Abstract

Three-phase unbalance control strategy is used to improve the system performance when three-phase unbalance load or fault happens. However, when the distributed generation selected as the master in the microgrid stop working, due to the loss of system voltage direction, the traditional control strategy is no longer applicable. In order to maintain the stable operation of the SST (Solid State Transformer) under passive microgrid model when three-phase unbalances occur in the microgrid, the paper came up a novel balance control strategy under passive microgrid model. The control strategy is based on the voltage and current double-loop control strategy, and uses a negative sequence current module to calculation the negative sequence reference current, prevent three-phase unbalance from entering into distribution grid side and improve the control performance of the SST. The simulation results have proved the validity and efficiency of the three-phase unbalance control strategy.
