摘要
提出了一种配网故障指示器的优化配置方法,通过合理规划故障指示器的数量和位置,使得在保证供电可靠性的前提下最大的降低成本。综合考虑设备投资成本、运行维护费用以及停电损失等因素建立数学模型,并用细菌觅食算法进行求解。针对细菌觅食算法在解决离散域问题时存在的缺陷,通过定义进化域的方法确定细菌的前进方向,改进了其趋化算子,使得算法能很好的解决0~1规划问题,并通过设立电子公告板避免了迁徙算子有一定几率删除最优解的可能性。通过对IEEE 33系统进行仿真证明了该方案的有效性及科学性。
This paper proposes a method of the optimal configuration of fault indicator in distribution network,which is the maximum to reduce costs under the premise of ensuring the power supply reliability,through reasonable planning the number and installation location of fault indicator. With the consideration of equipment investment costs,operation maintenance costs and interruption costs,the mathematical model is solved by bacterial foraging algorithm（ BFA）. In view of the BFA existed in solving discrete domain,by defining the evolution domain to determine the direction of bacteria to promote chemotaxis solution,which can make it to solve 0 ~ 1 programming problem well,and through setting up electronic bulletin board to avoid the migration operator,we have a chance to remove the possibility of the optimal solution. Based on IEEE33 system simulation,the results prove the effectiveness and scientificity of the scheme.
