Abstract: To address issues such as power imbalance, low energy utilization, and insufficient supply stability caused by decentralized control of multiple electrical devices in smart microgrids, a hierarchical collaborative control approach is proposed. A three-level control model of “device layer–coordination layer–system layer” is constructed, incorporating strategies for distributed generation forecasting, energy storage optimization, and controllable load scheduling. Simulation results verify the effectiveness of the method. The study demonstrates that this technology significantly improves the economic efficiency, stability, and renewable energy integration of microgrids, providing reliable technical support for engineering applications.
