Abstract

The coupling of the heat and power sector is required as supply and demand in the German electricity mix drift further and further apart with a high percentage of renewable energy. Heat pumps in combination with thermal energy storage systems can be a useful way to couple the heat and power sectors. This paper presents a hardware-in-the-loop test bench for experimental investigation of optimized control strategies for heat pumps. 24-hour experiments are carried out to test whether the heat pump is able to serve optimized schedules generated by a MATLAB algorithm. The results show that the heat pump is capable of following the generated schedules, and the maximum deviation of the operational time between schedule and experiment is only 3%. Additionally, the system can serve the demand for space heating and DHW at any time. Keywords—Heat pump, Energy management, SG ready, Thermal energy storage, Control strategy, Optimization, hardware-in-the-loop

使用热能储存提供灵活性的热泵优化控制与快速控制原型和SG准备标准

由于可再生能源的比例很高，德国电力结构中的供需差距越来越大，因此需要热电部门的耦合。热泵与热能储存系统相结合可以成为热电耦合的有效方法。本文提出了一种用于热泵优化控制策略实验研究的硬件在环试验台。通过24小时的实验，测试热泵是否能够服务于MATLAB算法生成的优化调度。结果表明，热泵能够按照生成的计划运行，计划运行时间与实验运行时间的最大偏差仅为3%。此外，该系统还可以随时满足空间供暖和DHW的需求。关键词:热泵，能量管理，SG ready，热能储存，控制策略，优化，硬件在环
