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.

该项目的目标是建立联合状态分类的模型，以评估相互依赖的多模式能源系统的(安全关键)功能。它将允许识别和分析一个系统的多个(多模式)领域--即电力、信息和通信技术、热力、燃气--的停电和故障(级联)。在本项目中，申请者将研究第一电力系统与燃气和供热系统互连的领域，以及第二信息和通信技术系统的领域，包括监督控制和数据采集及相关通信。该项目的第一步是分析停电与电力和信息和通信技术系统的相互依存关系。在第二步中，将详细介绍电力系统中的经典系统状态分类(正常/N-1、警报、紧急、停电)，考虑到与其他多模式能源系统的相互联系和相互依赖。一次设备的停机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停电并被构建为停电。尤其是必须调查共模故障。沿着这些思路，考虑电力系统的监测、控制和保护功能，对ICT系统进行系统状态分类。这一观点侧重于二次设备，包括控制中心，以及未来信息和通信技术对输电水平以下较低电压水平的影响。下一步，将扩展的电力系统状态描述和ICT状态描述结合到一个集成的系统状态模型中。将对这一模型和状态的结构以及它们之间的转换标准进行形式化描述。将沿着该框架指定恢复路径的标准。在最后一步中，将对不同的州及其发生的可能性进行风险分析。通过这种分析规划，明确了信息和通信技术依赖型多式联运能源系统的运行规划和运行标准。
