Should energy storage be combined with Modular Multilevel Converter (MMC)?

Therefore, it is necessary to combine energy storage with modular multilevel converter (MMC) to fluctuate power suppression and use virtual synchronous generator (VSG) control instead of vector control to improve its support ability for the grid [4, 5].

How is grid inertia maintained?

Grid inertia is maintained by the kinetic energy produced or absorbed by the rotor’s mass, as shown in the following equation . where Ekin represents the kinetic energy, ωr the rated velocity of the rotor, and J the moment of inertia. However, the penetration of RESs reduces the inertia in the power grid.

Do inverter-based grids need more inertia?

A grid with slower generators needs more inertia to maintain reliability than a grid that can respond quickly,” the report says. One of the key takeaways from the report is that inverter-based resources have the ability to quickly detect frequency deviations and respond to system imbalances using power electronics.
