摘要:

未来能源系统的新型控制策略设计既无法直接在真实电网中进行测试,也不能仅基于当前电网状况进行评估。在这方面,需要在实验室环境中使用真实的电力系统设备进行大量测试。然而,由于即使在大规模实验中也不可能完整复现所关注的整个电网区域,硬件设置必须辅以详细的仿真来完整再现所研究的系统。本文提出了一种独特的测试环境,其中基于硬件的微电网环境与大规模实时仿真框架进行物理耦合。该设置结合了使用基于硬件的实验开发新方案以及利用实时仿真评估对大规模电力系统影响的双重优势。本文从精度和通信延迟两个方面对被测微电网环境与实时仿真之间的接口进行了评估。此外,还展示了一个测试案例,表明该方法能够测试微电网控制策略以支持电网。实验观察到,通过物理接口的通信延迟取决于仿真采样时间,并且不会显著影响硬件与仿真电网之间交互的精度。

英文摘要:

The design of new control strategies for future energy systems can neither be directly tested in real power grids nor be evaluated based on only current grid situations. In this regard, extensive tests are required in laboratory settings using real power system equipment. However, since it is impossible to replicate the entire grid section of interest, even in large-scale experiments, hardware setups must be supplemented by detailed simulations to reproduce the system under study fully. This paper presents a unique test environment in which a hardware-based microgrid environment is physically coupled with a large-scale real-time simulation framework. The setup combines the advantages of developing new solutions using hardware-based experiments and evaluating the impact on large-scale power systems using real-time simulations. In this paper, the interface between the microgrid-under-test environment and the real-time simulations is evaluated in terms of accuracy and communication delays. Furthermore, a test case is presented showing the approach's ability to test microgrid control strategies for supporting the grid. It is observed that the communication delays via the physical interface depend on the simulation sampling time and do not significantly affect the accuracy in the interaction between the hardware and the simulated grid.
