Integration of Distributed Generations (DGs) to power system offers several advantages such as reduced transmission and distribution system resources, increased reliability, stability, better power quality. . And these depend on the system configuration, type and capacity of DG, location of integration and management of DG, The optimal allocation of DG is needed for increasing the benefits in power system. Power quality is a major issue to be considered for the analysis in power system when distributed generators are integrated. Operation of Renewable distributed generators (RDG) will increases the rate of power quality issues, hence extra care has to be considered when RGD ‘s are integrated. Here analysis is carried out on variation of voltage profiles, varying load, stochastic wind power and power losses. The analysis is carried out to compare the results before and after optimal integration of DGs. Optimal integration is done based on the weighted sum of multi objective function based on Voltage Deviation, power losses and . This paper presents the results of simulations for standard Ieee33 bus Distribution systems.
