Simulation and Analysis of Dynamic Characteristics for Power System with Large-scale Wind Power

Abstract

It is important significance to study the dynamic characteristics of power system with large-scale wind power, because large-scale wind power access to power system has a great influence on the stable operation of the power system. In this paper, the operation principles of wind turbines, hydropower units and thermal power units are analyzed respectively and the corresponding mathematical model are established. Based on these mathematical models, the multi-source hybrid electric power system model containing wind turbines, hydropower units and thermal power units is built up. The multi-source hybrid electric power system model is simulated and analyzed in the condition of wind speed fluctuation. Simulation results show that when the power output of wind turbines changes, the multi-source hybrid power system model can accurately describe the dynamic characteristics of power system.
