Robust Power Decoupling Based on Feedforward Decoupling and Extended State Observers for Virtual Synchronous Generator in Weak Grid

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2023
Virtual synchronous generator (VSG) can provide inertia support for a more renewable-energy-integrated power system. However, there are power couplings between active power and reactive power in a weak grid.

Virtual Impedance Adaptive Study of Parallel Virtual Synchronous Generators

2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019
As the increasing of the capacity of the micro grid, it is difficult for a single VSG-controlled inverter to meet the requirements of micro grid use. VSG operating in parallel has become the main solution, and the problem of equalization in the division has naturally become the focus of research.

Seamless transfer of virtual synchronous generator using virtual synchronizing torque controller

International Journal of Circuit Theory and Applications
AbstractInverter‐dependent renewable energy sources are being integrated into the grid, raising several stability‐related difficulties. This is because these renewable sources have less inertia than synchronous generators. Since the power grid's overall inertia has improved, the introduction of virtual synchronous generators (VSG) has gained much ...

Distributed generation grid integration using virtual synchronous generator with adoptive virtual inertia

2013 IEEE Energy Conversion Congress and Exposition, 2013
Virtual Synchronous Generator (VSG) is a control scheme applied to the inverter of a distributed generating unit in order to support power system stability by imitating the behavior of a synchronous machine. The VSG design of our research incorporates the swing equation of synchronous machine to express a virtual inertia property.
