摘要：Sustained power frequency overvoltage control strategy is an important part of power system restoration plan. The existing sustained over voltage control methods are based on static network, ignoring the dynamic restoration process. By choosing restoration targets as milestones, the dynamic process can be divided into several restoration sequences, each sequence consists of several restoration operations. In this paper, a dynamic multi-objective sustained overvoltage control model based on the restoration sequence is proposed, which takes the coupling of voltage control schemes at different stages into consideration. The objective functions adapted to the characteristics of restoration process are defined, including the operation risk of restoration sequence, adjusting time of voltage control scheme and voltage deviation of energized buses. The effectiveness of proposed model is verified by the simulation results of dynamic and static optimization under different restoration scenarios in Shandong power grid.
