Abstract: Currently, distributed photovoltaic (DPV) presents a large-scale grid-connected trend, and the volatility of PV output causes the load flow of high PV penetration distribution network to appear anti-transmission, triggering frequent distribution network voltage overruns, bringing challenges to the safe and reliable operation of the power network. In view of this, this paper analyses the distribution network voltage influence law and control principle under different PV penetration conditions. On this basis, the current voltage control schemes for high PV penetration distribution networks are reviewed, and the adaptation scenarios and advantages and disadvantages of different control schemes are commented. At the same time, key technologies such as distributed generation cluster division methods, cluster optimal control, distributed control algorithms and other key technologies are highlighted and described. Finally, the future development direction of active distribution network voltage control technology is outlooked.
