Integrating renewable energy sources into grids
Droop coefficient placements for grid-side energy storage …
We regard all energy storage as ideal grid-following devices and ignore their direct contribution to nodal frequencies. The energy storage usually has less impact on nodal frequencies than conventional units in HVDC receiver-side power grids. Our current method supports considering both droop and inertia in the energy storage model.
