摘　　要：随着全球风力发电场的电力产量大幅增加,需要能量存储系统来动态补偿风能的间歇性并提高电力系统的稳定性。为满足上述需求,首先以两级静态同步变流器(SSC)集成到高压直流输电系统为主线思路,开展了双馈电机飞轮储能系统(FESS)的研究。其次,针对电力系统电压波动、负载变化及风力资源不确定性,提出了虚拟阻抗电压电流双闭环控制策略,用于维持FESS的稳定性,从而确保FSSS在电力系统中可靠运行。最后,基于Matlab/Simulink平台搭建了相应的数学仿真模型,以研究系统在多工况下的抗干扰性能。仿真结果表明,所提FSSS在面对不确定性和外部干扰时能够保持稳定运行。所提控制策略为电力系统储能问题提供了可靠的技术支持和解决方案。With the significant increase in power production from wind farms around the world,energy storage systems are needed to dynamically compensate for the intermittency of wind energy and to improve power system stability.To meet the requirements,firstly,the research on flywheel energy storage system(FESS)for doubly-fed motors is carried out with the main idea of twostage static synchronous compensator(SSC)integrated into high-voltage direct current transmission system.Secondly,a virtual impedance voltage-current dual closed-loop control strategy is proposed for maintaining the stability of the FESS in response to the power system voltage fluctuation,load variation and wind resource uncertainty,to ensure FESS reliable operation in the power system.Finally,a corresponding mathematical simulation model is constructed based on the Matlab/Simulink platform to investigate the anti-interference performance of the system under multiple operating conditions.The simulation results show that the proposed FESS can maintain stable operation in the face of uncertainties and external disturbances.The proposed control strategy provides a reliable technical support and solution for power strategy energy storage problems.
