Impact of Distributed Generation on Voltage Profile in Distribution Systems: A Current Mismatch based Load Flow Analysis Approach

Conventional load flow methods modifications are necessary when taking into account the integration of distributed generations (DG) in electric distribution systems. In the present work, the impact of the DG's operating modes (PQ-PV) on the voltage profile when considering changes in their sizes and locations is studied. The load flow based current injection mismatches is proposed. The ten-bus test distribution system is used for validation purposes. Different scenarios are considered and some corresponding results are discussed.
