| Abstract: | PV curve influenced by load characteristics is analyzed in this paper.It is found that the load characteristics and the increase orderliness of power source output have great influence on the PV curve.A direct iteration algorithm for generalized power flow taking account of load characteristics is also investigated.Simulation results show that the algorithm doesn't need additional equation,is convenience to analyze the load characteristics influence to voltage stability,and is with high efficiency. |
