Abstract
In this paper, a new research of seasonal thermal storage is introduced. This study aims to maximize the utilization of renewable energy source and industrial waste heat (IWH) for urban district heating systems in both heating and non-heating seasons through the use of large-scale seasonal thermal storage. Based on this research, a demonstration project of a central solar-IWH heating system with 500,000 m3 borehole thermal energy storage (BTES) is implemented in Chifeng, China. The detailed design, control strategies and optimization methods of the project is presented and discussed in this paper. The study showed that a smooth system operation with stable energy output and supplying temperature of seasonal storage could be achieved by adopting the developed control strategy.
