“…However, a current-controlled synchronverter is the same as a current source, providing voltage and frequency support for the system. In [15], a voltage-controlled synchronverter technique is proposed to alleviate the shortcomings of the current-controlled synchronverter. The goal of voltage-controlled synchronverter techniques is to simulate the rotor inertia and system frequency modulation characteristics of SG in frequency control to improve the system's frequency stability [16].…”

“…At present, most scholars seldom present the grid-connection stability and mostly use the small-signal model. Researchers [15] have discussed the smallsignal model adopted to study the stability of a single machine incorporated into the power grid. Some [16] studied the situation of two machines connected to a microgrid under small-signal interference and also studied the influence of the change in the control parameters and circuit parameters on the stability of the system.…”

To reduce the allocation of energy storage capacity in wind farms and improve economic benefits, this study is focused on the virtual synchronous generator (synchronverter) technology. A system accompanied by wind power, energy storage, a synchronous generator and load is presented in detail. A brief description of the virtual synchronous generator control strategy is given. The capacity allocation is based on different optimization goals and the optimal energy storage capacity configuration of the coordinated frequency modulation (FM) control strategy. The detail of the dual-loop control strategy is carried out by establishing the grid-connected transfer function model of the synchronverter energy storage and a theoretical model of life cycle cost is established. The optimal control strategy of coordinated FM for wind storage is implemented using MATLAB software. The simulation showed that the proposed strategy provided the energy storage capacity at high wind speed, which is configured to be 5.9% of the installed capacity of the wind turbine, marking a reduction of 26% compared with the 8% capacity required for independent support. In addition, the proposed method has improved the energy storage capacity configuration of the coordinated FM control strategy.

“…Conclusively, the FCS-MPC scheme's benefits are presented, including simple implementation, straightforward control law, and fast dynamic response. The conventional FCS-MPC-based DG system, however, has been designed for a system with simple inductive filters (L filters) or inductive 335 capacitance filters (LC filters), e.g., presented in [13]- [14]. On the other hand, to achieve sinusoidal grid currents with low distortions, an LCL filter is an attractive alternative with relatively lower cost compared with conventional LC filters [16]- [17].…”

“…Recently, several active damping solutions based on multivariable control for grid-connected rectifiers have been proposed [22]- [24]. The concept of FCS-MPC-based multivariable control can also be applied to grid-connected voltage source inverters (VSIs), as suggested in [13]- [15]. Nevertheless, in the referred works, the purpose of a filter current control inclusion was to achieve overcurrent prevention.…”

Despite its advantages, the LCL filter can significantly distort the grid current and constitute a substantially more complex control issue for the grid-connected distributed generators (DGs). This paper presents an active damping approach to deal with the LCL filter's oscillation for the finite-control-set model predictive control (FCS-MPC)-three-phase voltage source inverters (VSIs)-based DG. The new approaches use the multivariable control of the inverter side's filter current and capacitor voltage to suppress the LCL filter resonance. The proposed method has been tested in steady-state and under grid voltage disturbances. The comparative study was also conducted with the existing virtual resistance active damping approaches for an FCS-MPC algorithm. The study validates the developed control schemes' superior performance and shows its ability to eliminate lower-order grid current harmonics and decrease sensitivity to grid voltage distortion.
