摘要
配电网运行状态复杂多变,正常运行的运维压力增加,需要分析处理的数据呈爆炸式增长,因此配电网对信息与计算资源的需求日益增长。为了提供有效精准的配电网故障定位服务,考虑配电网智能终端自身资源局限性,提出了一种分布式智能终端优化配置方法。基于图论表达配电网拓扑结构,以优化配电网片区内分布式智能终端综合计算负荷为目标,建立分布式智能终端优化配置模型,并提出基于拉格朗日乘数法的模型求解方法。以IEEE33节点配电系统为例,验证了分布式代理优化配置方法的正确性。
The operation state of distribution network is complex and changeable,the pressure of normal operation and maintenance is increasing,and the data needed to be analyzed and processed is growing explosively.The demand for information and computing resources of distribution network is growing day by day.In order to provide effective and accurate distribution network fault location service,considering the resource limitations of distribution network intelligent terminals,a distributed intelligent terminal optimization configuration method was proposed.Based on graph theory to express the topology of distribution network,the optimal configuration model of distributed intelligent terminals was established to optimize the comprehensive calculation load of distributed intelligent terminals in distribution network area,and a solution method based on Lagrange multiplier method was proposed.Taking IEEE33 bus distribution system as an example,the correctness of the method was verified.
