Experimental Validation of High Performance HIL-based Real-time PMU Model for WAMS

Abstract

This paper presents design, analysis, and implementation of a new real-time hardware-in-the-loop (HIL) based model for synchronized phasor measurement unit (PMU) compliant with the standard C37.118.1. The proposed model is feasible for a wide area measurement system (WAMS) in modern power grids involving renewable energy sources. The main goal is to investigate the performance of the HIL-based PMU models, each of which represent an intelligent agent. Accordingly, monitoring, control, and protection functionalities are significantly enhanced. Additionally, the proposed model is tested for steady-state (normal) and dynamic (fault occurrence) performance through different scenarios. The proposed HIL-based PMU model performance is investigated and compared with measurement (M) and performance (P) class models. Furthermore, a reduced-scale 6-bus real-time experimental laboratory setup incorporating digital controller is built and tested to demonstrate the practical validity of the proposed model for smart grid research and development.
