Abstract: To address the limitations of traditional centralized frequency regulation approaches, which heavily relied on central nodes and faced issues such as communication latency and data privacy leakage, this study proposed a frequency regulation strategy for microgrids based on a cloud-edge collaborative architecture with participation from load-side resources. A system-level frequency regulation framework was established under the cloud-edge architecture, enabling the decomposition of regulation tasks and the effective utilization of edge computing capabilities within virtual power plants. Considering the operational characteristics of flexible load-side resources, frequency regulation models were developed for thermostatically controlled loads and electric vehicle charging stations, incorporating user satisfaction. Taking into account the risks of communication failures in cloud-edge systems, a regulation strategy was proposed that considered regulation cost, carbon emissions, and user satisfaction, while enhancing the response capability under communication disruptions. Case studies based on the IEEE 33-bus system demonstrated that the proposed method outperformed benchmark approaches in reducing regulation costs, improving user satisfaction, and lowering carbon emissions associated with frequency regulation.
