Method for the control of power ramp-rates minimizing energy storage requirements in intermittent power generation plants

摘要

The present invention is a method for the control of power ramp-rates minimizing energy storage requirements in intermittent power generation plants, such as for example a photovoltaic solar plant, which minimizes the energy storage requirements approximately halving the size of storage systems necessary to comply with a maximum allowable ramp-rate given by a grid code regulation regarding the state of the art, reducing thus investment costs in the plant and/or carrying out a rationalized use of the energy storage system, in such a way that in order to achieve the same maximum fluctuation ramp, a minor use is done of the energy storage system, minimizing the losses and extending its working life, and therefore reducing the plant operational costs.
