Abstract—Since renewable energies have been and will be massively integrated, electrical power grids require more refined generation dispatch modes and smarter communication methods. In this paper, the real-time generation dispatch and communication architecture of smart grid with renewable energy are studied. Firstly, the technical characteristics and application background of smart grid communication network are introduced. Then, according to the defined candidate model of communication information and the related international standards available to the model, a real-time generation dispatch model, suitable communication method and its simulation environment based on IEC 61850 are established, and adopting them can help to optimize the economical operation point of conventional units and ensure the utility rate of renewable energy. Finally, the proposed generation dispatch model was implemented using MATLAB to estimate the 10 unit test system with a wind farm. From the simulation results, the suitability and availability of the studied generation dispatch model can be proved well.
