Microgrid Virtual Synchronous Generator

How can virtual synchronous generators improve the stability of a grid?

A solution towards stability improvement of such a grid is to provide virtual inertia by virtual synchronous generators (VSGs) that can be established by using short term energy storage together with a power inverter and a proper control mechanism. Several schemes of VSGs and its applications are reviewed in this chapter. 12.1.

Can a virtual synchronous machine synchronize a microgrid?

With a virtual synchronous machine, the weak grid properties are researched and modeled. To connect the ESS to the grid, an inverter model is designed, as well as a dual second-order generic integrator PLL that can synchronize the system in inaccurate and imbalanced situations. A novel method for estimating the microgrid’s frequency is described.
