“…The main methods for doing this are Moving Average Filter (MAF) [15], Delayed Signal Cancellation (DSC) [16][17] and MAF/DSC based algorithms such as Cascaded DSC (CDSC) and Cascaded MAF (CMAF) [18]- [21]. The use of MAF is beneficial for filtering out high frequency random noise, especially when the noise is periodical [15].…”

“…An arbitrary harmonic, which can be regarded as a periodic noise signal at a certain frequency, can be eliminated completely by MAF with a properly designed window length. The DSC method with a time delay of a quarter grid cycle is proposed in [16] to eliminate the effects of the 2nd harmonic in the d-q frame. This improves the accuracy of synchronized phase in distorted utilities.…”

“…As a result, the high-order harmonics cannot be eliminated adequately [22]. The linear interpolation method proposed in [16], [17] can partially mitigate the discretization error at the cost of increased computational effort. The authors of [22] pointed out that DSC based algorithms provide higher design flexibility than MAF based algorithms.…”

“…However, MAF based algorithms require minimum computational effort for implementation [23]. To eliminate a group of specific harmonics, the existing MAF/DSC based algorithms cannot achieve the shortest possible response time [16], [22]. This issue can be solved by the proposed Enhanced MAF (EMAF) and Enhanced DSC (EDSC) algorithms.…”

The harmonic components of grid voltage result in oscillations of the calculated phase obtained via phase synchronization. This affects the security and stability of grid-connected converters. Moving average filter, delayed signal cancellation and their related harmonic elimination algorithms are major methods for such issues. However, all of the existing methods have their limitations in dealing with multiple harmonics issues. Furthermore, few studies have focused on a comparison and evaluation of these algorithms to achieve optimal algorithm selections in specific applications. In this paper, these algorithms are quantitatively analyzed based on the derived mathematical models. Moreover, an enhanced moving average filter and enhanced delayed signal cancellation algorithms, which are applicable for eliminating a group of selective harmonics with only one calculation block, are proposed. On this basis, both a comprehensive comparison and a quantitative evaluation of all of the aforementioned algorithms are made from several aspects, including response speed, required data storage size, sensitivity to sampling frequency, and elimination of random noise and harmonics. With the conclusions derived in this paper, better overall performance in terms of harmonic elimination can be achieved. In addition, experimental results under different conditions demonstrate the validity of this study.

In order to eliminate the ripple of the active power and suppress the negative sequence current produced during the charging process of the tramcar under both balanced and unbalanced power supply conditions, a novel proportional integral resonance based sliding mode (PIRSM) control scheme is proposed in this article for the VIENNA rectifier of the charging station. After deriving the power model in the stationary coordinate system, the mathematical model of the VIENNA rectifier under unbalanced power supply is built. Subsequently, a unified control objective is introduced to make the proposed scheme available for different operating condition without changing the algorithm. Moreover, the resonance control and sliding mode control are combined together to construct the sliding mode surface, and the control law are derived based on the stability requirement to make the system approach its desired operating point with expected trajectory. Experimental results show that compared to the conventional PI control, the proposed control can ensure the better power tracking performances and higher power quality under different power supply conditions.
