Grid-connected power frequency inverter

Essentially, a grid-following inverter works as a current source that synchronizes its output with the grid voltage and frequency and injects or absorbs active or reactive power by controlling its output current.

Flywheel energy storage frequency and power

In the 1950s, flywheel-powered buses, known as , were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have a greater capacity. It is hoped that flywheel systems can replace conventional chemical batteries for mobile applications, such as for electric vehicles. Proposed flywh. FESSs have high energy density, durability, and can be cycled frequently without impacting performance. Therefore, the FESS is suitable for delivering high power and low energy content to the grid. These traits make it ideal for supporting short term frequency regulation in power systems.
