基于01整数规划的多目标最优PMU配置算法

针对目前缺乏多目标PMU配置方法,提出了一种基于线性01规划的多目标优化配置算法。并在此基础上导出了三种特殊模型,分别处理系统在正常运行方式下完全可观测的PMU布点问题,在线路N-1故障时系统仍可观测的PMU布点问题及在PMU N-1故障时系统仍可观测的PMU布点问题。该方法的突出特点在于能够同时将以上三种布点需求使用统一的形式同时处理,并且最终的布点方案在保证PMU数目最少或保证配置PMU所需费用最少的基础上获得了最高的测量冗余度。通过IEEE30、IEEE 57、IEEE118节点系统布点验证了该方法的有效性和灵活性。

Multi-object PMU optimization placement algorithm based on 01 integer program

Considering the need of multi-object PMU placement,this paper proposes a new multi-object PMU placement optimization algorithm based on 01 integer program.Also three special models are derived to achieve the full observability of power grid when under normal condition,any line tripped or any PMU malfunctioned.The advantage of this new algorithm is that it can handle all the tree objects at the same time and also achieve high measurement redundancy with minimal PMUs or minimal costs.The numerical simulation on IEEE 30-bus system,IEEE 57-bus system,IEEE 57-bus system and the effectiveness and flexibility of the proposed algorithms are verified.
