Mathematical modelling of smart solar heating system with the deployment of borehole thermal energy storage to increase renewable heat share in Dundee, UK.

Abstract

The chance of achieving 12% of renewable energy in heating demand by 2020 has gone, as the current RES share is almost the half of this target. The UK struggle to address this deficit, but it still needs more deployment of renewables. Solar energy has proved its viability and is going to play a significant role in increasing the share of renewable heat in domestic heating demand. What makes it more promising than before is that scientists have dealt with many challenges that weaken its growth. Namely, seasonal thermal energy storage that used to solve the mismatch between surplus solar energy in summer and high heating demand in winter. This study investigates the performance of a fully electrified smart heating system [1] that combines solar photovoltaics, borehole thermal energy storage and heat pumps, and compare the results of different sizes communities in Dundee to track the behaviour of BTES and the whole system. Different Solar Fraction and RES Percentage have been achieved with varying demands of heating and different sizes communities.
