A calculation method for power system peak regulation suitable for wind power output

Abstract

The invention relates to an electric system peak regulation calculation method suitable for wind power output. The method is characterized by sequentially comprising the steps that step1, certain n days are selected, and according to wind power output and typical daily loads of the n days, Pearson's correlation coefficients, from r1 to rn, of wind power output data and the typical daily loads of the n days are calculated; step2, according to the calculated Pearson's correlation coefficients from r1 to rn, the minimum Pearson's correlation coefficient ru is selected, and wind power output of the u day is determined as the most obvious typical scene in inverse regulation; step3, the typical scene is subtracted from the typical daily load of the day of the most obvious typical scene in inverse regulation, equivalent load values are obtained through calculation, and the minimum equivalent load value is subtracted from the maximum equivalent load value to obtain the peak-regulation capacity of a power grid. The standby capacity of a wind power plant can be reasonably arranged, and the complex degree of the peak-regulation capacity of the wind power plant is greatly lowered.

Description

technical field [0001] The invention relates to the field of power system scheduling automation, in particular to a power system peak regulation calculation method suitable for wind power output. Background technique [0002] Wind power generation is currently the most mature energy utilization method with the greatest prospects for large-scale development and commercialization among renewable energy development technologies in the world. Compared with traditional power generation methods, the most fundamental difference of wind power generation lies in the randomness, intermittency and uncontrollability of its active output. This characteristic determines that the peak-shaving capability of the power grid must be considered when wind power is connected to the grid. At present, in the planning of large-scale wind power grid integration, the method of applying the scenario method to the economic dispatch of the power system is: collecting wind power data over the years to obt...
