Based on the current development of smart grid, this paper makes an in-depth exploration on the interoperability of microgrid platforms, mainly on the interoperability among institutions. Conduct a hierarchical analysis of different requirements to study different levels of interoperability. In this paper, a private hybrid cloud based SCADA architecture is found based on the interoperability of the microgrid platform while ensuring security limitations. Because data collection and critical monitoring are limited by time in the grid, not as critical monitoring and data collection can be accessed by private cloud partners only after being selected. And the main SCADA function is still controlled by the local server, so the cloud architecture is mixed, and this communication is a service delivery model, a model based on cloud computing.

Aiming to the voltage of the stator side is generated by the modulation of the SSC in the improved topology, especially under the circumstance with the asymm Teric fault of stator side, DFIG's electromagn Teic torque, amplifies ripple of grid-connected power for the grid side. The novel control method suitable to stator side converter and rotor side converter based on reduced-order resonant controller (RORC) is proposed in this paper, DFIG's torque and output power performance are improved. Under the RORC control conditions the transfer functions of stator current and torque control system are established, the amplitude characteristic and the system stability of RORC control are analyzed. The simulation results in Matlab/Simulink verify the correctness and validity of the proposed method.
