论文摘要
提高电价会激发移动网络运营商为无线电访问网络（RANS）找到新的节能解决方案。在这项研究中，我们专注于一种特定类型的RAN，其中独立太阳能电池板用作电网能的替代能源。首先，我们描述了这个基于混合能源的无线电访问网络（HEBRAN），并制定了一个优化问题，旨在降低该网络的总拥有成本。然后，我们提出了一个框架，该框架提供了一种具有成本效益的算法，用于为Hebran的太阳能电池板和电池选择适当的尺寸，并提供两个新颖的开关开/关算法，该算法可以调节网络操作过程中网格电力的消耗。此外，我们创建了一个简化的Hebran优化问题模型，以在混合整数线性编程（MILP）求解器中解决该模型。结果表明，我们的算法的表现优于MILP解决方案和经典开关打开/关闭方法。此外，我们的发现表明，迁移到Hebran系统是可行的，并且对移动网络运营商具有成本效益。
Increasing electricity prices motivates the mobile network operators to find new energy-efficient solutions for radio access networks (RANs). In this study, we focus on a specific type of RAN where the stand-alone solar panels are used as alternative energy sources to the electrical grid energy. First, we describe this hybrid energy based radio access network (HEBRAN) and formulate an optimization problem which aims to reduce the total cost of ownership of this network. Then, we propose a framework that provides a cost-efficient algorithm for choosing the proper size for the solar panels and batteries of a HEBRAN and two novel switch on/off algorithms which regulate the consumption of grid electricity during the operation of the network. In addition, we create a reduced model of the HEBRAN optimization problem to solve it in a mixed integer linear programming (MILP) solver. The results show that our algorithms outperform the MILP solution and classical switch on/off methods. Moreover, our findings show that migrating to a HEBRAN system is feasible and has cost-benefits for mobile network operators.
