Stability Characteristics Research and Operation Strategy Optimization of Wind-Thermal Bundled System
In order to solve the synchronous stability problem of bundled transmission of offshore wind power cluster and thermal power in western Guangdong,firstly the synchronous stabilization characteristics and influencing factors of the wind-thermal bundled system are studied in this paper,and then the optimization strategies of operation modes for improving wind power penetration rate of wind-thermal bundled system and giving priority to wind turbines with good synchronous stability characteristics are proposed.Finally,a real-time simulation system of wind farm cluster hard-ware-in-the-loop access is constructed for simulation verification,and the simulation results show that the proposed synchronous stability enhancement strategy can improve the stability limit of the wind-thermal bundled system,which strongly improves the rate of wind power on-grid consumption and the level of grid security and stability.
