Abstract

Because of its large number and wide distribution, 5G base stations can be well combined with distributed photovoltaic power generation. However, there are certain intermittent and volatility in the photovoltaic power generation process, which will affect the power quality and thus affect the operation of the base station. Energy storage technology is one of the effective measures to solve such problems. The battery-supercapacitor hybrid energy storage method is currently widely used in absorbing new energy. This article first introduces the energy depletion of 5G communication base stations(BS) and its mathematical model. Secondly, it introduces the photovoltaic output model, the power model of batteries and super capacitors(SC), and the capacity model, as well as the 5G BS hybrid energy storage system(HESS) model. Ground on the 24-hour photovoltaic power generation and load power depletion data of the 5G BS, the optimization solution is performed. The results verify the feasibility of the HESS for 5G communication BS.

考虑光伏的5G基站储能配置研究

5G基站数量多、分布广，可以很好地与分布式光伏发电相结合。但光伏发电过程中存在一定的间歇性和波动性，会影响电能质量，从而影响基站的运行。储能技术是解决这些问题的有效措施之一。电池-超级电容器混合储能方法是目前广泛应用的新能源吸收方法。本文首先介绍了5G通信基站(BS)的能量损耗及其数学模型。其次，介绍了光伏输出模型、电池与超级电容器(SC)的功率模型、容量模型以及5G - BS混合储能系统(HESS)模型。基于5G基站24小时光伏发电和负荷耗电数据，进行优化求解。结果验证了HESS用于5G通信BS的可行性。
