Abstract. This paper proposes a simple direct power control using space vector modulation (DPC-SVM) for three-phase threelevel neutral point clamped (3L-NPC) PWM converter connecting a wind turbine generator with grid. The active and reactive power are used as the control variables instead of the currents applied in conventional control method. Moreover, grid voltage sensors are replaced by a virtual flux (VF) estimator. The theoretical principle of this method as well as the synthesis of the active and reactive power controllers are discussed. It is shown that the proposed method exhibits several features as: simple and robust algorithm as well as simple tuning procedure of PI power controllers. Furthermore the paper presents a LCL-filter design, which fulfils IEEE-SCR 20-50 recommendation. Simulation results have proven an excellent performance and verified the validity of the proposed system.

“…INTRODUCTION Grid-voltage sensorless control has been an interesting research topic during the last decades [1]- [19]. Replacing ACvoltage sensors with estimation is a relevant option, e.g., in pulse-width-modulated rectifiers [1]- [6], since reducing the number of the sensors can improve the reliability against electrical noise and reduce costs of the system. Furthermore, the grid-voltage sensorless operation has been proposed for distributed generation [8], [9].…”

“…Furthermore, the converters may operate, at least temporarily, in unbalanced grid conditions [21], [22]. With careful design, unbalanced conditions can be also handled in grid-voltage sensorless control [4], [6], [9], [12]- [15], [19].…”

Abstract-This paper deals with grid-voltage sensorless synchronization and control under unbalanced grid conditions. A three-phase grid-connected converter equipped with an LCL filter is considered, and no other signals than the converter currents and the DC-link voltage are measured for control. An augmented adaptive state observer is proposed for estimation of the positive-and negative-sequence components of the grid voltage. The proposed observer is tested as a part of a sensorless control system. Experimental results show that the proposed method works well even in highly unbalanced grid conditions.

Summary This paper presents a control method of a three‐phase power converter operating under grid imbalance and harmonics. The proposed control system uses virtual flux of the grid, and a voltage fundamental harmonic to calculate reference instantaneous power oscillations, in order to maintain sinusoidal converter current. Thus, there is no need for symmetrical sequence decomposition. The presented method ensures current asymmetry corresponding to or opposite to voltage asymmetry, depending on the operation mode. Application of a stationary frame power control provides that the system does not require a dq transformation, and thus no grid voltage phase angle determination is needed, as the power components are the same in every coordinates system. Moreover, the power limitation method allowing limitation of the phase current amplitude was applied.
