Hardware-in-Loop Real-Time Test Bed for Microgrid Systems with Multi-Level Control

Inhalt:
Power electronic application fields have been broadened from single power supply to more and more complicated systems like smart grid interfaced with different kinds of power electronic converters because of continued evolution of renewable energy technology, which brings about great challenges to build a flexible physical platform that could adapt to test different power electronic systems in smart grid. This paper presents a hardware-in-loop real-time test bed for microgrids consisting of multi-distributed generators, local loads, batteries and control system with multi-level control technology. By taking advantages of hardware-in-the-loop real-time simulation system, such as flexibility, fast, safety, low cost, the platform established in this paper can be used in the flexible characteristics exploring and performance evaluation of microgrids in future smart grid.
