Description of the Technology

 The modelling concepts are based on the energy hub approach - a framework where the production, conversion, storage and consumption of different energy carriers are done. It allows optimizing the energy system as the demand can be covered by different energy carriers to reach the lowest operating costs and higher reliability. The mathematical model of smart energy systems allows the identification of different technological solutions and operational conditions which need to be introduced for further development. The research methodology merges techno-economic analyses of possible heat production alternatives by using the EnergyPro optimisation model and life-cycle analyses.


Technical, economic and environmental assessment of integration options for multi-source heat supply is applicable to analyse optimal operating conditions and for the long-term planning of the development of energy systems, to define specific goals and tasks in heat supply companies in order to ensure the sustainable development of the energy sector.


The use of different heat sources to cover the demand for heat energy allows to increase the resistance of the heat supply system to changing external conditions, such as resource price increases or limited availability. Detailed arrangement of various available heat sources, including the use of heat storage systems and heat pumps, allows for more efficient use of available primary resources, lower operating costs and a reduction in the system's overall impact on the environment
