【摘要】：针对区域无功需满足多负荷水平下的平衡要求,以及二级电压控制以主导节点为控制中心的特点,提出了考虑区域无功平衡的主导节点选择和无功分区的优化方法。该优化方法以电源对主导节点的可控性最强,主导节点对本区域负荷节点的可控性最强以及主导节点对其他区域负荷节点的影响最小为目标,以多负荷水平下区域静态无功平衡为约束,采用基于目标相对占优的遗传算法进行求解。其中,为表征主导节点对负荷节点的可控性,提出了主导节点的控制空间。该控制空间以主导节点对负荷节点的电压控制灵敏度为基础,通过逐次递归的方法进行构造。IEEE 39和IEEE 118节点系统的仿真结果论证了该方法的有效性。
[Abstract]:In view of the requirement of regional reactive power balance at multi-load level and the characteristic that the dominant node is the control center of two-stage voltage control, a method for selecting dominant nodes and optimizing reactive power zoning considering regional reactive power balance is proposed. This optimization method aims at the most controllable power supply to the leading node, the strongest controllability of the leading node to the local load node, and the least influence of the leading node on the other regional load nodes. With the constraint of regional static reactive power balance at multi-load level, a genetic algorithm based on objective relative dominance is used to solve the problem. In order to characterize the controllability of the dominant node to the load node, the control space of the leading node is proposed. The control space is based on the sensitivity of the dominant node to the voltage control of the load node. The simulation results of constructing the .IEEE39 and IEEE 118-bus systems by successive recursive method demonstrate the effectiveness of the method.
