PSO-dynamic modification algorithm based static load models identification

The Particle Swarm Optimization(PSO) algorithm with global optimization ability is applied for load model parameters identification in this paper.The parameters are real-time corrected by the dynamic modification method with the load voltage change considering.Simulation analysis results verify the validity and feasibility of PSO-dynamic algorithm.Comparing with the linear regression analysis based dynamic modification method,the algorithm can enhance the identification accuracy of load model,and the established model is suitable for the description of load static characteristics in large range voltage.
