摘    要:为了分析风机的不确定性出力对电网运行的影响,建立了风电场的概率模型,利用两点估计法(2PEM)进行概率潮流计算。然后,建立了综合考虑有功网损、电压偏移量和静态电压稳定裕度的多目标无功优化模型,并通过层次分析法(AHP)确定各个目标函数的权重,避免了人为主观臆断性。提出了量子人工蜂群算法,并将该算法和前述的概率潮流计算相结合应用到风电场无功优化当中。最后,以IEEE 14节点系统为例,将风电场接入该系统进行无功优化,并和传统的人工蜂群算法(ABC)进行比较,结果表明量子人工蜂群算法优化效果更好,具有更高的收敛精度,有效地避免了早熟现象。

关 键 词:风电场  概率潮流  两点估计法  多目标无功优化  层次分析法  量子人工蜂群算法

Abstract:In order to analyze the impact of uncertain output of wind driven generators on power grid operation, a probabilistic model of wind farm is established, and the two point estimation method is used for the probabilistic load flow calculation. Then, a multi-objective reactive power optimization model is established, including the network losses, the voltage offset and static voltage stability margin, and the weights are all determined by the AHP algorithm, avoiding the subjective nature. Then the quantum artificial bee colony algorithm (QABC) is proposed, and it is used in the reactive power optimization in wind farm with the probabilistic load flow model. At last, taking the IEEE14 nodes system as an example, the wind farm is connected into this system, conducting reactive power optimization, and the results show that the QABC algorithm is better and has higher convergence precision, effectively avoiding the premature, compared with the traditional artificial bee colony algorithm(ABC).
Keywords:wind farm  probabilistic power flow  two point estimation method  multi-objective reactive power optimization  AHP  quantum artificial bee colony algorithm
