平衡辐射状配电网状态估计的实用方案

A Practical Proposal for State Estimation at Balanced, Radial Distribution Systems

Panayiotis Moutis, Omid Alizadeh-Mousavi

摘要:

分布式资源的不断增加的部署和为负载提供的更多主动角色的机会已经改变了配电系统(DS)的先前单向和相对直接的操作简档。将需要密切监测DS的稳健性和足够的电力质量。输电系统的状态估计一直作为一种监测工具,它驱动系统范围的控制动作,从而确保电网的运行完整性。在这项工作中提供的DS的情况下,经典的状态估计的更新,不需要测量或估计的电压角的径向网络的功率流配方的基础上。

英文摘要:

The ever-increasing deployment of distributed resources and the opportunities offered to loads for more active roles has changed the previously unidirectional and relatively straight-forward operating profile of distribution systems (DS). DS will be required to be monitored closely for robustness and sufficient power quality. State estimation of transmission systems has consistently served as a monitoring tool, which drives system-wide control actions and, thus, ensures the operational integrity of the electric grid. An update to the classic state estimation for the case of DS is offered in this work, based on a power flow formulation for radial networks that does not require measurements or estimate of the voltage angles.
