Abstract :
A microsource interface with energy storage would help to realise the plug and play functionality of a MicroGrid. This paper discusses the energy storage interface. Selection and sizing of the energy storage unit is explained. A bi-directional converter is used to interface the storage, and a controller is implemented to keep the output voltage of the converter approximately constant. The energy storage unit was connected to a PV system in simulation. The system response to the irradiance, temperature and load variations were analysed in this paper.
