Abstract: This paper presents a methodology for sustainable operation of the distribution network with optimal placement and sizing of dispatchable DGs and shunt capacitors. The objective of this work is aimed at reducing the feeder current drawn from the grid and minimizing the annual energy losses along with real power loss reduction and improvement of voltage profile. An average hourly variation of load demand profile is considered. Sensitivity analysis based on voltage stability index is used to obtain the location of dispatchable DGs and shunt capacitors. The size of the dispatchable DGs is optimized using GA optimization tool. Annual cost savings is computed to show the economic benefits of the operation. Effectiveness of the proposed methodology is demonstrated on a 33 node distribution network. The results demonstrate the effectiveness of the proposed methodology over other existing methods available in the literature.
