MODELLING AND SIMULATION OF THE IMPACT OF POWER GENERATION ON THE DISTRIBUTION SYSTEM
Abstract
Withtheeverincreasingdemandofelectricityconsumptionandtheincreasinginopenaccessparticularlyinrestructured(deregulated)environment,transmissionlinecongestionisquitefrequent.Formaximummitigationandbenefitofthiscongestion,propersizingandallocationofdistributedgenerators(DG)areardentlynecessary.Asimplemethodispresentedinthispaperfortheoptimalplacementandsizing of this type of generators in distribution electricpower networks. A conventional iterative simple searchtechnique combined with Newton Raphson (N-R) methodof load flow study is applied on a real 15-bus distributionfeeder model and on the standard IEEE14-bussystem.ThePowerworldSimulator©v.15commercial software have been used for the modeling,visualization,simulationandanalysisofthepowersystemsunderstudy. Theobjectiveoftheformulationpresented here is to lowerdown effectively both energycostandpowerlosses.Thepaperalsoemploysanappropriate weighting factor in order to balance the costand loss quantities, and at the same time to formulate theoverallobjectivesleadingtohighpotentialbenefit.
