Cross-Layer Design for Green Power Control [PDF]

open access: yes, 2012
In this work, we propose a new energy efficiency metric which allows one to optimize the performance of a wireless system through a novel power control mechanism. The proposed metric possesses two important features.

Optimized Power Control for Over-the-Air Computation in Fading Channels

open access: yesIEEE Transactions on Wireless Communications, 2019
Over-the-air computation (AirComp) of a function (e.g., averaging) has recently emerged as an efficient multiple-access scheme for fast aggregation of distributed data at mobile devices (e.g., sensors) at a fusion center (FC) over wireless channels.

Analysis of carbon emission, carbon displacement and heterogeneity of Guangdong power industry

open access: yesEnergy Reports, 2022
The marginal carbon emission factor can more accurately reflect the real-time carbon emission of the system. Based on the hourly output, load and external power data of Guangdong Province from 2017 to 2020, this paper uses the seemingly unrelated ...

Power Flow Control by Unified Power Flow Controller

open access: yesMehran University Research Journal of Engineering and Technology, 2020
The demand of energy usage is increasing rapidly and to meet the energy requirements, best possible transmission systems should be adopted to avoid energy losses in our transmission systems. In Pakistan’s WAPDA (Water & Power Development Authority) system, the rapid increase in load and less generation capacity has increased load shedding thought ...

Power Flow Control by Unified Power Flow Controller [PDF]

open access: yesEngineering, Technology & Applied Science Research, 2019
The demand for electricity is increasing day by day and we have to produce more electrical energy to meet the load demands. Most of the experts prefer to extend the existing electrical networks over building the new network with greater costs. In this paper, the implementation of the flexible AC transmission systems (FACTS) devices in a simple ...

Mitigating Cascading Failures in Interdependent Power Grids and Communication Networks [PDF]

open access: yes, 2014
In this paper, we study the interdependency between the power grid and the communication network used to control the grid. A communication node depends on the power grid in order to receive power for operation, and a power node depends on the ...

Adaptive reactive power control of PV power plants for improved power transfer capability under ultra-weak grid conditions

open access: yesIEEE Power & Energy Society General Meeting, 2019
The Photovoltaic (PV) power plants are usually deployed in remote areas with the high solar irradiance, and their power transfer capabilities can be greatly limited by the large impedance of long-distance transmission lines. This paper investigates first

Power-Imbalance Allocation Control of Power Systems-Secondary Frequency Control [PDF]

open access: yesAutomatica, 2018
The traditional secondary frequency control of power systems restores nominal frequency by steering Area Control Errors (ACEs) to zero. Existing methods are a form of integral control with the characteristic that large control gain coefficients introduce an overshoot and small ones result in a slow convergence to a steady state.

Optimal operation of combined heat and power systems: an optimization-based control strategy [PDF]

open access: yes, 2019
The use of decentralized Combined Heat and Power (CHP) plants is increasing since the high levels of efficiency they can achieve. Thus, to determine the optimal operation of these systems in dynamic energy-market scenarios, operational constraints and ...

Pilot Power Control for Cell-Free Massive MIMO

open access: yesIEEE Transactions on Vehicular Technology, 2018
In this correspondence paper, we consider a cell-free massive Multiple-Input Multiple-Output (MIMO) system where access points (APs) serve a much smaller number of users under the time-division duplex operation.
