Emulating Rotational Inertia of Synchronous Machines by a New Control Technique in Grid-Interactive Converters

Abstract: Integration of renewable energy sources (RESs) into power systems is growing due to eco-friendly concerns and ever-increasing electricity demand. Voltage source converters (VSCs) are the main interface between RESs and power grids, which have neither rotational inertia nor damping characteristics. Lack of these metrics make the power grid sensitive to frequency disturbances and thereby under frequency, to load shedding activation or even large-scale collapse. In this regard, the contribution of this pa… Show more

“…The VIC encompasses the fast response power electronic converter associated with the low-inertia constant, producing the inertia power to the power system by the BESS. Therefore, with the VIC control topology, modern grids have allowed the high penetration of the RESs/DGs installations, and the frequency stability has been improved with a superior performance [36,40,[56][57][58][59][60][61]. The conventional virtual inertia control was based on the swing equation of the synchronous machine that the virtual inertia power produced by the VIC can be described as:…”

“…The main problem of this method is that the derivative term in the control structure introduces noise to the system, leading to the unstable operation of the converter. The concept of distributed virtual inertia is presented in [11], [12] for gridfollowing converters in which the energy stored in the dc-link capacitor is used for frequency support. However, the virtual inertia in this method is limited based on some parameters of the converter.…”

“…The grid-forming approach has the benefit of not requiring Phase Locked Loop (PLL) for synchronization, which in many cases improves the stability of the system [5]. Furthermore, grid-forming VSG usually utilizes swing equation to emulate SG, whereas grid-following can be built on top of vector control [6]. Such algorithms can be called Rate of Change of Frequency VSG [5].…”
