Optimal siting and sizing of multiple type DGs for the performance enhancement of Distribution System using Differential Evolution Algorithm

The necessity of Distributed Generation (DG) in the modern power system has increased greatly. Optimal placement and sizing DGs have a significant impact on objectives voltage stability enhancement, real reactive loss minimization security reliability. Different types such as Type I, II, III IVare placed. optimal these is found using Voltage Stability Index (VSI). done Differential Evolution (DE) algorithm. MATLAB simulation carried out standard IEEE 33-bus test system. performed for various combinations different DG. results show that index along with algorithm provides better profile compared to without
