New Heuristic Strategies for Reactive Power Compensation of Radial Distribution Feeders
(
IEEE
, 2002 , Article)
In this paper, the authors introduce two new heuristic techniques for reactive power compensation in radial distribution feeders. The methods can be considered as generalization ideas that emerged from recent heuristic ...
Long-term electric peak load forecasting for power system planning: A comparative study
(
King Fahd University of Petroleum and Minerals
, 2004 , Article)
A comparative study between two static estimation algorithms, namely least error squares (LES) and least absolute value (LAV) algorithm was presented. The proposed algorithm used the past history data for the load and the ...
Identification of individual types of harmonic loads in an electric power system bus
(
Elsevier
, 2004 , Article)
Some buses in a power system feed power to loads that are sources of harmonics. This type of bus is called a complex bus. This paper provides a new application of the constrained least absolute value algorithm (LAV) to ...
Frequency and harmonics evaluation in power networks using fuzzy regression technique
(
IEEE Computer Society
, 2001 , Conference Paper)
A new technique for frequency and harmonic evaluation in power networks is proposed in this paper. This technique is based on fuzzy linear regression and uses the digitized voltage samples, which are fuzzy numbers, to ...
Fuzzy linear parameter estimation algorithms: A new formulation
(
Elsevier
, 2002 , Article)
In this paper, we present a new formulation of a fuzzy linear estimation problem as one of the linear programming where the objective is to minimize the spread of the data points, subject to constraints on each measurement ...
Power system frequency estimation based on simulated annealing: A variable frequency model
(
Sharif University of Technology
, 2004 , Article)
This paper presents a new technique for measuring power system frequency, rate of change of frequency and the voltage amplitude and phase angle using the Simulated Annealing (SA) based optimization algorithm. The algorithm ...

Park's transformation application for power system harmonics identification and measurements
(
Taylor & Francis
, 2003 , Article)
This paper presents the application of Park's transformation for identifying and measuring power system harmonics. One of the advantages of the proposed technique is that it does not need a model for the harmonics components ...
On the application of αβ-transformation for power systems frequency relaying
(
Institute of Electrical and Electronics Engineers Inc.
, 2001 , Conference Paper)
This paper presents a new and very accurate algorithm for power system frequency measurement. The proposed algorithm is based on αβ-transformation of the three phase voltages or current waveforms in the relay location, ...
Effects of harmonic distortion on the active and reactive power measurements in the time domain: A single phase system
(
IEEE Computer Society
, 2001 , Conference Paper)
A new application of the least error squares (LES) estimation algorithm is given for identifying, in the time domain, the active and reactive power from available samples of voltage and current waveforms. The digital ...
