Energy storage vsg full name

What is a virtual synchronous generator (VSG)?

To improve the inertia and primary frequency regulation ability of the grid, the virtual synchronous generator (VSG) control scheme was introduced into the energy storage grid-connected controller, enabling it to simulate the behavior of SGs by injecting balanced energy at the appropriate time.

What does VSG stand for?

Why is VSG important in a power grid?

The penetration of power electronic-based power generation in power grid reduces the total inertia, and thus increases the risk of frequency instability when disturbance occurs in the grid. VSG produces virtual inertia by injecting appropriate active power value to the grid when needed.

What types of energy storage can be used for VSG application?

Various types of energy storage could be used for VSG application such as in the form of flywheel, capacitor and battery-based storage. Different types of energy storages would have different charging and discharging rates. VSG with flywheel-based storage helps in regulating the active power output following frequency deviation.

How effective is VSG in supplying synthetic inertia?

Meanwhile, the application of VSG with energy capacitor storage (ECS) system helps in smoothening the line power fluctuation caused by variable wind speed permanent-magnet synchronous generators. Hence, the type of energy storage used will play a significant role in the effectiveness of VSG in supplying synthetic inertia in the grid.

What is the function of VSG in MG?

An MG is a small-scale power grid that consists of a few energy resources and loads. Most of the energy sources are RES, which causes low inertia in the MG. The function of VSG in MG is to perform initial regulation of active power and reactive power during initial load disturbances and renewable energy intermittent.
