Power Systems Performance Evaluation on High Renewable Penetration Levels

Abstract

The paper proposes a novel approach for system performance measurement and evaluation on asynchronous generation high penetration levels scenarios. The concept of the Multi-Infeed Interaction Short Circuit Ratio (MISCR) is extended for multiple asynchronous sources. Different scenarios combining wind power penetration levels and capability factors are analyzed, considering the IEEE benchmark 39-Bus system modified and a simplified full converter (FC) wind generation model. The results suggests that the traditional approaches from the Short Circuit Ratio (SCR) be more conservative than the proposed methodology.
