Summary:With the large-scale development of distributed PV in our country, the control of voltage in distribution network is becoming more important. In order to improve the hosting capacity for distributed PV generation in distribution network, a voltage control method of distribution network based on voltage sensitivity matrix is proposed in this paper. By analyzing the influence of variation of node injection power on node voltage, the sensitivity matrix of active and reactive power for each main node voltage is established. Then make full use of reactive power regulation capability of distributed PV inverters which are chosen according to the value of sensitivity factor, and the fast control of voltage will control the voltage to the operating range. Finally, the simulation results show that the proposed method can improve the voltage level of distribution network.
