Power quality analysis of wind-storage combined system connected to power grid

With the continuous connection of large-scale wind farms and the wide application of energy storage, the power quality problems have attracted more and more attention. This paper proposes calculation methods and steps for the power quality index caused by the integration of the wind-storage combined system into the power grid. According to an example of a wind-storage system, combined with technical parameters of devices, the analysis and calculation program ETAP is used to analyze and evaluate the power quality problems.
