Resilience Metrics for District Heating Systems: A Comprehensive Framework
The project`s main output is the framework that aims to clarify which key performance indicators of the DH system should be used when assessing the resilience to climate-change-related, technological and financial disruptive events. The framework will be implemented in a web platform serving as an optimization tool for a comprehensive evaluation of resilience performances within the planning, design and operational phases of DH systems. The evaluation for DH system resilience will focus on energy-efficient and cost-effective heat generation under different climatic, economic and social conditions. The identification of different resilience criteria and the system resilience to maintain high heat generation performance in case of scenarios embedding different technological and potentially disruptive events will be analysed. Furthermore, innovative DH solutions will be evaluated within the research, such as the power-to-heat concept, network temperature lowering, and continuous heat and cold generation for particular case studies in order to identify benefits and barriers in terms of the system’s ability to maintain high performance under various conditions. The results will be a key output that can be used in policy planning, stimulating future research in the specific industrial sector at the local and international levels.
