The high penetration of distributed photovoltaic (PV) can bring about huge economic and environmental benefits in the distribution network. While at the same time, it can result in the voltage violation in power system. Due to the two‐quadrant power output characteristics of PV inverter, it is possible to regulate voltage violation via utilising the reactive power output of PV inverter instead of traditional reactive power compensation devices. In this study, a global voltage regulation strategy has been addressed by taking the indices of voltage violation regulation and active power loss of distribution network into consideration, and voltage limit violation is processed based on the concept of hard and soft voltage boundary constraints. Differential evolution algorithm is introduced to solve the optimisation model. Finally, it was simulated in IEEE‐33 node distribution system, results of example analysis confirm that the proposed strategy can optimise the reactive and active power of PV, which can not only regulate the voltage violation but also realise the economic operation of the distribution system.
