Dynamic Load Flow Solution In Radial Distribution Network

This paper a ims at developing a new method of load f low involving dis tr ibuted generator for the improvement o f vo ltage prof i le . The involvement o f d istr ibuted gener a tor result s in improved vol tage regula t ion due to increase in the magni tude of the vo ltage. Whereas the load f lo w solutio n gives the so lut ion in lesser t ime due to lower i terat ion and thus lower computat ional t ime dur ing fault . The node a t which dis tr ibut ed generator i s connected is independent o f node and branch number. In the method proposed here, simple equations have been used to ca lculate the magnitude of the vol tage and in case o f high load condit ion; the vo ltage prof i le can eas i ly be improved by imp lement ing d is t r ibuted genera t ion connected wi th se l f conver t ing s tat ion arrangement. This method deals wi th the to ta l vol tage profi le to speci fied area o f load and involves nodes o f the the connected dis tr ibution substa t ion, la terals and sub laterals. Dur i ng faul ty condit ion, the dis t r ibuted generator co mpares the vol tage rat io (obta ined by dividing the vo ltage af ter the faul t wi th the vol tage jus t a fter the faul t) and compensated the vol tage di fference, as required, to maintain the sys tem heal thy.
