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.
