Loads in the power systems are one of the most important parts in the network studies which have been less focused because of shortages and lack of sufficient data. In this paper, an adaptive load modeling method for large scale power systems is proposed which is not only useful to stability and protection analysis, but also is suitable for long time dynamic simulations. So, direct measurement method and dynamic simulation of reactive power resources has been considered in this method. Least square method and Taboo search algorithm have been used to form the objective function of modeling problem and solve it respectively. comparison between simulation results and real data convincingly approves the accuracy of the mentioned method
