【摘要】 提出一种基于禁忌算法的多目标无功优化方法。在多目标优化中,包括了距离裕度和网损两项性能指标。首先在给定负荷增长方式的前提下,利用改进连续潮流法快速地找到电压崩溃点,进而求得当前运行点离崩溃点间的距离,并以此距离作为裕度指标,然后采用模糊集理论将裕度指标和网损指标两个目标优化问题转化为单目标优化问题,最后利用改进的禁忌算法对该单目标进行优化,使系统在满足约束的情形下既经济又安全地运行。文章在IEEE14节点系统上验证了该算法的优越性。更多还原

【Abstract】 This paper proposes a method for multi-objected reactive optimization taking voltage stability into account based on tabu algorithm.At first,voltage collapse point is traced by improved continuation power-flow method under the premise that load increasing pattern is given,the distance away from collapse point which can be regarded as margin index can be got at the same time.Then the two objectives including margin index and transmission loss are converted into single objective by adopting fuzzy set theory,improved tabu algorithm is used for optimizing this single objective,at last,in order to make system operate in security and economy under conditions.The advantage of this method is validated on IEEE14 bus system.更多还原
