【摘要】 针对微电网群协同优化需求，构建了一种基于交替方向乘子法(ADMM)的分布式双层能量管理模型。系统上层通过功率交互协调机制实现微电网群整体经济性优化，下层依托自主决策模型完成各子微网内部分布式电源的优化控制。相较于传统集中式优化，所构建的双层框架通过分解协调机制提升了计算效率，并保持系统运行的灵活性。典型案例测试结果表明，该策略在保证收敛精度的前提下，可显著提升多微电网系统的经济运行水平，为解决高渗透率新能源场景下的群组协同问题提供了新的技术路径。更多还原

【Abstract】 To address the coordinated control requirements of multiple microgrids, this paper develops a distributed two-tier energy management framework based on the alternating direction method of multipliers(ADMM). The upper tier optimizes the overall economic performance of microgrid clusters through a power exchange coordination mechanism, while the lower tier implements detailed management and control of distributed energy resources within individual sub-microgrids via autonomous decision-making models. Compared to traditional centralized optimization approaches, the proposed framework enhances computational efficiency through a decomposition-coordination mechanism while maintaining operational flexibility. Case study results demonstrate that the proposed strategy significantly enhances the economic performance of multi-microgrid systems while ensuring convergence accuracy, providing a new technical pathway to address collaborative challenges in scenarios with high penetration of renewable energy.更多还原
