Research on Hierarchical and Zonal Dynamic Reconfigurable Resource Aggregation Technology for Virtual Power Plants

With the increasing penetration of high-proportion renewable energy in new-type power systems, Virtual Power Plant (VPP) has emerged as a critical enabling technology for aggregating distributed energy resources. However, it faces challenges in achieving flexible regulation of large-scale resources and dynamic adaptability to grid operations. This paper proposes a hierarchical and zonal dynamic reconfigurable resource aggregation technique for VPPs. By establishing a multi-layered architecture spanning “provincial-municipal-aggregator-end-user resources”, the method enables hierarchical-zonal dynamic aggregation and reconfiguration of virtual generating units. The effectiveness of the proposed hierarchical-zonal strategy is demonstrated through frequency regulation scenario. The research outcomes provide theoretical foundations and practical references for VPP applications in electricity markets and grid control operations.
