Exergoeconomic Optimization of Borehole Thermal Energy Storage in District Heating and Cooling Grids

Abstract

Detailed techno-economic assessment of Borehole Thermal Energy Storage (BTES) systems in District Heating and Cooling (DHC) grids is required for successful practical implementation of such systems. As there are many parameters that must be considered, a method has to be chosen so that all parameters affecting the combined system’s performance can be assessed comprehensively and the ones with a higher impact can be identified and regulated. By utilizing the exergoeconomic analysis method, the thermoeconomic performance of different components and their interactions can be investigated. The main aim of this work is to assess the efficient integration of BTES systems into DHC grids by utilizing an exergoeconomic optimization method.
