基于PMU的配电网状态估计

State estimation of distribution network

配电网状态估计在了解配电网运行情况时起到至关重要的作用,向量测量单元(PMU)能为状态估计提供实时的同步数据。提出以支路电流为状态量,以PMU采集的数据为量测量对配电网进行状态估计,并用IEEE33节点证明所提算法的有效性和可行性。

Distribution network state estimation played an important role in understanding the operation of distribution network, the phase measurement unit （PMU） could provide real-time synchronization data for state estimation. This paper proposed the method to take the branch current as the state variables, and the data collected by the PMU was used to estimate the state of the distribution network. Lastly, the effectiveness and feasibility of the algorithm were proved in IEEE33 nodes.
