The invention provides a planned annual electric power balancing method taking wind power output characteristics into consideration, which comprises the steps of: counting installed capacity and output of a launched wind power plant at a system maximum load moment, calculating an output percentage of the launched wind power plant at the system maximum load moment, calculating an output percentage mean value of the launched wind power plant at the system maximum load moment, finding out a correlation wind power plant, calculating wind power output correlation coefficient, calculating an output percentage of a planned wind power plant at a planned annual system maximum load moment, calculating output of the planned wind power plant at the planned annual system maximum load moment and acquiring total output of the wind power plants in the planned annual region to obtain a regional electric power profit and loss equation, judging electric power balance according to the equation and the like. The planned annual electric power balancing method takes wind power output at the planned annual system maximum load moment into consideration, makes electric power balancing results more objective and real, and provides guidance for electric power system planning.
