Abstract

To address the issue of adjacent-line inverter-interfaced distributed generation（IIDG） disconnection caused by secondary voltage dips at the point of common coupling（PCC） after front-accelerated auto-reclosing operates on a permanent fault, an improved low-voltage ride-through（LVRT） strategy applicable to the distribution network with reclosers is proposed. Based on the LVRT specifications of IIDG, the impact of auto-reclosing on LVRT is analyzed, and the successful LVRT process is divided into three stages （voltage dip, voltage recovery, and power restoration）. Prior to auto-reclosing actuation, the adjacent-line IIDGs terminate the ongoing LVRT process in advance by identifying these stages. When secondary voltage dips occur due to front-accelerated auto-reclosing on a permanent fault, the adjacent line IIDGs can initiate a new LVRT cycle to prevent grid disconnection. Simulation results verify that the proposed strategy avoids IIDG disconnection during secondary voltage dips without altering the original fault recovery scheme, exhibiting high practical value.
