Harmonic Loads Classification by Means of Currents’ Physical Components

open access: yesEnergies, 2019
Electric load identification and classification for smart grid environment can improve the power service for both consumers and producers. The main concept of electric load identification and classification is to disaggregate various loads and categorize

Currents’-Physical-Component-Based Reactive Power Compensation Optimization in Three-Phase, Four-Wire Systems

open access: yesApplied Sciences
In this paper, we aim to address the limited capacity of compensation devices by enhancing their utilization rate by applying the currents’ physical component (CPC) theory for reactive power optimization in three-phase four-wire systems.

Currents’ Physical Components (CPC) in systems with semi-periodic voltages and currents

open access: yes, 2015
There are situations in electrical distribution systems where voltages and currents cannot be regarded as periodic quantities. They could be non-periodic. Nonetheless, properties of electrical systems confine this non-periodicity of voltages and currents

ORTHOGONAL COMPONENTS OF THE THREE-PHASE CURRENT AT ASYMMETRICAL ACTIVE-REACTIVE LOAD IN 4-WIRE CIRCUIT

open access: yesElectrical engineering & Electromechanics, 2016
Purpose. For the unbalanced sinusoidal mode with asymmetric voltage in 3-phase 4-wire to receive the orthogonal 4-component decomposition of 3-phase current, are classified symmetry/asymmetry of active and reactive load elements separately.

Currents' physical components (CPC) concept in wind farm harmonic current studies [PDF]

open access: yes, 2011
Very little information about actual wind farm harmonic measurements is available in the literature. This paper analyzes the harmonic measurements of an 18 MW wind farm with the CPC concept to determine if they are consumed or injected by the wind ...

Problems in Modeling Three-Phase Three-Wire Circuits in the Case of Non-Sinusoidal Periodic Waveforms and Unbalanced Load

open access: yesEnergies
Asymmetry in the supply voltage in three-phase circuits disrupts the flow of currents. This worsens the efficiency of the distribution system and increases the problems in determining the mathematical model of the energy system. Among many power theories,
