Flexible Multi-Energy Infrastructure: New Approaches to Planning and Operating Active Distribution Systems During the Energy Transition

The article proposes a comprehensive approach to creating flexible multi-energy infrastructure, with the goal of improving the reliability, efficiency, and environmental friendliness of energy supplies to regions.

The methodology is based on the transition from separate energy production to cogeneration through the transformation of boiler houses into mini-CHPPs. To solve the problem of mismatched thermal and electrical load profiles, which limit the efficiency of cogeneration, we propose the introduction of flexible resources. Using developed models and methods, we performed simulation modeling and a comparative analysis of seven different energy system configurations on the example of the Linevo settlement, Russia. Power-to-heat technologies (electric boilers, heat pumps), and thermal energy storage system were analyzed as flexible resources. A quantitative assessment of efficiency indicators was conducted, which proved that the integration of flexible resources can significantly increase the utilization factor of cogeneration plants and ensure high investment attractiveness for projects with a payback period of up to 3-5 years. The transition to distributed energy sources as part of a multienergy infrastructure can help ensure the sustainable development of regions.
