Novel Method for Resiliency Evaluation of Smart Energy Systems

该项目的目标是建立一个联合状态分类模型，以便能够评估相互依存的多模式能源系统的（安全关键）功能。它将允许识别和分析系统的多个（多模式）领域（即电力，ICT，热力，天然气）的中断和故障（级联）。在这个项目中，申请人将调查这一领域的第一电力系统与互连的气体和热系统，和第二ICT系统，包括监督控制和数据采集和相关的通信。 该项目的第一步是分析停电对电力和信通技术系统的相互依赖性。在第二步中，经典的系统状态分类在电力系统（正常/N-1，警报，紧急情况下，停电）将详细考虑互连和相互依存关系，以其他多模式的能源系统。一次设备的停电和故障是这里状态变化的驱动因素。与多模式能源系统的互连将被视为中断，并将其结构化。特别是共模故障必须进行调查。沿着这些路线，系统状态分类将考虑到电力系统的监督，控制和保护功能的ICT系统。这一观点侧重于包括控制中心在内的二次设备，但也侧重于未来低于传输水平的较低电压水平的ICT。下一步将扩展的电力系统状态描述和ICT状态描述结合成一个集成的系统状态模型。一个正式的描述，这个模型和结构的国家和它们之间的过渡标准将开发。恢复路径的标准将沿着这一框架加以规定。 在最后一步中，将对不同状态及其发生的可能性进行风险分析。通过这种分析规划，明确了依赖信通技术的多模式能源系统的运营规划和运营标准。

The objective of this project is the modelling of a joint state classification that enables an assessment of interdependent multi-modal energy systems in terms of its (security-critical) functionalities. It will allow the identification and analysis of outages as well as failures (cascades) across multiple (multi-modal) domains of a system - i.e. electric, ICT, heat, gas. In this project the applicants will investigate this for the domains of first electric power systems with interconnections to gas and heat systems, and second ICT-systems including supervisory control and data acquisition and related communication. The first step of the project is to analyse blackouts regarding their interdependency of power and ICT-system. In a second step, classic system state classification in power systems (normal/N-1, alert, emergency, black out) will be detailed considering interconnections and interdependencies to other multi-modal energy systems. Outages and failures of primary equipment are the driving factors for state changes here. The interconnections to multi-modal energy systems will be considered and structured as outages. Especially common mode failures have to be investigated. Along these lines, system state classification will be done for the ICT-system considering the supervision, control and protection functions of power systems. This view focuses on the secondary equipment including control centres, but as well the future ICT on lower voltage levels below the transmission level. The next step combines both the extended power system state description and the ICT-state description into a integrated system state model. A formalized description of this model and the structure of the states and the criteria for the transition between them will be developed. Criteria for restoration paths will be specified along this framework. In the last step a risk analysis for the different states and the likelihood of their occurrence will be done. With such analysis planning, operation planning and operation criteria for ICT-reliant multi-modal energy systems are specified.
