چکیده مقاله:

The paper provides a new index in order to determine optimal size and location of DGunits, minimize system power loses and DG cost, optimize voltage profile and increasevoltage stability margin. A multi- objective optimization method is used in order to sizeand allocate DG units; Optimized Improve Partical Sowrm Optimisation Algorithm(IPSO) is used for this aim. The load variations effects on optimal DG capacity are studiedin this paper. The load variations effects on voltage profile, voltage stability and loses aredetermined after bus and capacity identification. Linear load variations are consideredfrom 50 to 150% of base load (with 10% steps). Present constraints are system voltage,feeders flow and DG capacity limitations. Offered method is used for 34 bus experimentalsystem. All experiments are simulated in MATLAB software. The simulation resultsshow considerable effects of system loses, voltage profile improvement and increasedvoltage stable margin through expending the least cost.
