“…Hence, low order harmonic distortion can be observed in the generated output current waveforms. This low harmonic order may excite CL-filter resonance in the grid side of IBMC, which causes the output current to be highly distorted, as shown in [8]. In order to suppress the oscillation caused by filter resonance, it requires the addition of a passive damping resistor at the grid interfacing side, as suggested in [17], [18].…”

“…Thus the power exchange between the mechanical rotor and the electrical grid of SGs will not be recreated. The power command of VSG control can thus be determined with the help of the equation of the active power flow in a two-bus bar system [48] shown in (8).…”

“…Therefore, some shortcomings still exist, for instance, the resonance phenomenon of output CL-filter caused by the generation of low order harmonics components. This resonance may profoundly disturb the output current [8], so that it usually requires the addition of a passive damping resistor at the grid interfacing side [17], [18]. The existing modulation methods also only utilize the information of the phase angle to control the CSI side, and the amplitudes of output values cannot be regulated directly due to the fact that zero current vectors are not be used in the CSI side of IBMC [17], [18].…”

Model Predictive Control for Indirect Boost Matrix Converter Based on Virtual Synchronous Generator

Indirect boost matrix converter is potentially a great alternative to a back-to-back converter for permanent magnet synchronous generators based distributed generation since it can achieve a voltage-boost functionality without utilizing a bulky DC-link capacitor. Despite the success of the indirect boost matrix converter topology, there still exist some issues in the relevant control structure that must be resolved appropriately. First, the existing controls are grid-following controls, which is incapable of islanded operation. Secondly, the exiting controls generate a highly distorted current waveform, which needs to be suppressed by a passive damping resistor. Moreover, without an energy storage element, the distributed generations have no short-time power reserve unit for providing an inertial power to support the utility. In order to solve these issues, a novel approach based on a modified virtual synchronous control and a finite control set model predictive control scheme is proposed in this paper. The former is adopted to ensure proper operations in both grid-connected and islanded modes and to emulate the virtual inertial response by drawing inertial power from the input source. The latter utilizes multi-controls of real-time variables to avoid complicated coupling between the input side and the output side controls and to grant the indirect boost matrix converter with the capability of providing active filter resonance damping. Comparative studies between the proposed control and its existing counterpart are conducted with several simulations in PSCAD/EMTDC software to demonstrate the superior performances of the proposed strategy. Finally, the proposed control is verified in a scale-down experiment testbed.
