In order to improve the load capacity of it, a voltage sensitivity matrix based distribution network voltage control method is proposed. Firstly, by analyzing the influence of node injection power variation on node voltage, the voltage sensitivity matrix associated with active power and reactive power of each master node is constructed. Then, according to the voltage sensitivity matrix, the reactive power adjustment capability of the distributed photovoltaic inverter is fully utilized, and the node voltage of the distribution network is quickly controlled within the working range. The simulation results show that the method can effectively reduce the voltage deviation of distributed distribution network under various working scenarios and improve the voltage quality.
