Parameter Identification of HVDC Transmission System Model Based on Intelligent Optimization Algorithm

With the construction of cross-regional HVDC transmission system and a large number of new energy power generations connected to the power grid, the modern power system has put forward higher requirements for the accuracy of simulation analysis model. Unsuitable model and model parameters are the key causes of power system simulation error. In this paper, based on the power system simulation analysis software PSASP, combined with a variety of intelligent optimization algorithms, the identification method of model parameters of the HVDC transmission system is proposed. At the same time, its effectiveness is verified by a simulation example, and the accuracy of the relevant algorithms is analyzed and compared.
