Reactive power control for real power-loss minimization

IEEE Computer Applications in Power, 1988
An accurate and fast technique for real-time control of system voltage and reactive power of large-scale power systems is presented. The one-bus-away method has been modified to obtain accurate results with moderate computer requirements for online application to large-scale power networks.

Minimization of real power losses using reactive power control

Electric Power Systems Research, 1989
Abstract Reactive power control in a power system is useful to improve the voltage profile and reduce the system power losses. The power loss is minimized with VAR sources as control variables (capacitors/inductors, SVSs and generator reactive powers) and variable transformer tap ratios. The constraints are on the bus voltage magnitudes.

Decomposition approach for minimising real power losses in power systems

IEE Proceedings C Generation, Transmission and Distribution, 1991
An efficient method for minimising real power losses and improving the voltage profile of large scale power systems is presented. The problem is solved through optimal adjustments of reactive power generation in the system by changing generator voltages, shunt capacitors, and tap setting of tap changing transformers.

Real Power Loss Allocation Using Modified Nodal Equations

Australian Journal of Electrical and Electronics Engineering, 2009
This paper proposes a new method to identify the real power loss allocations caused by generators and loads using modified nodal equations. Based on solved load flow results, the method partitions the Y-bus matrix to decompose the current of the load buses as a function of the generators' currents and load voltages. Then it uses the modified admittance

Contingency selection based on real power transmission losses

PowerTech Budapest 99. Abstract Records. (Cat. No.99EX376), 2003
This paper presents two new performance indices for contingency analysis in a composite electric power system. The proposed indices are derived from active power transmission losses that do not require additional parameters. They can be used effectively for line overloading and bus voltage limit violation performance indices.

Signal Losses With Real-Time Three-Dimensional Power Doppler Imaging

Ultrasound in Medicine & Biology, 2007
Power Doppler imaging (PDI) has been shown to be influenced by the wall filter when assessing arterial stenoses. Real-time 3-D Doppler imaging may likely become a widespread practice in the near future, but how the wall filter could affect PDI during the cardiac cycle has not been investigated.

Real power loss reduction by North American sapsucker algorithm

International Journal of System Assurance Engineering and Management, 2021
In this paper North American Sapsucker (NAS) algorithm has been projected to solve the loss lessening problem. Proposed NAS is designed based on the deeds of sapsucker mating. Male sapsucker will make a unique sound to attract the female sapsucker. In the proposed algorithm male and female sapsuckers are the candidate solutions.

A real-time innovative scheme for power losses calculation

IEEE Power and Energy Society Conference and Exposition in Africa: Intelligent Grid Integration of Renewable Energy Resources (PowerAfrica), 2012
In the deregulated electricity market, electric utilities aim to satisfy the electricity demand and simultaneously to increase their profit. In order to satisfy both objectives, electric utilities should provide electricity reliably to the customers in a cost effective way.
