Synchronous condensers as mentioned in the other grid solves for you, but there's loads of interesting research currently looking into running large scale grids without any synchronous components. https://www.pv-magazine.com/2022/06/08/new-model-for-grid-forming-inverter-operation/ https://www.pv-magazine.com/2022/06/08/new-model-for-grid-fo... Other options include this where they demonstrate that they can switch between synchronous condenser and generator mode. Allowing a Power 2 X plant to provide system stability when it is not needed. > 2011: first synchronous condenser conversion, from a 473 MVA generator to a +360/-210 MVAr synchronous condenser, making it possible to change between generator and synchronous condenser mode, depending on the season; https://www.modernpowersystems.com/features/featurege-synchronous-condensers-100-years-on-7769875/ https://www.modernpowersystems.com/features/featurege-synchr...
