设计了基于2种直流功率变换器的蓄电池-超级电容器并联控制系统，针对混合储能系统充放电过程具有非线性、时变性、滞后性的特点，提出了一种基于模糊算法的储能系统优化控制策略，并在MATLAB/Simulink进行了建模和仿真。仿真和实验结果表明采用新型的控制策略，不仅能够在保持直流母线电压稳定的同时提高储能系统的功率输出能力，而且有效改善传统算法控制中极易产生系统振荡的弊端，优化蓄电池的工作过程从而延长其寿命。

Parallel control system for battery-super capacitors is designed based on the two kinds of power converter. And a kind of energy storage system optimization control strategy based on fuzzy algorithm is also put forward for the characteristics of nonlinear, time-varying, hysteresis in the charge and discharge process of hybrid energy storage system. Then its modeling and simulation is finished in MATLAB/Simulink. Simulation. Experimental results show that with the new control strategy the power output of energy storage system is improved and stability of DC bus voltage is maintained. In addition, the disadvantages of oscillation produced easily in the traditional algorithm of control system is effectively improved and the working process of the storage batteries is optimized thatis good for ex-tending its life.
