Design and Implementation of Energy Hub for Smart Grid

In this paper a design and implementation method of smart energy hub is presented. This energy hub can incorporate diversified renewable energy, automated and intelligent management. The design of it deeply considered on the use of renewable energy and the reliability of power supply for critical load. It can be used as a basic unit of smart distribution grid, and it designs to operate in both gridconnected and stand-alone modes. The prototype of energy hub is developed and experiments are carried out. The experimental result show that the energy hub achieves the design features and operates stable and reliable.
