Modern renewable energy systems (RES) require fault ride through (FRT) operation in order to provide voltage and frequency support to the power grid when faults occur. The grid synchronization of a RES could be ensured by the appropriate operation of a phase-locked loop (PLL). A new hybrid PLL (d α β PLL) has recently been suggested by the authors and could operate accurately and faster than the other existing PLLs. The d α β PLL could be a very useful tool in the FRT operation of a RES, since the faster performance of the new PLL could boost the time performance of the FRT algorithm when a disturbance occurs. This paper investigates the performance of the flexible positive and negative sequence control (FPNSC) when the new d α β PLL is used. The paper also deals with the improvement on the FRT operation of the RES that could be obtained from the outstanding performance of the d α β PLL.
