Robust Controller Design for a Virtual Synchronous Generator (VSG) Using Linear Matrix Inequalities

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
A new method to design a robust controller for multi-input multi-output (MIMO) systems is presented in this paper. A constant pre-compensator is calculated by solving a set of linear matrix inequalities (LMI) to damp the effect of non-diagonal terms and reduce the effect of interactions in MIMO systems.

Impact of Virtual Synchronous Generator (VSG) on Sub Synchronous Control Interaction (SSCI) in DFIG Systems Using Sequence Domain Impedance Method

2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020
Wind energy, as a promising renewable and clean energy resource, has caused problems including power quality issues and electromagnetically oscillations such as sub-synchronous resonance. Virtual synchronous generator (VSG) has been proposed as a solution to improve dynamic frequency stability in wind turbines, but its impact on the risk of sub ...

Review on virtual synchronous generator (VSG) for enhancing performance of microgrid

2018 International Conference on Power, Signals, Control and Computation (EPSCICON), 2018
Increasing penetration level of Distributed Generators (DGs)/ Renewable energy sources (RES) creates low inertia problems, damping effect on grid dynamic performance and stability. Voltage rise by reverse power from PV generations, excessive supply of electricity in the grid due to full generation of the DGs, power fluctuations due to variable nature ...

Microgrid Control Strategy Based on Battery Energy Storage System-Virtual Synchronous Generator (BESS-VSG)

2020 IEEE Kansas Power and Energy Conference (KPEC), 2020
With more and more renewable energy resources integrated into the power grid, the system is losing inertia because power electronics-based generators do not provide natural inertia. The low inertia will cause the microgrid to be more sensitive to disturbance and thus a small load change may result in a severe deviation in frequency.
