研究目的
To secure wireless communication services by developing disaster-resistant and environmentally friendly green base stations with a focus on prolonging backup time during power outages using PV systems and LiB.
研究成果
The study demonstrates that weathercast-linked control in green base stations can improve the self-generation rate and extend service time during power outages. Future work will focus on enhancing the service-time extension effect and promoting the technology's broader adoption.
研究不足
The study is constrained by the variability of weather conditions affecting PV power generation and the practical limitations of LiB capacity and cost. Further optimization is needed to balance environmental contributions with disaster countermeasures.
