With the gradual increase of distributed photovoltaic（PVs）permeability rate in distribution networks

the problem of voltage overload due to the imbalance between power generation and load demand has become increasingly prominent. To make full use of the controllable resources for voltage regulation and

at the same time

reduce the amount of communication and calculation of the system

a kind of voltage control strategy of distribution network containing high permeability PVs is proposed on the basis of the approximate voltage sensitivity of the distribution network nodes and in combination with the characteristics of local control and distributed control. The strategy uses the local measurement data and distributed communication information and achieves economic and fast control of system voltage through the reactive coordination control and active optimization of the key nodes. The simulation results show that the proposed strategy has good voltage control effect and economy and can be able to reduce operation cost of system.
