Wind power generation is a relatively mature power generation technology of renewable energy, it is difficult for the power sector to predict wind power, because of inherent randomness and intermittency of wind power. The uncertainty of wind power brings great challenges to the economic dispatch of power system, how to make the most use of wind power resources and minimize the influence of wind power uncertainty on the power supply side is a problem that economic dispatch needs to solve. This paper proposes a robust dispatch model, which include wind power and with the goal of the lowest power generation cost, the model considers automatic generation control (AGC) unit adjustment in response to uncertain fluctuations, and maintain power balance of the system. Then uses simulation scenes, analyze security and economy of the robust dispatch method.
