AB  - Integration of Distributed Generation (DG) generates problems for the protection 
      of Distribution Networks (DNs) in power systems. When DG is integrated into a 
      power distribution system (DS), the radial nature of the network is altered and 
      the power starts to flow in a reverse direction. In addition to the reverse flow 
      of power, the DG upsurges the fault current level and affects the existing time 
      intermission coordination of the protective overcurrent relay. This study 
      proposes a reverse power relay (RPR) and Fault Current Limiter (FCL) to mitigate 
      the fault current level and reverse power flow in a Distribution Network (DN) by 
      the use of DG. The FCL works only as a unidirectional fault current limiter 
      (UFCL) by restricting the flow of fault current that occurs in the main grid (MG) 
      of the DG. However, FCLs can protect the flow of fault currents from the MG by 
      affecting the operational flexibility and reliability of the DG. To overcome the 
      flow of fault current of the DG, this study proposes RPR to monitor the power 
      flow to the DG. Collectively the study focuses on the protection of radial DS by 
      using RPR and UFCL. The analysis and the modeling were conducted on the 15KV DN 
      of the radial feeder in Debre Markos DN. The 3Phi fault analysis (which is more 
      severe than others) was performed to validate the protection capability of the 
      mitigation techniques which were proposed in this study.
