ETAP-based Power Quality Assessment of Energy Storage Stations Connected to Grid

In recent years, energy storage systems have become crucial components in the development of advanced power systems. But their integration with the grid can lead to power quality issues due to nonlinear electronic switching devices, diverse operating states, extreme conditions, and frequent adjustments of active power, etc. To address these challenges, this paper proposes models and methodologies for power quality assessment. ETAP software is utilized for simulation to assess and analyze power quality issues and generating report. A case study is conducted using ETAP to evaluate the power quality of a specific energy storage station. The assessment includes voltage deviations, voltage fluctuations, flicker, and harmonic analysis. Based on the evaluation results, recommendations for improving power quality are provided.
