Abstract

The deployment of mobile networks has imposed an urgent requirement for the pursuit of low-carbon communication infrastructures. The increasing energy consumption of mobile networks has brought about challenges of techno-economic and environmental sustainability. Renewable energy-enabled mobile networks have received a lot of attention due to their capability to evade greenhouse gas emissions and easy availability. Microgeneration-based renewable energy provision is a feasible and effective solution for 5G networks. Dimensioning of microgeneration renewable energy power supply is an essential issue to make the system operate for a long period cost-effectively with a minimum amount of grid energy consumption. For effective deployment of microgeneration renewable energy system, it is essential to provision it with adequate PV panel capacity and storage devices. This work attempts to identify the cost-effective, energy-efficient, and emissions-aware sizing of PV panels and storage for 5G HetNet. An energy-saving strategy based on an optimal policy of advanced sleep modes and traffic-aware load offloading is developed and the interaction of the energy-saving strategy on the system dimensioning is explicitly examined. The proposed solution aims to ensure the communication quality of service whilst keeping the optimal cost-effective deployment and network operation. The system performance in terms of grid energy consumption, empty storage probability, emission performance, and total cost of the system is extensively assessed through experiments for a range of operational scenarios. The numerical results demonstrated that the proposed sustainable energy system dimensioning and operation integrated with an energy-saving strategy is energy-efficient and cost-effective.

为可持续的 5G 异构网络设计具有成本效益的微发电可再生能源供应尺寸
移动网络的部署对追求低碳通信基础设施提出了迫切要求。移动网络日益增长的能耗带来了技术经济和环境可持续性的挑战。可再生能源移动网络因其避免温室气体排放的能力和易于使用而受到广泛关注。基于微发电的可再生能源供应是 5G 网络可行且有效的解决方案。要使系统以最低的电网能耗、经济高效地长期运行,微发电可再生能源供电的尺寸设计是一个至关重要的问题。为了有效部署微型可再生能源发电系统,必须为其配备足够的光伏板容量和存储设备。本研究试图为 5G HetNet 确定具有成本效益、高能效和排放感知的光伏电池板和存储设备的尺寸。基于高级睡眠模式和流量感知负载卸载的最优策略,开发了一种节能策略,并明确研究了节能策略与系统尺寸的相互作用。所提出的解决方案旨在确保通信服务质量,同时保持最佳的成本效益部署和网络运行。通过对一系列运行场景进行实验,从电网能耗、空存储概率、排放性能和系统总成本等方面对系统性能进行了广泛评估。数值结果表明,建议的可持续能源系统尺寸和运行与节能策略相结合,既节能又符合成本效益。
