本文提出了一种风力发电与抽水蓄能发电相结合的系统稳定电力的方法。该系统根据风电场的输出预测值运行。当测量到的风电场输出大于预测值时，系统就会用剩余的电力抽水。当风电场输出小于预测值时，系统由水轮发电机补充系统的缺电。此外，由于水轮发电机工作在一个启动延迟时间，此时会出现输出短缺。为了改善当时的产出短缺情况，我们利用统计模型来估计低于预测值的时间。结果表明，该系统成功地稳定了水轮发电机的功率，提高了水轮发电机的启动延迟时间。
In this paper, a method of stabilizing electric power by a system which is a combination of wind power generation and pumped storage power generation is proposed. The system operates based on the output predicted value of the windfarm. When the measured windfarm output is larger than the predicted value, the system is pumping up water with surplus power. When the windfarm output is smaller than the predicted value, the system is filling up lack power by hydro generator. Also, since hydro generator works with a start-up delay time, output shortage occurs at this time. To improve output shortage at the time, we estimate the time below the predicted value by a statistical model. As the result, the system succeeded in stabilizing the power and improving the start-up delay time of the hydro generator.
