Self-Healing Method for Differential Protection in Intelligent Distribution Networks with DG Based on Multi-Agent Technology
Due to the variation of power flow direction with distributed generation in intelligent distribution networks containing DG,the self-healing effect of distribution network faults is difficult to guarantee.Therefore,a multi-Agent based self-healing method for differential protection in intelligent distribution networks with DG is proposed.By constructing a multi-Agent based MAS architecture and applying it to differential protection and self-healing control in intelligent distribution networks with DG,differential protection is completed in the data processing layer of the MAS architecture,and fault self-healing is achieved in the coordinated control layer of the MAS architecture.The results show that this design method can not only restore the power in the fault area of the distribution network,but also achieve ideal results in terms of operation frequency,line loss,and power factor.
