摘要
随着能源危机的日益临近和电力电子器件技术的大幅进步与应用,风电场经VSC-HVDC并网已经变成了一种可能。相对于其他诸如火力发电和水利发电等传统发电方式,风力发电不能够控制能量的注入与供给,所以风力发电的输出稳定与否主要取决于风速的变化。建立了风电场等效聚合模型和柔性直流输电(VSC-HVDC)的详细模型。为了平抑风电并网时风电场的功率波动,分别采用了单纯形法和遗传算法对柔性直流输电的控制器进行了优化,优化结果显示,两种优化方法均能平抑风电场的输出功率波动。
As energy crisis has draws more and more attention all around the world,wind energy is getting more and more important as a kind of renewable and clean energy. The output of the wind energy,however,is subjected to changes of wind speed,thus,the wind farm output often fluctuates. This paper builds the aggregate wind farm model and the VSC-HVDC model. In order to stabilize the fluctuation of the wind farm output,the paper adopts the Simplex Method and Genetic Algorithm respectively to optimize the controller of VSC-HVDC.The result shows that both of these two different ways help to constrain the fluctuation of the output of the wind farm and have strong engineering application value.
