PMU布点问题需要在满足一定约束的条件下同时优化2个相互冲突的指标:配置PMU的数目(或费用)最少和测量冗余度最高。文章提出基于线性0-1整数规划的模型并用来求解系统正常运行方式下完全可观测的PMU配置方案,还分别给出了线路N-1故障时以及PMU N-1故障时系统仍可观测的PMU配置模型,该模型不仅考虑了PMU实测数据,还计及了可用的潮流数据和零注入节点。文章通过将零注入节点转化为潮流已知线路巧妙地回避了模型的非线性问题。通过对IEEE测试系统和浙江电网进行仿真,验证了所提方法的有效性和灵活性。
PMU deployment issues need to be optimized at the same time to meet the constraints of two conflicting indicators: the number of PMU configuration (or cost) and the highest measurement redundancy. In this paper, a model based on linear 0-1 integer programming is proposed and used to solve the completely observable PMU configuration scheme in normal operation mode. The system is still observable at the time of line N-1 fault and PMU N-1 fault respectively PMU configuration model that takes into account not only PMU measured data but also available power flow data and zero injection nodes. The article cleverly avoids the nonlinear problem of the model by converting the zero-injected node into a tidal current. Through the simulation of IEEE test system and Zhejiang Power Grid, the effectiveness and flexibility of the proposed method are verified.
