Decentralised source scheduling in a model nanogrid using DC bus signalling

Abstract Ananogrid is a small DC power system that uses distributed energy sources to power local loads. DC bus signalling, a novel control strategy that schedules sources in a decentralised fashion, brings the non-renewable sources in a nanogrid online when the renewable sources have been exhausted. This paper presents a prototype model nanogrid that uses power electronic converters to interface the sources and loads to the nanogrid. The design of the system is discussed and experimental results are presented. The results show that DC bus signalling allows the sources to be consumed in a prioritised fashion.
