Description:   New Method of Voltage Control Considering Distribution Network Containing Distributed Generation. Considering out of limit voltage in distribution network containing distributed generation(DG),a new method of voltage control is proposed,which is based on sensitivity analysis and consists of comprehensive regulations of outputs of DGs and switching capacitor groups.When out of limit voltage appears,the sensitivity of voltages in each node caused by input reactive power is worked out,with minimum shifts of nodes in system selected to be an objective function and harmony search algorithm adopted as calculating method,then the magnitude of outputs of sources and switching groups is determined comprehensively.Also the performances of voltage control with and without DGs and regulations by voltage sensitivity are compared.This paper deduced sensitivity matrix in cartesian coordinates,and employed IEEE-33 bus system to verify the control strategy,and verified its correctness and effectiveness
