Effects of high penetration of renewables in power grid synchronization and frequency fluctuations

Trabajo presentado en el International Symposium “Topical Problems of Nonlinear Wave Physics” (NWP-2021), celebrado en Nizhny Novgorod (Rusia) del 19 al 22 de septiembre de 2021.We study power grid stability and frequency fluctuations in future scenarios characterized by a high share of wind generation in the power grid. We propose a dynamical model that includes both conventional and variable renewable generation, as well as demand variations, and it can reproduce the statistical properties of actual frequency fluctuations. With this model, which we apply to the power grid of Gran Canaria island as a case study, we characterize the frequency fluctuations with high penetration of wind power and propose a method to estimate the amount of control needed to keep frequency fluctuations within statutory limits.Peer reviewe
