This article presents an alternative finite control set model predictive control (FCS-MPC) implementation to reduce the input current ripple of a two-level three-phase grid-connected rectifier. With the proposed approach, an improvement in the input current ripple is obtained by integrating the virtual vectors in the conventional FCS-MPC structure. The synthesis of the virtual vector is conceptualised from the discrete space vector modulation approach which combines several switching states during the sampling period to create new virtual voltage vectors. However, with this approach, the number of voltage vectors becomes higher, making it challenging to implement this algorithm in a standard control platform. To overcome this problem, a two-stage optimisation method is proposed to optimise the voltage vector selection process, avoiding evaluating all the feasible voltage vectors without any performance sacrifice. Experimental results are presented; showing that the proposed technique provides lower input current ripple compared to the conventional FCS-MPC with an acceptable computational effort.

“…To improve the aforementioned performance indexes, a number of control algorithms, such as deadbeat control [12,13], repetitive control [14,15], proportional-resonant with damping control method [1,[16][17][18], sliding mode control [3,19,20], hysteresis control [21], predictive control [22,23], adaptive control [24], optimal control [25], and passivity-based control (PBC) [26], have been proposed for VSIs. Among these control techniques, the PBC is a hybrid control scheme combined with the instruction predicting feedforward control, the disturbance feedforward control, the decoupling control, and the negative feedback control.…”

The multi-frequency Passivity-Based Control (PBC) has been successfully applied in L-filtered power converters. For an LC-filtered stand-alone voltage source inverter (VSI), the mathematical model is second-order, where two state variables are used in modeling and control in conventional multi-frequency PBC controller, complicating the controller design and increasing the occupied resources both in hardware and software. In order to simplify the controller design and save the resources as well as the cost, a control scheme called multi-frequency single-loop PBC is proposed for the LC-filtered stand-alone VSI in this paper. The feasibility of the proposed control strategy is verified through the experimental results on a 3-phase/110 V/6 kW prototype.

“…This feature of the FCS-MPC technique can provide control flexibility for an MG application. Predictive current control (PCC), which was proposed in [35,36], can be used for a grid-feeding converter in grid-connected mode. It also can be used in islanded mode if the MG system has a grid-forming converter.…”

Direct Phase Angle and Voltage Amplitude Model Predictive Control of a Power Converter for Microgrid Applications

et al. 2018

Several control strategies of the finite control set model predictive controls (FCS-MPC) have been proposed for power converters, such as predictive current control (PCC), direct predictive power control (DPPC), and predictive voltage control (PVC). However, for microgrid (MG) applications, the control strategy of the FCS-MPC for a power converter might be changed according to the operation mode of the MG system, which results in a transient response in the system voltage or current during the mode transition. This study proposes a new control strategy of FCS-MPC for use in both islanded and grid-connected operation modes of an MG system. Considering the characteristic of a synchronous generator, a direct phase angle and voltage amplitude model predictive control (PAC) of a power converter is proposed in this study for MG applications. In the islanded mode, the system frequency is directly controlled through the phase angle of the output voltage. In the grid-connected mode, a proportional-integral (PI) regulator is used to compensate for the phase angle and voltage amplitude of the power converter for constant power control. The phase angle of the system voltage can be easily adjusted for the synchronization process of an MG system. A comparison study on the proposed PAC method and existing predictive methods is carried out to show the effectiveness of the proposed method. The feasibility of the proposed PAC strategy is evaluated in a simulation-based system by using the MATLAB/Simulink environment.
