基于有功无功联合调整的动态潮流

提出了一种新型潮流算法,可同时考虑无功功率的区域平衡以及系统负荷变化所产生的净加速功率,并通过有功和无功的联合调整以获得更合理的潮流结果。计算过程取消了常规潮流算法定义的节点类型,使所有节点均参加有功和无功迭代,避免了人为确定节点类型对潮流分布的不良影响。最后通过IEEE30节点系统将所提算法与常规潮流算法、动态潮流算法进行了比较,结果表明所提算法能够改善系统的有功和无功功率分布。

A Dynamic Power Flow Algorithm with Joint Regulation of Active and Reactive Power

A new power flow algorithm, in which both area balance of reactive power and pure accelerating power caused by the variation of system load are simultaneously considered, is proposed and by means of joint regulation of active and reactive power a more reasonable power flow calculation result can be obtained. The bus types defined in conventional power flow algorithm are canceled, and all buses of the system participate in active and reactive power iterations, therefore the adverse impact of factitiously defined bus types on power flow distribution can be avoided. By means of IEEE 30-bus system, the proposed algorithm is compared with conventional power flow algorithm and dynamic power flow algorithm, and comparison results show that the proposed algorithm can improve the distribution of active and reactive power.
