Potential Use of Fryze’s Approach-Based Power Theories in Waveform Distortion Contribution Assessment

Abstract

This paper explores the potential of some remarkable power theories derived from Fryze’s approach to assessing waveform distortion contributions. The analysis is limited to a simplified system composed of one load and one voltage source connected by a point of common coupling. Finally, some keys to assess are proposed for two types of systems: strong networks (traditional distribution systems) and weak networks (islanded microgrids).

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

“…Since then, the d-q method derived from this theory has been widely used in the design of power electronic devices [9,10]. Other time domain power theories include Fryze power theory [11], Fryze-Buchholz-Dpenbrock (FBD) power theory [12,13], conservative power theory (CPT) [14], etc. The main frequency domain power theory is the Budeanu power theory, while the main time-frequency domain power theory is the currents' physical component (CPC) power theory [15][16][17][18][19].…”
