Summary:
To secure wireless communication services, we are researching and developing disaster-resistant and environmentally friendly green base stations. One effective disaster countermeasure in carriers is to make backup time long for base stations during a power outage. Therefore, we have developed a photovoltaics (PV) system for green base stations to prolong the backup. In this paper, we propose a power control method that realizes long-term autonomous operation by PV and lithium-ion batteries (LiB) and regeneration operation by only PV for when commercial power is lost during a power outage and describe the results obtained at field test station.
