【 摘 要 】

This paper proposes a Cloud Energy Management System (C-EMS) for the building-scale hybrid microgrid. The building-scale hybrid microgrid is composed of renewable energy generators, charging piles, dc and ac loads, a diesel generator, energy storage devices, and a power electronic transformer connected to the ac power grid. The C-EMS is in charging of them. With the management of C-EMS, for the power system, the building-scale hybrid microgrid can be considered as a four-quadrant controllable node, which means it can be controlled to either generate or consume reactive and active power to the power system. In addition, based on wireless communication, the C-EMS receives the command of cloud management centre and make the microgrid operate at the assigned power. Therefore, numerous C-EMS can be managed via the cloud manage centre, which improves the controllability of the power system. The proposed C-EMS has been verified by the simulations carried out in Matlab/Simulink.
