【摘要】 本文提出一种新的用大系统分解——协调理论进行电力系统经济调度的算法。该算法按区域将一个大的电力系统分成几个子系统，各子系统之间通过边界点耦合，将边界点的电压及区域间交换功率作为协调变量。各子系统在给定的协调变量下求解，由协调级根据各子系统优化结果对协调变量进行修正，再进行新的一轮选代。本算法解决了由于各子系统设置虚拟平衡点而给协调带来的困难，并且由于选择电网运行数据作为协调变量，有利于初值选择和在选代中修正，改善了收敛性。更多还原

【Abstract】 This peper presents a new algorithm for power systems economic dispatching. The large scale power system is divided into some subsystems,and these subsystems are interconnected through boundary nodes. The exchanging power passing through boundary nodes and the voltage on boundary nodes are selected as coordinatinn varisbles. Each subsystem is solved under given values of coordination variables, and coordination varisbles are corrected by the coordination layer. Then, a new iteration is going on. In this algorithm, the trouble on coordination due to setting a imaginary slack bus for each subsystem is overcomed. The convergence is also improved.更多还原
