Abstract

The Solar assisted district heating system (SDHS) is a promising path to accelerate the sustainable movement toward clean energy production in order to solve the challenges of the energy crisis and climate change. However, in real conditions the SDHS is often suffering from a mismatch between the predict and actual performance. This mismatch promotes a high variation in quantifying the SDHS benefits at different urban community sizes. This article traces the techno-economic performance of SDHS through an optimization framework using dynamic TRNSYS for simulations and a genetic algorithm for optimization. The SDHS application is performed for a residential community of 10, 25 and 50 buildings located in Madrid to evaluate its techno-economic feasibility in covering the heating demand of these communities. The larger communities provided noticeable cost-benefits when aiming for high performance, where the cost objective is between 73.1:149.1 Euro/MWh for the community of 10 and it can be improved up to 27.5% and 41.6% for community sizes of 25 and 50 buildings, respectively. While in terms in the payback period, it can be reduced up to 29 years for the community size of 50 buildings. The solar fraction can achieve up 99% with a seasonal storage tank efficiency of 81% at the community size of 50 buildings.
