Abstract:

随着风电的大量开发，大规模风电接入电网的网损问题日益凸显出来。首先，本文构建了一个有大规模风电接入的输电系统模型，结合电网实际条件，筛选出风电接入下的网损影响因子；然后，从网损计算公式出发，对电力系统模型及网损表达式进行化简，确定了荷–网–源协调降损的方法；最后，以大规模风电接入的甘肃电网为背景，通过仿真分析，验证了电网降损控制方法的正确性。
With the development of wind power, loss problems of large-scale wind power grid become in-creasingly prominent. First, combined with the actual grid conditions, we establish a model of large-scale wind power transmission system and select the main loss factors of the wind power. Then, starting from the loss formula, we simplify the power system model and loss expression, and fix the load-network-source coordination methods for reducing loss. Finally, we do some simulations to verify the correctness of power control method for reducing loss with the Gansu power grid as the background.
