Abstract & Overview
Large-scale wind power integration has exerted negative influence on the power system,because of the intermittency and anti-peak-regulation of wind power.A rational wind power casting theory is presented.Firstly,the paper proves its necessity and feasibility from the viewpoint of anti-peak-regulation,then utilizes weibull distribution to fit equivalent load curve,and quantifies the relationship among casting wind power,peak-regulation improvement and wind power generation capacity.Taking the Gansu and Shang-Gan-Ning power system as example,the results show that by way of wind power generation capacity casting,the peak-regulation of system can be improved,and the conclusion can provide scientific basis for the power system dispatchers.
