“…(Ahmed et al, 2008) discusses the compensation of the controller delays by applying Kalman filters. The synchronization, a key issue in distributed generation systems based on inverters, is discussed in (Cardoso et al, 2008). Special attention must be paid to applications where precision is a main issue, such as power converters for compensation of electrical grid disturbances.…”

“…Various methods identified in the literature include the space vector filter (SVF) [17]; Kalman filtering methods [18][19][20][21] and Least Square Estimation methods (WLSE) which has a fast response time and works well with frequency variations [20,[22][23][24][25]. The one regarded as the most stable open-loop method is based on the Discrete Fourier Transform (DFT) [24,26], due to its extended data window length.…”

Abstract--This paper presents a novel synchronization technique which can identify the grid voltage frequency and phase angle under unbalanced grid voltage conditions. The method combines the features of two different energy operator schemes: the basic one for estimating the frequency of the grid voltages and the cross-energy operator for phase tracking. Using a moving data window of five samples the algorithm can track the fundamental frequency and phase angle quickly and accurately. The paper discusses the fundamental principles of the method, highlights its features and filter requirements in implementation. An experimental implementation of this method is presented which validates its performance for practical operation. The ability of the proposed method to enable a STATCOM riding-through unbalanced grid voltage condition is verified by the results from a power network simulation study.

“…This parametric methods offer higher resolution and better accuracy compared to the non-parametric methods [16]. KF estimator is one of the methods that fall into the parametric method category which have been widely studied and used for different applications [16][17][18][19][20][21][22][23]. In active power filter, KF is used to estimate and track the current harmonics of the grid which reported in [24][25][26].…”

-This paper presents a new technique of reference current generator based on Kalman filter (KF) estimator for three-phase shunt active power filter (APF). The stationary reference frame (d-q algorithm) is used to transform the load currents into DC component. The harmonics of load currents are extracted and the three-phase reference currents are generated using KF estimator. The work is simulated using Matlab/Simulink platform. To validate the simulation results, an experimental test-rig have been perform using real-time control dSPACE DS1104. In addition, hysteresis current control was used to generate the switching signal for the correction of the harmonics in the system. The nonlinear load were constructed with three-phase rectifier which connected in series with inductor and parallel with resistor and capacitor. The results shows that the new technique of shunt APF embedded with KF is proven to eliminate the harmonics created by the non-linear load with some improvement on the total harmonics distortion (THD).
