Impact evaluation of wind power integration on power system using optimal power flow tool

摘要

With wind power integrated into a grid, the impact of wind power on a power system becomes a major concern. This paper mainly investigates the impact of wind power integration considering three issues - wind speed, number of wind turbines or wind power penetration (WPP) level. The impact of wind power is analysed by the optimal power flow (OPF) tool. First, the OPF model with WPP is constructed. The Levenberg-Marquardt method was then employed to solve the OPF problem. Finally, numerical simulations for the modified IEEE-30 node system with WPP are carried out. According to the simulation results, the impacts of wind speed, wind turbine number and WPP level on the static performance of the power system are systematically analysed.
