Development of Controller HIL Test-bed for Solar-battery integration

Hardware-in-Loop (HIL) simulation plays an important role in distributed energy resource (DER) systems design, analysis and development. These DER-based systems utilize interfacing power electronic converter units with primary controllers, connected to the distribution network. Before commissioning these DER units, the performance of each of the converters and control system needs validation both independently as well as in microgrid scenario. In such a situation, Controller HIL based simulation and analysis enables validation of control without need for actual plant hardware development. In addition, this approach accelerates system development time, and also enable ease of portability of the developed control algorithms from testing to implementation phase. In this work, a digital-signal-processor based CHIL test-bed for solar-storage integration has been presented using Typhoon 402 HIL Platform. The design of the power electronic system, interface to digital controller, and its performance has been shown with respect to case studies.
