Title: METHOD FOR CONTROLLING POWER FLUCTUATION RAMPS HAVING ENERGY STORAGE SYSTEMS IN PLANTS FOR INTERMITTENT ENERGY GENERATION
Abstract:
The invention falls within the technical field associated with methods for controlling power fluctuation ramps using energy storage systems in plants for intermittent energy generation, wherein said method reduces the size of the energy storage system necessary to fulfill the requirement of a maximum power fluctuation ramp, by means of a step of imposing a maximum power variation ramp by imposing the dynamic component of the ramp, defined as the gradient according to which the power of the plant is varied in each control cycle in accordance with the state of charge of the energy storage system (SOC).
