【摘要】：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。
[Abstract]:In a system with multiple DFACTS devices, each controller is designed separately for different control functions, which makes each control function isolated or even contradictory. The coordination of the DFACTS controller is transformed into a multi-objective optimization problem. The single load infinite distribution system with static Var compensator (DSVC) and static synchronous compensator (DSTATCOM) in distribution network is taken as the research object. The parameters of the DFACTS controller are optimized by using the non-dominated sorting genetic algorithm (NSGA- 鈪，
