Voltage stability is critical in the power distribution network. This paper aims to study the dynamic voltage stability problem. When wind generators reach maximum reactive power output, the bus voltage will operate near its steady-state stability limit. In order to avoid voltage instability, a dynamic L-index minimization approach is proposed by incorporating both wind generators and other reactive power resources. It then verifies the proposed voltage stability enhancement method using real load and wind generation data in the IEEE 14 bus system. The simulation results show the benefits of proposed methodology in solving dynamic-state voltage stability enhancement problem.
