Limited by the singularity of the control objective and the control means

traditional LVRT strategies used for asymmetric faults in multi-PV power systems may suffer from voltage and current violation

frequency stability issues

and the lack of coordination. To address these issues

a fault ride-through coordination strategy for multiple PV sources based on the consensus algorithm is proposed. First

during the initial stage

the idle capacity of the photovoltaic inverter is given priority for reactive power support to maintain the active power output capacity of the photovoltaic power supply. Simultaneously

consistent iteration is initiated to update the reference values for positive-sequence active and reactive currents. In the second stage

to fully utilize the capacity of the photovoltaic inverter and keep the maximum phase voltage within the safe operation range

a calculation formula for positive and negative sequence reactive currents is derived by integrating consensus algorithms. Subsequently

updates and coordination of positive and negative sequence reactive currents from the photovoltaic output are carried out provided that positive sequence active current remains unchanged. Finally

simulation results in MATLAB show that the proposed method can realize the coordinated control of fault ride-through of multiple PV sources.
