摘要:
本文介绍了一种混合H∞-被动框架,使配备热泵的区域供暖系统(DHSs)能够支持电力电网的频率调节。分析展示了DHS调节器如何影响耦合的电热频率动态,并提供了用于高效控制器设计的LMI条件。我们还提出了一种不依赖扰动的温度调节器,以确保稳定性和对热需求不确定性的鲁棒性。仿真显示,在保持DHS良好热性能的同时,电力电网的频率控制动态得到了改善。
英文摘要:
This paper introduces a mixed H-infinity-passivity framework that enables district heating systems (DHSs) with heat pumps to support electric-grid frequency regulation. The analysis illustrates how the DHS regulator influences coupled electro-thermal frequency dynamics and provides LMI conditions for efficient controller design. We also present a disturbance-independent temperature regulator that ensures stability and robustness against heat-demand uncertainty. Simulations demonstrate improved frequency-control dynamics in the electrical power grid while maintaining good thermal performance in the DHS.
