VSG is a combination of control algorithms, renewable energy sources, energy storage systems, and power electronics that emulates the inertia of a conventional power system . VSG algorithm is the primary part of the system which interfaced among different storage units, generation units and the utility grid.
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.
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.
The grid connected inverters, which mimic the steady-state and transient characteristics of SG, are called VSGs (virtual synchronous generators). It is predicted that VSG integrated systems will be the future of power system network , , .
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.
Owing to the importance of VSG in the modern power grid, this study provides a comprehensive review on the control and coordination of VSG toward grid stabilisation in terms of frequency, voltage and oscillation damping during inertia response. A review on the type of energy storage system used for VSG and their benefits is also presented.
