Piecewise Fryze power theory analysis applied to PWM DC–DC converters [PDF]

IET Power Electronics, 2020
This study proposes an extension to the well‐known Fryze power theory, which allows the development of a mathematical procedure that defines a global factor for the active and non‐active power processing in pulse‐width modulated (PWM) dc–dc converters. This global factor is the dc power factor.

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.

CORRECTION ALGORITHM FOR DETERMINING THE GIVEN CURRENT ACTIVE POWER FILTER BASED ON THE THEORY POWER FRYZE IN TERMS OF ASYMMETRY

Electrical Engineering and Power Engineering, 2017
Забезпечення якості електричної енергії потребує комплексного підходу до проектування та вибору фільтрокомпенсуючих та симетруючих пристроїв. На підставі аналізу відомих робіт встановлено, що формування струму фільтру здійснюється за алгоритмом в основі якого закладені елементи теорії потужності.

Multi-Label Learning for Appliance Recognition in NILM Using Fryze-Current Decomposition and Convolutional Neural Network

Energies, 2020
The advance in energy-sensing and smart-meter technologies have motivated the use of a Non-Intrusive Load Monitoring (NILM), a data-driven technique that recognizes active end-use appliances by analyzing the data streams coming from these devices.

Non‐intrusive Load Monitoring Using Gramian Angular Field Color Encoding in Edge Computing

Chinese Journal of Electronics, Volume 31, Issue 4, Page 595-603, July 2022., 2022
Non‐intrusive load monitoring (NILM) can infer the status of the appliances in operation and their energy consumption by analyzing the energy data collected from monitoring devices. With the rapid increase of electric loads in amount and type, the traditional way of uploading all energy data to cloud is facing enormous challenges.

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 ...

Domestic smart metering infrastructure and a method for home appliances identification using low‐rate power consumption data

IET Smart Cities, Volume 3, Issue 2, Page 91-106, June 2021., 2021
Abstract The deployment of domestic smart metering infrastructure in Great Britain provides the opportunity for identification of home appliances utilising non‐intrusive load monitoring methods. Identifying the energy consumption of certain home appliances generates useful insights for the energy suppliers and for other bodies with a vested interest in

Instantaneous active and reactive load signature applied in non‐intrusive load monitoring systems

IET Smart Grid, Volume 4, Issue 1, Page 121-133, February 2021., 2021
Abstract The performance of non‐intrusive load monitoring (NILM) systems heavily depends on the uniqueness of the load signature extracted from the electrical appliances. Different load signatures have been proposed. Recently, in particular, v–i trajectory feature extraction is attracting more and more attention due to its unique characteristics ...
