Resilient Island Partitioning for Renewable-Rich Meshed Grids: A BFS-EEMD Approach
Xudong Song, Jinhua Huang, Dong Liu · 2025
This study proposes a flexible island partitioning strategy to address DG fluctuations and load restoration prioritization in meshed distribution networks with high renewable penetration. By integrating a BFS-based initial islanding scheme with load features extracted via EEMD, the strategy ensures stable power supply in islanded zones while prioritizing critical loads for grid stability. Case simulations under varying solar radiation and wind speed conditions demonstrate the method's adaptability to DG output changes. Simulations on a CPS109-node distribution network validate its effectiveness in maintaining supply-demand balance during photovoltaic generation decline and wind power penetration increase. Results confirm the strategy's technical feasibility for resilient power management in renewable-dominated grids.
