The invention discloses a wind power penetration limit determination method based on peak-regulating balance constraint. The method comprises: firstly, solving wind power penetration limit of each selected time-in-point in a time interval [ton, toff], on each time-in-point, using a discrete variable search algorithm to perform maximum search on UGt, searching a generator set state vector UGt in a generator set state space [omega], the generator set state vector UGt making wind power capacity an electric system can accept reach the maximum in the time-in-point, and through a wind power penetration limit model to calculate the wind power penetration limit value at the moment; and performing minimum search on the wind power penetration limit values obtained in all time-in-points, to obtain the minimum value of wind power penetration limit in the interval of [ton, toff]. The method uses time combining with the generator set as decision variables, and an improved bender's decoupling algorithm is used for solution and optimization, preventing influence on calculation precision by selection of operating methods of an electric system and setting of original values. The method can improve precision and efficiency of wind power penetration limit calculation.
