چکیده مقاله:
The paper provides a new index in order to determine optimal size andlocation of DG units, minimize system power loses and DG cost, optimizevoltage profile and increase voltage stability margin. A multi- objectiveoptimization method is used in order to size and allocate DG units; OptimizedPartical Sowrm Optimisation Algorithm (PSO) is used for this aim. The loadvariations effects on optimal DG capacity are studied in this paper. The loadvariations effects on voltage profile, voltage stability and loses are determinedafter bus and capacity identification. Linear load variations are consideredfrom 50 to 150% of base load (with 10% steps). Present constraints are systemvoltage, feeders flow and DG capacity limitations. Offered method is used for34 bus experimental system. All experiments are simulated in MATLABsoftware. The simulation results show considerable effects of system loses,voltage profile improvement and increased voltage stable margin throughexpending the least cost.
