Load Flow Analysis on Distribution Network Integrating Micro sources

Electricity distribution is the eventual stage in the delivery of electricity to the end consumers. A distribution system's network which carries electricity from the transmission system and delivers it to consumers. There are two types os distribution network , radial or interconnected. An interconnected network is generally found in more down town areas and will have numerous connections to other points of supply. These points of contact are normally open but allow various composition by the operating utility by closing and opening of switches. In distribution systems, the voltages at buses reduces when carried away from the substation, also the losing is high. The logic for decrease in voltage and high losses is the deficient amount of reactive power, which can be furnished by the shunt capacitors. The work proclaimed in this thesis is carried out with the objective of identifying the flawless locations and sizes of shunt capacitors and DGs to be placed in radial distribution system to have overall economy considering the saving due to energy loss cut down .The load flow of pre compensated distribution system is carried out at first stage. On the basis of load flow solutions, loss sensitivity factors (LSF) indicating the likely locations for compensation are computed. From LSF, the candidate number of buses is spotted. To diagnose the sizes of the capacitor for curtailing the energy losses. The contrasting method is tested for distribution systems at 11 KV voltage distribution system while taking the different sizes for capacitors and DGs
