AUTOMATIC POWER REDUCTION CONCEPT FOR RENEWABLE GENERATION SITES

Due to the growing number of renewable generation power plants installed within worldwide power systems both at the level of distribution and transmission networks, grid operation is becoming more and more challenging. Under this context, critical situations with violations of operational restrictions are occurring more and more frequently. To avoid such instances, an automatic power reduction logic could be implemented at the RES (Renewable Energy Sources) generation units level under specific conditions of the network such as N-1 conditions. This paper presents an automatic power reduction concept possible to be considered for renewable power generation power plants based on PTDF (Power Transfer Distribution Factors) computation using SmartFlow/EurostagTM software and a dedicated SCADA (Supervisory control and data acquisition) system to be correlated with the energy management system of the generation site in order to achieve an optimized active power control of the generated power.
