms, the present project aims at the creation of a dedicated set of novel system-theoretic computational methods towards distributed security assessment and enhancement of power systems. Taking into account predictions regarding the future availability of fast communication and in addition relying on a specialized descriptor format managing the set of differential- algebraic equations, the proposed methods form a scalable and adaptive framework called DistDSA. The latter is to be suitable for deployment in vertically and horizontally integrated heterogeneous power systems and their operation near real time. Thanks to a computational stage of structure-preserving model order reduction, DistDSA for the first time optimizes short-term electromechanical system dynamics online and in a distributed way in their pure and approximated forms. The methods are designed to reflect the call for a multilateral provision of system security in electrical power systems of the next generation.

确保复杂能源系统的安全可靠运行是现代工业社会运转良好的最重要任务之一。在过去十年中，作业环境以前所未有的速度发生了变化，这突显出需要从根本上重新考虑油气行业几乎所有部门所采用的做法。在这种情况下，最关键的方面之一是，间歇性可再生能源大规模整合所带来的不确定性水平的增加，将如何影响高度集成结构中近实时系统安全的定义、评估和提供。现有的电力系统建模、优化和控制方法主要是基于假设的解决方案，而这些假设越来越受到行业本身的质疑。例如，可再生能源发电的急剧增长和通信技术的进步带来了深刻的变化。为了应对预期的技术挑战并响应不断变化的监管范式，本项目旨在创建一套专门的新型系统理论计算方法，用于分布式安全评估和增强电力系统。考虑到对未来快速通信可用性的预测，以及依赖于管理微分代数方程集的专门描述符格式，所提出的方法形成了一个可扩展和自适应的框架，称为DistDSA。后者适合于部署在垂直和水平集成的异构电力系统中，并在接近实时的情况下运行。由于结构保持模型降阶的计算阶段，DistDSA首次以纯和近似形式在线和分布式方式优化了短期机电系统动力学。这些方法旨在反映对下一代电力系统中系统安全的多边提供的呼吁。
