The increasing usage of renewable sources into the existing conventional grids demands suitable control techniques to maintain the stability. Moreover, power quality, synchronization issues, and loss of generation must be avoided. This paper discusses a hybrid AC/DC network encompassing an interlinking voltage source converter coupling the hybrid networks and other renewables. The system aims at (i) load compensation at source end, (ii) reduction of total harmonic distortion (THD), (iii) reduction of oscillations in the power, and (iv) bidirectional power transfer between the AC and DC networks thereby meeting the abovementioned setbacks. To exert the objectives, the control scheme employs phase-locked loop (PLL) synchronization techniques aiming at fast and accurate detection of grid parameters. This paper presents an interesting comparison of different PLLs, such as SRF-PLL (synchronous reference frame-PLL), MAF-PLL (moving average filter-PLL), SOGI-PLL (second-order generalized integrator-PLL), ROGI-PLL (reduced-order generalized integrator-PLL), and CDSC-PLL (cascaded delay signal cancellation-PLL) in the control strategy of interlinking VSC. The system is validated for dynamic change in load, and the extensive results for both rectification and inversion operations of the system are obtained on a Software-in-the-Loop (SiL) platform using real-time digital simulator (RTDS, Opal OP4510).
