The growing rate of energy consumption is a reason for establishment of new power plants which leads to increment in fault current level. One of the solutions to overcome this problem is utilization of fault current limiters (FCLs). Another concerning issue in energy generation is the satisfactory voltage quality in grid and to deal with it, a power electronic based device, known as dynamics voltage restorer (DVR), is introduced. However, in power grids FCL and DVR are independent devices. In this paper, a novel topology is proposed which linking DVR and FCL, provides substantial benefits. According to grid state, the DVR-FCL has four operating modes. Moreover, for appropriate operation of the presented topology, a suitable control method is proposed. The DVR-FCL and the control method are verified considering the simulation results.
