Abstract

In a high proportion of renewable energy infiltration penetration, the power system presents low inertia damping characteristics. The traditional synchronous reference coordinate phase-locked loop （SRF-PLL） based on PI controller is more vulnerable to the fluctuation of new energy, resulting in poor phase-locked output results, which leads to a series of oscillation problems of grid-following converter. A phase-locked loop based on first-order linear ADRC （LADRC-PLL） is proposed. By comparing and analyzing the frequency domain characteristics of first-order LADRC-PLL and traditional phase-locked loop based on PI controller （PI-PLL）, the advantages of its disturbance rejection performance are explained. A simple parameter design method is proposed to simplify the parameter design of PLL. Under the same bandwidth scale comparison, it shows the limitations of the application of high-order LADRC in the phase-locked loop of grid connected converter. The simulation of PLL and the experimental results based on hybrid active neutral point clamped （HANPC） grid connected converter show that the proposed LADRC-PLL has more accurate phase locking results in disturbed environment, and is more suitable for new power systems with high proportion of renewable energy.
