本研究调查了与季节性运行热电厂的冷却塔耦合的含水层热能储存系统（ATES）的性能。在热电厂运行期间，ATES为冷却塔提供冷水并储存热水。此外，它还在热电厂停机期间为洗浴或灌溉提供温水。对ATES的性能进行了全年的数值评估，并优化了布井。研究结果表明，ATES系统可以通过将冷却水供应井定位在存储井的上游来优化。在优化的ATES中，冷水供应井的流出温度可以保持在15 °C以下，这满足了冷却塔的温度要求。以8400 m3/d的速度注入热水（温度为70 °C）6个月，导致含水层中储存超过14万m3的温水（温度≥ 40 °C）。这些热水至少可以提供12,000 m3/d的热水，持续6个月。恢复效率估计为60.9%，能量损失归因于降雨入渗，热扩散到下伏低渗透层和下游平流。
This study investigates the performance of an aquifer thermal energy storage system (ATES) that is coupled with the cooling tower of a seasonally-running thermal plant. The ATES supplies cool water and stores heated water for the cooling tower during the runtimes of the thermal plant. Moreover, it supplies warm water for bathing or irrigation during downtimes of the thermal plant. The performance of ATES is evaluated numerically for a full year, and well placement is optimized. Findings indicate that the ATES system could be optimized by locating the cool water supply well upstream of the storage well. In the optimized ATES, the outflow temperature from the cool water supply well can be maintained below 15 °C, which satisfies the temperature requirement for the cooling tower. The injection of heated water (with temperature of 70 °C) at 8400 m3/d for six months leads to over 140,000 m3of warm water (with temperature ≥ 40 °C) stored in the aquifer. This warm water can supply at least 12,000 m3/d of warm water for six months. The recovery efficiency is estimated at 60.9%, and the energy loss is attributed to rainfall infiltration, thermal diffusion into underlying low-permeability layer and advection downstream.
