Abstract: An energy storage and modulating system for renewable energy off-grid power generation, and a method for modulating the same. The excess electricity from a renewable energy power generation device after the electricity consumption on a demand-side is met is output to a short-term energy storage device and/or an electric energy conversion device to be converted into a combustion medium corresponding to a mid/long term energy storage device.
