论文摘要
我们介绍了具有相变泥浆作为热量存储和转移介质的电加热系统的监督预测控制方法的设计，实现和实验验证。控制器优化了用作热量产生和能量分布组件的设定点的能量流。优化同时处理热子系统和电气子系统，并能够在不同的目标之间切换。我们表明，可以在低成本嵌入式硬件上实现控件，并使用一个实验测试床对其进行验证，该测试床包括完整的加热系统的安装，包括所有液压和所有电气组件。实验结果证明了两者的可行性，带有相变浆的热泵加热系统以及最佳控制方法。可以满足主要控制目标，即热舒适度和太阳能的最大自我消费。此外，系统及其控制器提供了负载转移的潜力。
We present the design, implementation and experimental validation of a supervisory predictive control approach for an electrical heating system featuring a phase change slurry as heat storage and transfer medium. The controller optimizes the energy flows that are used as set points for the heat generation and energy distribution components. The optimization handles the thermal and electrical subsystems simultaneously and is able to switch between different objectives. We show the control can be implemented on low-cost embedded hardware and validate it with an experimental test bed comprising an installation of the complete heating system, including all hydraulic and all electrical components. Experimental results demonstrate the feasibility of both, a heat pump heating system with a phase change slurry, and the optimal control approach. The main control objectives, i.e., thermal comfort and maximum self-consumption of solar energy, can be met. In addition, the system and its controller provide a load shifting potential.
