Abstract :
In this paper, a networked control strategy of current-sharing for inverter parallel operation is proposed, which takes instantaneous power as transmission data to equalize the output power among inverters. The mathematical model for networked control system with time-delay and data dropouts is built. To describe the influence of data transmission for networked control system, allowable time-delay for adjacent transmission data is quantified and the stability analysis method for the event-driven system is presented. The experimental results demonstrate the validity of the current-sharing strategy and the mathematical analysis.
