Optimal algorithm is an important factor for identifying the dynamic load model parameters accurately which with the nonlinear characteristic. The paper adopts the improved genetic algorithm with optimal reservation strategy (OGA) at the beginning and finds that the problem of convergent to local optimal solution is still exist. Considering the Simulated Annealing algorithm (SA) has good performance in respect of local searching characteristic which can prevent convergence from local optimal, so the hybrid algorithm combined with SA algorithm and GA algorithm (GASA) is proposed in this paper. Case studies showed it can improve the accuracy of parameter identification and reduce the P Q fitting errors .The efficiencies of identifying substation load model based on the PMU measure data is proved as well.

In the paper the models of dynamic forces generated by people running referred to two running techniques i.e. forefoot strike running and heel strike (rearfoot strike) running are presented. The model of forces generated during forefoot strike running was refined taking into account proposals of various authors and the results of author’s own laboratory tests of running people. The model of the forces generated during heel strike running is a new author’s proposal elaborated on the basis of the results of laboratory tests. Presented results of analyses and the proposal of a new dynamic load model correct and complement the shortcomings of the existing models and complement the shortage of recommendations in the area of dynamic forces generated during heel strike running technique.
