摘要

METHOD FOR THE CONTROL OF POWER RAMP-RATES MINIMIZING ENERGY STORAGE REQUIREMENTS IN INTERMITTENT POWER GENERATION PLANTS 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 10 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. soc PV GC BSAT ESAT rror -o *- ,ero + Ramp-rate (rmax) + I SOCtar -1 BAT EBAT error + Ramp-rate (rma) ++ EBAT, ref calculation SOCtar calcuation calculation Location PVplant - Clear Sky Date model Irradiance mode Linke Turbidity
