为提高混合储能系统对直流微电网母线功率支撑的双向调控性能，针对混合储能系统，提出一种基于非奇异终端滑模自抗扰技术的双向功率控制方法。分析建立采用双向半桥DC/DC变换器的并网接入系统数学模型;设计超级电容端电压稳定附加功率补偿控制结构;利用基于趋近律的非奇异终端滑模自抗扰技术和基于扩张状态观测器的系统不确定及扰动项在线估计，设计混合储能双向功率调节非线性控制器。通过仿真测试，并与传统线性控制器性能对比，验证所提方法的正确有效性。
POWER CONTROL FOR HYBRID ENERGY STORAGE SYSTEM BASED ON TERMINAL SLIDING MODE AUTO-DISTURBANCE REJECTION
In order to improve the bidirectional control performance of the hybrid energy storage system(HESS)on the power support of the DC microgrid bus,a bidirectional power control method based on the terminal sliding mode auto disturbance rejection control(NTSM-ADRC)is proposed for the hybrid energy storage system.The mathematical models of the grid-connected system and bidirectional half-bridge DC/DC converter was analyzed.An additional power compensation control structure for the voltage stabilization of the supercapacitor was designed.Using non-singular terminal sliding mode auto-disturbance rejection control based on reaching law approach,and online estimation of system uncertainty and disturbance terms based on extended state observer,a bidirectional power regulation nonlinear controller for hybrid energy storage was designed.Through the simulation experiments and the performance comparison with the traditional linear controller,the simulation results verify the correctness and effectiveness of the proposed method.
