| 摘 要： | 风力发电已经成为清洁能源中发展最快的一种发电方式,确定风电穿透功率极限对风电并网的规划和运行有着重要作用。文中提出了基于直流概率潮流的风电穿透功率极限计算方法,计算中通过直流概率潮流计算,综合考虑风电场出力、发电机出力、节点负荷等因素的随机性,得到含有风电场的电力系统中线路有功潮流的概率分布,然后利用随机规划理论和改进的遗传算法求解风电穿透功率极限。最后以IEEE30系统为算例,验证计算方法的有效性。

| Abstract: | Among renewable sources of energy, wind power is becoming the fastest growing form of electricity generation. It is of great importance for the planning and operation of wind farm to calculate the wind power penetration limit. This paper proposes an approach to calculate the wind power penetration limit based on DC probabilistic load flow computation. First, it analyzes the influence introduced by wind farm to the load flow of the power syste. After that, it builds a model to solve the wind power penetration limit by stochastic programming and genetic algorithm. Then results on IEEE30 system validate the proposed approach. |
