In this paper, a synchronous frame control for a voltage sag/swell compensator utilizing single-phase matrix converter is proposed. First, the configuration of the proposed system and its operation are described. Next, the effects of the degree of voltage sag and load variation on the system stability are analyzed using the transfer function. Finally, the experimental waveforms of the system with the proposed synchronous frame control are compared with those of the system with a stationary frame control. The results demonstrate that the proposed synchronous frame control can suppress the steady state error and pulsation caused by the LC filter resonance better than the stationary frame control.

“…In earlier researches on VSG control, control methods are designed for energy storages rather than DGs [34]- [36], [46], [47], to make the energy storages behave as dedicated frequency compensators. Recent years, various approaches of VSG control for DGs have been developed [37], [38], [43]- [45]. In these approaches, it is usually necessary to calculate complete SG models, which makes the algorithm complicated and therefore requires higher processor capacity.…”

In recent researches on inverter-based distributed generators, disadvantages of traditional grid-connected current control, such as no grid-forming ability and lack of inertia, have been pointed out. As a result, novel control methods like droop control and virtual synchronous generator (VSG) have been proposed. In both methods, droop characteristics are used to control active and reactive power, and the only difference between them is that VSG has virtual inertia with the emulation of swing equation, whereas droop control has no inertia. In this paper, dynamic characteristics of both control methods are studied, in both stand-alone mode and synchronousgenerator(SG)-connected mode, to understand the differences caused by swing equation. Small-signal models are built to compare transient responses of frequency during a small loading transition, and state-space models are built to analyze oscillation of output active power. Effects of delays in both controls are also studied, and an inertial droop control method is proposed based on the comparison. The results are verified by simulations and experiments. It is suggested that VSG control and proposed inertial droop control inherits the advantages of droop control, and in addition, provides inertia support for the system.

“…In the virtual synchronous generator (VSG) control, the controller solves the swing equation in each control cycle to emulate the virtual inertia. Kawasaki Heavy Industries (KHI) project group developed the VSG control in the d − q frame for three-phase and single-phase inverter, respectively [31,32]. Small signal modelling and parameter sensitivity analysis are car-ried out for a virtual synchronous machine, to observe the effect of different parameters on eigenvalues of the system [26].…”

The modern power system is progressing from a centralised generation having synchronous generators to the distributed generation having the large-scale integration of renewable energy sources. These renewable energy sources are interfaced with the system through the inverter. Due to the inertia-less nature of inverter, the system becomes prone to frequency instability. The virtual synchronous generator control is used to enhance the frequency stability by introducing virtual inertia in the inverter control. The virtual synchronous generator technique provides flexibility to the researchers to regulate swing equation parameters in real-time. Based on this concept, this paper proposes an autoregulated inertia control as the first contribution to improve the damping effect of virtual synchronous generator control. In the literature, the primary focus is on the inertia control and negligible importance is given to the damping factor control. Therefore, to show the effect of dynamic damping factor, together with dynamic virtual inertia, on the transient stability; an auto-regulated inertia and damping factor control of virtual synchronous generator is proposed as the second contribution. Simulation results of the proposed techniques are compared with the various virtual inertia control techniques in the real-time digital simulator environment. The results show that auto-regulated inertia and damping factor control is the most effective method to provide dynamic frequency support to the microgrid.
