“…For the power calculation under nonsinusoidal conditions, Budeanu [4] and Fryze [5] first proposed the definition of power quantities, commonly referred to as power theories, based on frequency-domain or time-domain analysis, respectively. After that, the definitions of various power components have been developed by many researchers [6][7][8][9][10][11]. Among these, IEEE Standard 1459-2010 [12], as one of the most prominent power theories, provides definitions mainly based on Fourier transform analysis.…”

Due to nonlinear components in the charging piles of electric vehicles, harmonics and nonstationary signals in the electric vehicle charging load bring voltage and current distortion, seriously affecting the accuracy of the power-related calculation in nonsinusoidal environments. This paper proposed a new approach to calculate the active power and root mean square values from decomposed components using the adaptive chirp mode decomposition (ACMD) method on voltage and current. The advantage of the ACMD-based method is that it correctly provides the power-related quantities of harmonics or nonstationary components for the electric vehicle charging load. The performance of the proposed method was verified using synthetic signals and simulation tests. The experimental results presented better estimations for each quantity defined in IEEE Standard 1459-2010, compared with the discrete wavelet transform approach.

“…The commercial power meter (revenue meter) was used for the sake of comparison. In [50,51], the authors present the detail discussions about the different methods used by some electronic meters. Moreover, they discuss on some proposals to electrical energy billing (focused on reactive power/energy) under nonsinusoidal conditions.…”

This paper evaluates the impact of voltage distortion on the electrical quantities measured by revenue meters and the influences on the electrical energy billing. This is done through an experimental setup, which combines the following variables for the first time in an experiment: different total harmonic voltage distortion (THDv) levels; among these levels, different harmonic profiles; and different loads. A programmable alternating current (AC) power source was used in the laboratory to apply voltage signals in three electronic loads: a compact fluorescent lamp (CFL) and two light emitting diode (LED) lighting devices for which voltage signals with THDv 4.9%, 18.8% and 24.5% have been applied. All applied signals contain one or more harmonic order more commonly found in the low voltage grid (3rd, 5th and 7th). For these analyses, a power quality analyzer and a revenue meter were used. The results show that significant and diverse effects on the electrical quantities of individual loads will occur with different THDv levels and harmonic profiles. Comparing with a reference case (sinusoidal condition), when a distorted signal was applied, for the same THDv level, some parameters remained numerically the same, some have improved and some have become worse. This study shows that the effects of combination of the variables such as different THDv level with different harmonic profiles on electrical quantities of loads are not as clear as the effects of considering only one variable. The results of this paper shed light on such effects.

“…In [41], the authors present the new challenges in energy metering and monitoring to Chinese grids, investigating the smart metering on the smart grid context. Furthermore, in [42], the authors discuss the measurements recorded by revenue meters under nonsinusoidal conditions and conclude that different meters under the same condition have different results. Therefore, it is necessary to understand the methods used and consider only the fundamental signals, aiming the correct billing consumers.…”
