Distributed Operation and Control Using Interconnected Nanogrid System

The house automation systems evolution, creates the necessity to define new formalities for their functionalities in order to granulate some criteria's such as autonomous operation. The structure is represented by a set of nanogrid which can work and share resources independently. A nanogrid power system can be considered as small microgrid system and can operate in either Grid Connected mode (GC) or Standalone mode (SA). In this is paper, a management strategy of three domestics nanogrid systems is investigated to achieving locally autonomous operation. Furthermore, a droop control strategy is employed in order to increase the power sharing and to adjust the voltage magnitude. In addition, the power management system and control design are detailed. The effectiveness of the proposed management strategy is exanimated by simulation test and the desired performance is verified.
