Adaptive Split-Frequency Quantitative Power Allocation for Hybrid Energy Storage Systems

IEEE Transactions on Transportation Electrification, 2021
As the two classical power allocation methods in battery-supercapacitor hybrid energy storage systems, split-frequency methods and power-level methods have been developed separately for many years.

Subcarrier and Power Allocation in OFDM-NOMA VLC Systems

IEEE Photonics Technology Letters, 2021
We propose a novel subcarrier and power allocation method to improve both the throughput and user fairness in orthogonal frequency division multiplexing non-orthogonal multiple access visible light communication (OFDM-NOMA VLC) systems.

Cooperative optimization of shore power allocation and berth allocation: A balance between cost and environmental benefit

, 2021
Shore power is the use of shore-side electricity to satisfy ships’ electricity demand during berthing at ports. It is an effective measure of reducing the emissions produced by auxiliary engines of ships at berth.

Joint Optimization of Handover Control and Power Allocation Based on Multi-Agent Deep Reinforcement Learning

IEEE Transactions on Vehicular Technology, 2020
In this paper, we study the handover (HO), and power allocation problem in a two-tier heterogeneous network (HetNet), which consists of a macro base station, and some millimeter-wave (mmWave) small base stations.

Uplink Fractional Power Control and Downlink Power Allocation for Cell-Free Networks

IEEE Wireless Communications Letters, 2020
This letter proposes respective policies for uplink power control and downlink power allocation in cell-free wireless networks. Both policies rely only on large-scale quantities and are expressed in closed form, being therefore scalable.
