Background: The growing penetration of intermittent renewable energy in power grids (such as solar and wind) is causing instabilities in the electrical network. Stabilising power grids with renewable sources is needed. Technology Description: The electric spring has been developed to facilitate the adoption of intermittent renewable energies by improving the voltage/frequency stability across the grid. The electric spring will allow a greater proportion of our energy to come from renewable sources. Applications: Stabilising power grids with intermittent energy sources.
1) Increases stability of power grids with intermittent power sources 2) Facilitates the use of renewable energy
