摘要:

蜂窝运营商储能的创新性使用增强了智能电网的韧性和效率。传统上,这些储能用于在电网停电期间确保蜂窝基站(BSs)的不间断运行,现在它们可以动态参与能源灵活性市场。这种双重利用提高了基站储能系统的经济可行性,并支持可持续能源管理。在本文中,我们探索了基站储能支持电网辅助服务的潜力,方法是分配其一部分容量,同时确保超可靠低延迟(URLLC)要求,例如满足延迟和可靠性要求。这包括在高需求时段将基站存储的能量回馈电网,或为基站供电以调节电网频率。我们研究了URLLC要求对电网频率调节的影响,并制定了一个联合资源分配问题。该问题在考虑电池老化和循环约束的同时,最大化蜂窝网络的总收益,既考虑通信网络中的总速率,也考虑基站储能参与频率调节。仿真结果表明,一个拥有1500个基站的网络通过将可靠性从10^(-8)降低到10^(-3),可以将功率空缺补偿从31%提高到46%。对于-30 MW的功率空缺,这一补偿从9.3 MW变化到13.5 MW,超过了一台风力涡轮机的容量。

英文摘要:

The innovative use of cellular operator energy storage enhances smart grid resilience and efficiency. Traditionally used to ensure uninterrupted operation of cellular base stations (BSs) during grid outages, these storages can now dynamically participate in the energy flexibility market. This dual utilization enhances the economic viability of BS storage systems and supports sustainable energy management. In this paper, we explore the potential of BS storages for supporting grid ancillary services by allocating a portion of their capacity while ensuring Ultra Reliable Low Latency (URLLC) requirements, such as meeting delay and reliability requirements. This includes feeding BS stored energy back into the grid during high-demand periods or powering BSs to regulate grid frequency. We investigate the impacts of URLLC requirements on grid frequency regulation, formulating a joint resource allocation problem. This problem maximizes total revenues of cellular networks, considering both the total sum rate in the communication network and BS storages participation in frequency regulation, while considering battery aging and cycling constraints. Simulation results show that a network with 1500 BSs can increase power vacancy compensation from 31% to 46% by reducing reliability from 10^(-8) to 10^(-3). For a power vacancy of -30 MW, this varies from 9.3 MW to 13.5 MW, exceeding a wind turbines capacity.
