Control of disturbing loads in residential and commercial buildings via geometric algebra. [PDF]

ScientificWorldJournal, 2013
Many definitions have been formulated to represent nonactive power for distorted voltages and currents in electronic and electrical systems. Unfortunately, no single universally suitable representation has been accepted as a prototype for this power component.

Compensation of Budeanu’s Reactive and Complemented Reactive Currents in Extended Budeanu Theory in 3-Phase 4-Wire Systems Powered by Symmetrical Nonsinusoidal Voltage Source

Energies
The result of continuous efforts in the development of power theory, Budeanu’s power theory was successfully extended. The mathematical description that has been proposed is based on another concept, namely the Currents’ Physical Components (CPC) theory.

Budeanu’s Distortion Power Components Based on CPC Theory in Three-Phase Four-Wire Systems Supplied by Symmetrical Nonsinusoidal Voltage Waveforms

Energies
Budeanu’s power theory, in its fundamental version, describes single-phase sinusoidal and nonsinusoidal systems. Over time, this elementary description has been extended to three-phase three-wire and four-wire systems, regardless of power conditions ...

Using CPC-Based Minimizing Balancing Compensation to Reduce the Budeanu Reactive Currents Described in Extended Budeanu Theory

Energies
This article presents principles for matching reactance parameters for minimizing balancing compensation, whose mathematical origins come from the Currents’ Physical Components (CPC) theory developed by Czarnecki. The construction of minimizing balancing

Reactive Power Compensation and Distortion Power Variation Identification in Extended Budeanu Power Theory for Single-Phase Systems

Energies, 2023
This article presents methods of reactive power compensation using passive elements in the form of a capacitor (C) or choke (L) and an LC structure selected in such a way as to lead to the minimization of the reactive current (reactive power) of a single-

Determination of Inactive Powers in a Single-Phase AC Network

Energies, 2021
Based on the development of the theory of reactive power and distortion power, starting with the works of Fryze and Budeanu, it has been found that the contradictions in the definition of the components of inactive powers are caused by errors in the ...

Integration of wind power generation through an enhanced instantaneous power theory

IET Energy Systems Integration, Volume 2, Issue 3, Page 196-206, September 2020., 2020
This study deals with the operation of the wind power generation system (WPGS) having active filter capabilities using the grid‐interfacing converter (GIC) control approach. A novel current decomposition technique based on enhanced instantaneous power theory (EIPT) is suggested for controlling the GIC to realise an improved power quality (PQ) in WPGS ...

Survey on time‐domain power theories and their applications for renewable energy integration in smart‐grids

IET Smart Grid, Volume 2, Issue 4, Page 491-503, December 2019., 2019
The increasing aggregation of renewable‐based distributed generating units besides the impressive growing usage of non‐linear loads raises unwanted challenges for traditional power terms definition in power engineering. This fact consequently affected the performance of the conventional control frameworks and industrial compensation techniques. In this

Estimation of Electric Power Quantities for Nonsinusoidal Conditions Based on Operating Point Fluctuations

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes an operating point fluctuations (OPF) framework to describe nonsinusoidal, nonstationary waveforms by modeling distortions as amplitude and phase fluctuations of a time‐varying fundamental component. Based on OPF, single‐phase and three‐phase power quantity expressions consistent with IEEE Std. 1459–2025 are derived under stationary

Provenance Variation in Functional Traits of European Forest Trees: Meta‐Analysis Reveals Effects of Taxa and Age Despite Critical Research Gaps

Ecology and Evolution, Volume 15, Issue 8, August 2025.
This meta‐analysis on intraspecific variation in European trees studied the frequency of provenance variation, provenance–environment interaction, clinal variation along the climate of origin or transfer distance. While identifying trait group specific patterns of variation, research gaps have been identified in terms of age and geographical ...
