Procedure for supply control and storage of power provided by a renewable energy generation plant

It allows simultaneously providing capacity sale services (e.g. frequency regulation or voltage regulation), energy sale services (energy transfer from off-peak hours to peak hours), and stabilization services of a renewable plant, said process comprising the following stages: determining the values of energy quantity to be produced by the plant during a near future time interval; introducing these values of energy quantity, in the control unit; generating an hourly programme of energy supply to be provided by the energy accumulator unit to the network, and depending on the values of energy to be produced, which: stabilizes the power supplied by the plant to the network; regulates the frequency and the voltage of the network, and transfers the energy between off-peak hours and peak hours, or from hours with saturation of the network to hours without saturation.
