Optimal capacitor allocation in power systems
Computers & Electrical Engineering, 1983Abstract Static capacitors are installed at specific locations in large power systems for minimising power losses and to ensure quality of the supply system. It has been found that the number of units in each capacitor bank can be considerably reduced by suitable choice of transformer tap settings and generator voltage magnitudes, thereby reducing ...

Adaptive subcarrier allocation, power control, and power allocation for multiuser FDD-DMT systems
2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004This paper considers the problem of adaptive subcarrier allocation, power control, and power allocation for multiuser frequency division duplex-discrete multitone (FDD-DMT) systems in a Gaussian interference channel. Assuming perfect knowledge of all channel and crosstalk transfer functions, we formulate the problem as an optimization problem to ...

Power Allocation for OFDM Transmission with DF Relaying
2008 IEEE International Conference on Communications, 2007In this paper we consider an OFDM (orthogonal frequency division multiplexing) transmission scheme with a relay. Symbols sent by the source may or may not be retransmitted during a second time slot by the relay, which is assumed to be of the decode-and-forward (DF) type. For each carrier the destination implements maximum ratio combining.

On energy efficient power allocation for power-constrained systems
2014 IEEE 25th Annual International Symposium on Personal, Indoor, and Mobile Radio Communication (PIMRC), 2014Recently, the energy efficiency (EE) has become an important factor when designing new wireless communication systems. Due to economic and environmental challenges, new trends and efforts are oriented toward “green” communication especially for energy-constrained applications such as wireless sensors network and cognitive radio. To this end, we analyze

Optimization of the regional allocation of wind power capacity
2019 International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET), 2019With the growing impact of global warming and depletion of fossil fuels, the necessity of renewable energy resources is becoming more and more obvious. However, investing in intermittent renewable resources, such as wind power, by only considering the regional power potentials jeopardizes system reliability and increases the necessity of spinning ...

Power allocation for massive MIMO: impact of power amplifier efficiency
Science China Information Sciences, 2015With the rapid development of information technology, massive MIMO is becoming attractive for the fifth generation (5G) communication because of its outstanding performance in both spectral efficiency (SE) and energy efficiency (EE). Recently, many algorithms have been proposed to improve the EE while achieving high SE in massive MIMO systems.

Power Allocation Algorithms of PoE for On-Demand Power Supply
2013 IEEE 37th Annual Computer Software and Applications Conference Workshops, 2013An on-demand power supply network is proposed in i-Energy project as a method to achieve the goal of powersaving in home. In the on-demand power supply network, power requests of devices are classified by priority of Quality of Life. When each device requires power, the device sends a power request message which contains required power and the priority

Robustness of Power-Imbalance Allocation Control for Power Systems
2019 IEEE 15th International Conference on Control and Automation (ICCA), 2019We investigate the performance and robustness to noise of a centralized control called Power-Imbalance Allocation Control (PIAC) for secondary frequency control of a power system. The noise affects the frequency measurements and the communications. The impact of the noise on the synchronous state of the system is investigated.
