Robust Multistage Distribution Network ExpansionPlanning Considering RES Using Taguchi'sOrthogonal Array Testing

Distribution network expansion planning is one ofthe most important challenges of distribution companies.Nowadays due to increasing the penetration level of renewableenergy resources (RESs) including wind turbines, solar panelsand electric vehicles, the uncertainties of power system isdrastically increased. Thus it is necessary to develop novelmethods to cope with these uncertainties. Several methods havebeen developed to tackle with uncertainties that can becategorized in three large classes: probability distributionfunctions, stochastic methods and robust optimization. In thispaper, a new method based on the robust optimization usingTaguchi’s orthogonal array test is utilized to take into accountthe uncertainties of loads and wind turbines. The simulationsare carried out on an illustrative distribution system. The resultsof simulation show the accuracy and efficiency of the proposedmethod.
