Robust Virtual Inertia Control of a Low Inertia Microgrid Considering Frequency Measurement Effects [PDF]
IEEE Access, 2019 Virtual inertia emulation could be regarded as an inevitable component of microgrids with renewable energy, enhancing microgrid inertia and damping properties. In applying this control technique, a phase-locked loop (PLL) is necessary to obtain the estimation of the system frequency data.

Virtual Inertia Control Strategy in Microgrid Based on Virtual Synchronous Generator Technology
IEEE Access, 2018 Although the virtual inertia algorithm can be used to enhance the inertia of microgrid system, the strong coupling and low precision always limit its popularization and application. Therefore, a novel virtual inertia control strategy is proposed in this paper.

A Virtual Inertia Control Strategy for DC Microgrids Analogized With Virtual Synchronous Machines [PDF]
IEEE Transactions on Industrial Electronics, 2017 In a DC microgrid (DC-MG), the dc bus voltage is vulnerable to power fluctuation derived from the intermittent distributed energy or local loads variation. In this paper, a virtual inertia control strategy for DC-MG through bidirectional grid-connected converters (BGCs) analogized with virtual synchronous machine (VSM) is proposed to enhance the ...

Enhanced Virtual Inertia Controller for Microgrid Applications
Energies, 2023 Unlike Synchronous Generators (SGs), Virtual Synchronous Generators (VSGs) inertia is not fixed once it is manufactured and only has an upper limit defined by its energy storage components. In this paper, a novel Enhanced Virtual Inertia Controller (EVIC) is proposed.

Virtual Synchronous Generator Using an Intelligent Controller for Virtual Inertia Estimation [PDF]
Electronics, 2021 Virtual synchronous generators (VSGs) with inertia characteristics are generally adopted for the control of distributed generators (DGs) in order to mimic a synchronous generator. However, since the amount of virtual inertia in VSG control is usually constant and given by trial and error, the real power and frequency oscillations of a battery energy ...

Dynamic Virtual Inertia and Damping Control for Zero-Inertia Grids
CoRRIn this paper virtual synchronous generation (VSG) approach is investigated in application to low- and zero-inertia grids operated by grid-forming (GFM) inverters. The key idea here is to introduce dynamic inertia and damping constants in order to keep power gird stable during different types of faults, islanding or large power balance oscillations. In
