“…Other grid impedance estimation methods include variations of active and reactive powers [18], or uses a Virtual-Flux based control method to estimate inductance, [19]. An analytic approach for estimation of the coupling inductance in direct power control of active rectifiers is instead proposed in [20] and [21]. The proposed method works on the principle of assuming an equal grid voltage magnitude at two consecutive sampling instants, [21], [24], and it is integrated within the MPC algorithm.…”

-This paper presents a novel Finite Control SetModel Predictive Control (FS-MPC) approach for gridconnected converters. The control performance of such converters may get largely affected by variations in the supply impedance, especially for systems with low Short Circuit Ratio (SCR) values. A novel idea for estimating the supply impedance variation, and hence the grid voltage, using an algorithm embedded in the MPC is presented in this paper. The estimation approach is based on the difference in grid voltage magnitudes at two consecutive sampling instants, calculated on the basis of supply currents and converter voltages directly within the MPC algorithm, achieving a fast estimation and integration between the controller and the impedance estimator. The proposed method has been verified, using simulation and experiments, on a 3-phase 2-level converter.

“…Other grid impedance estimation methods are proposed in literature and are based on the variations of active and reactive powers, [18], or on the module of the grid voltage and the supply current, [19]. An analytic approach for estimation of the coupling inductance in direct power control of active rectifiers is proposed in [20] and [21]. In these works the total inductance was estimated by measuring active and reactive powers before and after a commutation instant.…”

This paper presents a novel finite control set Model Predictive Control (MPC) approach for grid-connected converters. The control performance of such converters may get affected from variations in the supply impedance, when its value is significant as compared to the converter line filter impedance. A novel idea for estimating the supply impedance variation, and hence the grid voltage, is presented in this paper. The estimation approach is based on the difference in grid voltage magnitude at two consecutive sampling instants. The grid voltage magnitudes are calculated on the basis of supply currents and converter voltages directly within the MPC algorithm, achieving a fast estimation and integration between the controller and the impedance estimator. The proposed approach has been verified using a 3-phase 2-level converter.

“…However, its operation depends on the proper design of the controllers and the accuracy of the current components separation [3], [4]. Related to these limitations, direct power control (DPC) is proposed to avoid the need for current regulations and it leads to direct control of active and reactive powers [5]. In DPC strategy, there are no internal current loops or modulator block, since the converter switching states are selected via a switching table [2].…”

“…An adaptive line parameters identification based on least squares algorithm is proposed in [7], where the estimated parameters are used in predictive-DPC of PWM rectifier. Two methods, analytic and iterative, are also presented in [5] for online estimation coupling inductance in DPC strategy of PWM rectifier. The authors in [8] proposed a fuzzy logic controller based method to compensate the unknown grid-side inductance used in an active-front-end converter control strategy.…”

A new method for adaptive ac filter parameters identification of three phase pulse-width modulated rectifiers is presented in this paper. The proposed method is based on three adaptive linear neurons to identify online the ac filter resistances and inductances. The main advantage of this method is its simplicity and it requires low computational cost. The identification algorithm is implemented and three experimental tests have been realized in order to identify in real time the ac filter resistances and inductances. First test is performed in steady state operation. Two other tests are conducted to testing the track ability of the proposed method relative to parameters variations. Experimental results demonstrate that the proposed method provides accurate ac filter parameter values and tracks well the parameters variations. The obtained parameter values can be exploited for diagnosis purposes of ac filter status or in a control strategies.
