摘　　要：风储联合发电系统能够有效解决风电大规模并网过程中存在的"并网难"和"弃风"等问题,如何建立风电机组和储能单元之间的协调控制策略是实现风储联合发电系统稳定运行的关键。为研究风储联合发电系统的运行特性,首先建立直驱永磁风力发电机组、储能单元的数学模型;其次,根据建立的各模块数学模型,提出直驱永磁同步风电机组机侧整流器采用转速外环和电流内环、网侧逆变器采用电压外环和电流内环以及储能单元逆变器采用间接功率控制的控制策略,并在各模块控制策略的基础上建立风电机组与储能单元之间的有功协调控制;最后,基于MATLAB/Simulink仿真结果表明,所建立的模型以及协调控制策略的正确性和有效性,为风储联合运行系统的进一步研究提供参考。In order to study the operation characteristics of wind and energy storage combined generation system, firstly, a mathematical model of direct drive permanent magnet wind turbine and energy storage unit is established. Secondly, an effective control strategy is proposed, which uses speed outer loop and current inner loop for the rectifier in direct drive permanent magnet synchronous wind turbine generator side, uses voltage outer loop and current inner loop for grid side inverter, and uses indirect power control for energy storage unit inverter. And on the basis of the control strategy of each module, the active power coordination control between the wind turbine generator and the en- ergy storage unit is established. Finally, simulation results based on MATLAB/Simulink show that the proposed mod- el is eorreet and effective, which provides a reference for the further research of wind and energy storage combined generation system.
