Research on Optimization of Microgrid Backup Power Supply Strategies for Multiple 5G Base Station Clusters Under the Virtual Power Plant Architecture
摘要
As intermittent renewable energy sources like wind and photovoltaic (PV) power are increasingly integrated into power grids, they pose mounting challenges to operational resilience and stability. Virtual Power Plants (VPPs), as a viable approach for integrating and coordinating distributed energy resources (DERs), demonstrate substantial potential in boosting grid regulation capacities. Meanwhile, the mass deployment of 5G base stations driven by advancements in 5G communication technology has enabled their backup energy storage systems to participate in grid regulation while safeguarding communication reliability. Integrating 5G base station clusters with renewable energy sources such as distributed PV can form base station cluster microgrids. This paper establishes a multi-objective co-optimization model centered on economy and security for multi-5G base station cluster microgrids under the VPP framework, and conducts in-depth research on power backup optimization strategies for such microgrids incorporating self-consumed PV and energy storage systems. The findings suggest that the proposed multi-objective optimization model can offer theoretical support and technical pathways for stable operation and resilience management of power systems amid high-proportion renewable energy integration.
