With the rapid development of new energy power generation, large-scale wind power generation has been integrated intopower grids. However, the fluctuation and discontinuity of wind power have introduced challenges to the safe and reliableoperation of power systems. Therefore, constructing a reasonable dispatching method considering the uncertainty of windpower output has become an important topic. This study aims to establish a reasonable power system dispatching optimizationmethod considering the uncertainty of wind power output. Hence, an ellipsoidal robust set of wind power outputwas initially constructed in accordance with the predicted value and predicted error of wind power. Second, a power systemoptimization dispatch model of automatic generation control (AGC) was established on the basis of the robust set. This modelaimed to minimize the cost of power generation and maximize the use of wind power according to the following constraintconditions: power system power balance, upper and lower limit of wind and thermal power unit outputs, climbing power, andspinning reserve. Finally, the internal point method was employed to solve the example. Results show that on the premiseof safe operation, the total operating cost of the robust optimization dispatch method is decreased by 8.64% compared withthat of the traditional dispatch method, and the economic efficiency is improved. The robust optimal dispatch considers theuncertainty of wind power output, and load shedding scene seldom occurs, thereby enhancing the operational reliability. Thisstudy can improve the reliability and economics of power system operation and provide a basis for optimization dispatch ofpower systems.
