| As a micro-energy carrier of the "source-grid-load-storage" collaborative interaction, the smart park"s participation in grid auxiliary frequency regulation has gradually become an important supporting force for enhancing the safety and stability of the power grid. However, the research and development of related technologies in both software and hardware face challenges such as high costs, long verification cycles, and low credibility of product functions. This study has developed a hardware-in-the-loop test platform for smart parks" participation in grid frequency regulation based on a cloud-edge collaborative architecture. The platform adopts a three-layer architecture of "digital twin layer - edge computing layer - cloud interaction layer". The digital twin layer builds a 1:1 mapping model with RTDS as the core to collect multi-dimensional data. The edge computing layer realizes multi-time-scale energy management and rapid frequency regulation control through edge terminals. The cloud interaction layer provides full-process visual monitoring and evaluation. Meanwhile, a multi-virtual device data interaction mechanism is designed to solve the problems of low compatibility of GTNET hardware boards and limited access to external devices. Experimental tests show that the proposed test platform can achieve dynamic collaboration and regulation strategy multi-scenario closed-loop verification of frequency regulation resources within the park, providing more comprehensive test support for the large-scale application of smart park frequency regulation technology. |
