A Method Of Reactive Power Compensation Dispatch Based On Matrix Superposition Theorem

With the development of the power grid,the structure of grid had become more complex.The coupled relationships of the reactive compensation in nodes can not be ignored.It is important to detect the connections of the nodes among power grid in order to server the voltage and reactive power control.This paper proposes a supplementary method to gain the coupled relationships which are represented by parameters of grid quantitativly in distribution grid using matrix superposition principle.The test vertificates that the method can provide the coordinated dispatch in a region.The distribution tables gained from the method give a clear profile.The method can avoid overcompensation or lack compensation and offer a good arrangement of reactive power resource.
