ABSTRACT:
With the growing integration of renewable energy sources, the performance and reliability of grid-connected inverters are increasingly vital to maintaining power system stability. Controller Hardware-in-the-Loop (CHIL) testing has emerged as a powerful technique for validating and enhancing inverter control systems in real-time, effectively bridging the gap between software simulation and field deployment. This presentation examines how CHIL testing can be leveraged to optimize inverter performance, refine control strategies, and ensure compliance with evolving grid codes and interconnection standards. Through real-world case studies and detailed test methodologies, we demonstrate the benefits of CHIL-based validation in identifying control challenges, fine-tuning parameters, and verifying dynamic behavior under diverse grid conditions. The findings underscore CHIL as an essential tool for inverter manufacturers and project developers striving to meet stringent utility requirements while minimizing development timelines and deployment risks.
