Abstract

This paper proposes a constant voltage and frequency （VF） control strategy for the photovoltaic-storage-charging islanded microgrid under communication network. This strategy is a master-slave control structure,the master controller adopts super twisting sliding mode control （STSMC） to maintain voltage stability. The slave controller adopts sliding mode control （SMC） to transmit and share current data using CAN and ZigBee networks for power distribution. The maximum allowable delay bound （MADB） is calculated using a bisection iterative algorithm, and the effect of time delay greater than MADB on the system is analyzed. The simulation results show that STSMC has smaller control error, shorter response time and stronger anti-delay ability than PI and SMC.

Key words
