摘要

快速频率响应服务旨在在几秒钟内快速平衡电网,对于管理低惯性电力系统中的突然异常具有至关重要的意义。电池系统通常作为需求端的多功能产消者,以促进快速的频率响应服务。然而,快速频率响应服务的性质导致电池的功率分布高度波动,这可能缩短其使用寿命。相比之下,住宅地区的分布式空气源热泵在支持快速频率响应服务方面具有巨大的未开发潜力。本文试图通过控制器升级将它们集成到现有服务中。我们分析了空气源热泵固有的复杂热动力学对快速频率响应服务的影响,揭示了不可预测的运行条件变化带来的控制挑战。通过${{H}_\infty }$方法调整的标准下垂控制结构解决了这一挑战,保证了在允许的工作条件范围内实际稳定地运行。最后,通过在小型低惯性住宅微电网上的多物理场仿真对所提出的快速频响服务方案进行了测试。所得结果有力地支持了所提出的新服务。

Integrating Air-Source Heat Pumps into the Demand-Side Fast Frequency Response Service: A Study Based on Thermal Dynamic Uncertainty
Fast frequency response services, designed to quickly balance the electrical grid within seconds, have a critical importance for managing sudden anomalies in low-inertia power systems. Battery systems often serve as versatile prosumers on the demand side to facilitate fast frequency response services. However, the nature of fast frequency response services leads to a highly fluctuating power profile for batteries, which can shorten their lifetime. In contrast, distributed air-source heat pumps in residential areas have a substantial untapped potential to support fast frequency response services. This paper seeks to integrate them into the existing services through a controller upgrade. We analyze the influence of air-source heat pumps' inherent complex thermal dynamics on fast frequency response services, revealing control challenges posed by unpredictable operating condition changes. Such a challenge is tackled with a standard droop control structure which is tuned through ${{H}_\infty }$ method, guaranteeing practical and stable operations within the permitted operating condition range. Finally, the proposed fast frequency response service scheme is tested through multiphysics simulations on a small-size low-inertia residential microgrid. The obtained results strongly supported the proposed new service.
