A System Emulator for AC Microgrid Testing

摘要: The control algorithms proposed to improve load sharing, stability, and power quality in microgrids need rigorous testing. Real-time emulation is one of the proven approaches provide realistic testing environments for development products algorithms. Typically, microgrid system-level testing, individual component-level (source or load) emulators are employed: hardware test bed clusters. These use multiple converters, increasing complexity consuming space. In this article, we propose a flexible system emulator , based on single converter complete microgrid, at any node selected by user. This unlike case literature till date, which large number converters emulate dynamics, wherein each used mimic behavior particular component, such as source load. modeling aspects discussed, accuracy model developed working established through simulations experiments laboratory prototype, respectively, considering simple two-distributed-generator-based various scenarios.
