“…The paper (Duan et al, 2021) proposes an analogous virtual synchronous generator control for multi-port converters with simultaneous implementation of droop, virtual inertia and damping characteristics. The paper (Rathore et al, 2016;Sakaeda et al, 2017) optimizes the inertia constant and virtual virtual coefficient of vsg according to frequency deviation and voltage deviation The paper (Liu and Gong, 2020) analyses the effect of droop-control on the stability in VSC-HVDC transmission systems and verifies the isolation of DC systems from low frequency oscillations through simulation. The above control strategies all play a stable role in the regulation of the system frequency, but the regulation mode is relatively single, it is difficult to cope with a variety of different operating conditions, while the speed and sensitivity of the regulation of the frequency are poor.…”

Compared to conventional DC transmission, Voltage source converter based high voltage direct current transmission (VSC-HVDC) has the advantages of independently controllable transmission power, no commutation failure, no reactive power compensation and low harmonic levels. However, VSC-HVDC transmission cannot provide effective frequency support and regulation for the system after grid connection. For this reason, an adaptive neural fuzzy virtual inertia control method is proposed to impose a control strategy on the converter at the receiving end of a VSC-HVDC transmission. The method uses the frequency change rate and the amount of change of frequency as constraints to dynamically adjust the virtual inertia and damping coefficients. It provides larger inertial support when the frequency fluctuation is large and smaller inertial support when the frequency fluctuation is small, thus adapting to different operating conditions. Finally, a hardware-in-the-loop simulation platform is built. The superiority and application prospect of the proposed strategy in frequency stability of the system are verified by comparing the proposed strategy with the traditional virtual control strategy.

“…The generated current references are fed into the current loop controller. In summary, there are three layers of control for typical VSG control, namely, current control loop, voltage control loop, and droop with VSG dynamics loop [15]. The VSG dynamics can be described by the following equations [16]:…”

Virtual Synchronous Generator (VSG) has been developed in the past few decades to address the problem of transient dynamics, i.e. primary control, virtual inertia. Many researchers use DC voltage sources or neglect MPPT controller in VSG studies. It leaves a research gap whereas the DC voltage source is an infinite source where in solar PV system, the power is limited and affected by MPPT controller. This paper investigates the VSG implementation in single-stage solar energy conversion system (SECS) interconnected to an aggregated weak grid condition. This paper presents a feasible way to implement VSG in a practical application without compromising MPPT performance.

“…Because of the operational flexibility offered by VSM-based control strategies, a wide range of implementations and applications have been proposed [8,[10][11][12][13][14]. Furthermore, auxiliary functions for supporting the power system operation can be integrated in the VSM control framework as discussed in [15][16][17][18]. Several recent studies have also analysed how VSM-based control schemes can be utilised to damp local oscillations in small-scale power systems [15,16,19,20].…”

Two different methods for implementing inertial damping on a Virtual Synchronous Machine (VSM) and their potential for attenuating power system oscillations when utilized in a VSC HVDC terminal are investigated in this paper. As a reference case, the VSM is considered with only a frequency droop providing damping in the virtual swing equation. Then, the effect of damping based on high-pass filtering of the virtual speed is compared to damping based on high-pass filtering of the measured grid frequency. A simplified model of a power system with two equivalent generators and a VSC HVDC terminal is introduced as a case study. Analysis of the small-signal dynamics indicates that damping based on the VSM speed has limited influence on the power system oscillations, while improved attenuation can be obtained by introducing damping based on the locally measured grid frequency. The presented analysis and the operation of the proposed VSM-based damping strategy is validated by numerical simulation of a 150 MVA VSM controlled VSC HVDC terminal connected to a dynamic model of the assumed grid configuration.
