Power components in a system with sinusoidal and nonsinusoidal voltages and/or currents

Multivectorial strategy to interpret a resistive behaviour of loads in smart buildings

“…From (5) and (11), the apparent power multivector and the apparent power Budeanu's are respectively With regard to the power factor improvement, let consider that a capacitive susceptance B C is connected to the load terminals of the elementary building circuit in Fig. 3.…”

“…Both approaches were criticized much later by Czarnecki [6], who suggested reject the Budeanu reactive power component [7]. Triggered by these papers many investigations appeared consequently [8][9][10][11][12][13], each shedding more light on power factor improvement. In [7] a "reactive power" was defined that permits the derivation of the value of passive linear devices to achieve a relative optimum power factor.…”

The Instantaneous Power Theory

“…Some recent power formulations that resulted in formulations similar to those given in (3.126) and (3.127) were presented by Furuhashi et al [41], Tenti et al [42,43,44], van Wyk et al [45,46,47], Depenbrock et al [10,25,40] and Czarnecki [26,27]. Although the above-described abc Theory does not go in its particularities, it tries to summarize the results of the research.…”

Design of Educational Instantaneous Powers Metering Software for Steady-State Single-Phase AC Networks

“…If the answer is yes, what is its comprehensible definition? The most recent answers to these fundamental questions can be found in [5]- [6] and have been expanded by some colleagues in their text books [7]. Many works have been proposed for instantaneous powers formulations in non-sinusoidal networks for power compensation [8]- [13].…”
