Power Control for Uplink Transmission With Mobile Users
IEEE Transactions on Vehicular Technology, 2011In this paper, we introduce an uplink transmission model with mobile users, where each user maximizes his/her utility to achieve the best performance. We propose a power allocation scheme for each mobile user when all channel information is available. Moreover, we illustrate that one user would expect to predict the aggregate interference to maximize ...

Power Control with Power Budget for Uplink Transmission in Heterogeneous Networks
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017An algorithm of power control in two-tier heterogeneous networks is proposed in this paper. We consider femtocell base stations (FBSs) dense deployment in the macrocell base station (MBS) coverage, the MBS dynamically estimates total uplink interference of femtocell user equipments (FUEs).

The unified power flow controller: a new approach to power transmission control
IEEE Transactions on Power Delivery, 1995This paper shows that the unified power flow controller (UPFC) is able to control both the transmitted real power and, independently, the reactive power flows at the sending- and the receiving-end of the transmission line. The unique capabilities of the UPFC in multiple line compensation are integrated into a generalized power flow controller that is ...

Transmission power control techniques for wireless sensor networks
Computer Networks, 2007Communication is usually the most energy-consuming event in Wireless Sensor Networks (WSNs). One way to significantly reduce energy consumption is applying transmission power control (TPC) techniques to dynamically adjust the transmission power. This article presents two new TPC techniques for WSNs.

Control Strategy of Environmental Control System in Power Transmission
2020The development of electric power technology has provided a lot of convenience for people’s lives, and people are becoming more and more dependent on electric power technology. The use of environmental control system control in power transmission is of great significance. An efficient environmental control system can not only detect the temperature and

Global controllability of the power transmission network
Proceedings of 35th IEEE Conference on Decision and Control, 2002Global controllability of 2D and 4D nonlinear models of power transmission networks governed via flexible AC transmission systems (FACTS) is studied. This suggests that control functions enter the system via coefficients. The approach employed is based on a qualitative method.

Transmission series power flow control
Proceedings of IEEE/PES Transmission and Distribution Conference, 1995This paper presents the characteristics of two gate turn-off (GTO) thyristor voltage-sourced inverter-based series power flow control devices, namely the series power flow controller (SPFC) and the unified power flow controller (UPFC). These devices represent series extensions of the STATCON, an inverter-based shunt device developed under a tailored ...

Joint beamforming and power control using continuous updates of transmission power
Digital Signal Processing, 2016The goal of algorithms for joint beamforming and power control in communication systems with antenna arrays is to minimize the transmission power while keeping the signal-to-interference-plus-noise ratio (SINR) above a minimum acceptable level. To meet this goal, one appealing approach is to first use a training sequence to adaptively obtain the ...
