在含有多个DFACTS装置的系统中,各控制器是针对不同的控制功能单独设计的,这使得各个控制作用相互孤立甚至是矛盾的。针对单独设计的DFACTS控制器间存在交互影响的问题,将DFACTS控制器的协调转化为多目标优化问题,以含配电网静止无功补偿器( DSVC)和配电网静止同步补偿器( DSTATCOM)的单负荷无穷大配电系统为研究对象,运用带精英策略的非支配排序遗传算法( NSGA-II)对DFACTS控制器的各参数进行优化。时域仿真结果表明,优化后的控制器间的交互影响得到了较好的抑制,系统的动态特性得到了较大提高,验证了NSGA-II算法的有效性。
在含有多箇DFACTS裝置的繫統中,各控製器是針對不同的控製功能單獨設計的,這使得各箇控製作用相互孤立甚至是矛盾的。針對單獨設計的DFACTS控製器間存在交互影響的問題,將DFACTS控製器的協調轉化為多目標優化問題,以含配電網靜止無功補償器( DSVC)和配電網靜止同步補償器( DSTATCOM)的單負荷無窮大配電繫統為研究對象,運用帶精英策略的非支配排序遺傳算法( NSGA-II)對DFACTS控製器的各參數進行優化。時域倣真結果錶明,優化後的控製器間的交互影響得到瞭較好的抑製,繫統的動態特性得到瞭較大提高,驗證瞭NSGA-II算法的有效性。

In the power distribution system with multi DFACTS devices,controllers are separately designed aiming at different functions,which makes the controllers be isolated or even contradictory. Aiming at the problem of reciprocal influence between separately designed DFACTS controllers,the coordination of the DFACTS controllers has been turned into multiple target optimization problems,so the single-load infinite-bus distribution system with DSVC and DSTATCOM will be regarded as the research object. The NSGA-II( Non-Dominated Sorting Genetic Algorithm-II)is adopted to optimize the DFACTS controller parameters. Time-domain simulation results show that the recipro-cal influence has been greatly alleviated and the dynamic performance has been improved,which verify the effective-ness of the algorithm.
