Analysis on Capacity of Wind Power Integration into Grid Based on Power Balance

Abstract:

Among all the factors influencing the capacity of wind power, peak regulation capability is commonly regarded as one of the most important constraint factors. From the perspective of peak regulation, the maximum peak-load regulating adequacy revised by the wind power characteristic coefficient is the limitation of the capacity of wind power. This paper proposes an assessment system on capacity of wind power integration into grid based on power balance. First of all, this assessment system takes the impact of wind power integration on the reserve capacity of the power system into consideration. Then calculate the reserve capacity based on power generation reliability index. Finally, evaluate the capacity of wind power based on the peak regulation capability of the units during the low load period. This paper analyses the capacity of wind power integration into Liaoning power grid based on power supply characteristics, load characteristics and peak-valley difference, and points out that the phenomenon of the “wind curtailment” is unavoidable. According to the specific situation of wind power limitation, this paper proposes measures to maximize the capacity of wind power.
