摘要
本文根据电力系统自身的特点,针对经济调度中的无功优化潮流问题,提出分层控制及计算的数学模型。应用大系统分解协调理论,采用按地区分块的空间分块法,将大系统的无功优化潮流问题分解为各子系统单独优化及主系统协调的问题。各子系统之间的联系采用互联节点。使用计算机网络进行分层计算,节省了计算机内存,提高了整体的运算速度。
The article presents a mathematical model of the hierarchical calculation for the problem of the optimal reactive power flow. The whole system can be divided into several dependent subsystems which are connected with each other by interconnectting nodes. Large scale system decomposition and coordination theory are employed in the method. This is a practical method to take computational requirements and transmitted information into consideration. Numerical results show that the execution time and memory requirments are reduced, and convergency property of the calculation is satisfactory.
