“…When the PWM rectifier technology is applied to back to back converter, photovoltaic grid connected inverter, power active filter, and so on, the power factor of system can be improved greatly, and the harmonic and reactive pollution to the grid can be effectively reduced [1,3,4]. And then, it has a broad application prospects in modern power system and equipment [5][6][7][8].…”

“…Hereinto, direct power control (DPC) strategy has become one of the hot research topics in recent years, because of its fast dynamic response, simple structure, and high power factor, and so on [8,11,12,14,[16][17][18]. In general station, the control system of PWM rectifier contains more sensors and complex detection device, which not only increases the volume of the system device and improves the system cost, but also reduces the system reliability of three-phase PWM rectifier.…”

“…The AC current and DC voltage sensors play a crucial role in ensuring the control performance of three-phase PWM rectifier system. Even in the DPC control system of three-phase PWM rectifier, the incoming line AC current and the DC side voltage are also necessary to calculate instantaneous power variables [2,8,11,12,14,19]. And then, the two sensors are generally not to be omitted in actual application.…”

In order to achieve the low cost and high performance control of three-phase PWM rectifier, a direct power control (DPC) strategy based on a new-style virtual flux-linkage observer is proposed. The model of three-phase PWM rectifier and the principle of virtual flux-linkage vector control are introduced firstly. Then, in order to avoid the effect of integral initial value and cumulative deviation, three first-order low-pass filters are cascaded to replace the pure integral link; an improved virtual flux-linkage observer of threephase power grid is presented. From the observed virtual flux-linkage, the voltage and instantaneous power of three-phase power grid are online estimated. On this basis, the power grid voltage sensorless direct power control system of three-phase PWM rectifier is designed. Simulation results have shown that, both in the rectifying state and in the inverting state, the power grid side current and the DC side voltage of three-phase PWM rectifier all can be effectively controlled; the high power factor operation of three-phase PWM rectifier is realized.

“…MPC uses the dynamic model of the system to predict the current/power of the next moment. Compared to DPC, MPC is more accurate and effective in vector selection, of which the principle is simple and easy to implement, and it has good dynamic and static performance [4][5][6][7][8][9][10][11][12]. But one-step prediction is most used currently.…”

Aimed at the problem of DC micro grid rectifier control delay and the DC bus voltage stability, the method of two-step model predictive direct power control (TMPDPC) combined with neutral point potential control is proposed. Model predictive direct power control (MPDPC) is designed for rectifier. A cost function is then used to evaluate the active and reactive power ripples, from which the vector that generates the lowest power ripple will be applied during the next sampling interval. Two-step predictive control is designed to compensate for the delay of one-step predictive control. On the basis of this, the two-capacitor voltage unbalance problem in DC side is considered, and the neutral point potential control is added. In the Matlab/Simulink simulation, compared with control effect of direct power control (DPC) and one-step model predictive direct power control (OMPDPC), the control strategy of neutral point potential added to TMPDPC can make the system stability and control accuracy better. The validity of this scheme was validated by physical simulation at last.

“…More advanced schemes which include modulation techniques inside the FCS-MPC algorithm have been proposed [14]- [17]. In [14] FCS-MPC current control is applied to a six-phase inverter feeding an Asymmetrical Dual Three-Phase Induction Machine while in [15] a Predictive Direct Power Control is applied to a threephase voltage source converter. In [18] a Predictive Direct Torque Control (P-DTC) approach is described.…”
