基于混合能源的无线蜂窝网节能管理机制

Energy-Saving Management Mechanism Based on Hybrid Energy Supplies for Wireless Cellular Networks

针对当前蜂窝网中基于混合能源的节能方法较为缺乏的现状,从小区粒度的角度提出了一种新的节能管理机制.该机制首先建立了多能源共存时的节能优化模型,并对业务质量评估方法进行了建模;之后针对节能优化模型,从小区补偿的角度提出了区域化的节能算法.通过在通用移动通信系统城区场景中的仿真,验证了该机制能在保证区域覆盖和业务质量的基础上降低区域的干扰,并节约电网近35%的能耗,具备很强的绿色经济价值.

The energy-saving methods are infrequent on hybrid energy supplies,a new energy-saving management mechanism from cell viewpoint was proposed. The mechanism firstly constructs energy-saving optimization model with hybrid energy supplies and modeling evaluation method for service quality. To resolve the optimization model,a regional energy-saving algorithm from the perspective of cell compensation was analyzed thereafter. Through simulations under urban universal mobile telecommunications system scenarios,it is shown that the mechanism can keep coverage and service quality on acceptable levels,reduce regional interference distributions,and saving about 34% energy for power grid,which takes on significant green economic importance.
