摘要

风速的变化会改变风能转换系统的输出功率。在直流微电网中，WECS系统通过DC-DC升压变换器与直流链路连接，导致直流链路电压变化较大。保持直流链路电压恒定是一个具有挑战性的问题。在风速变化较大的情况下，复合储能系统(CESS)可以稳定直流链路电压。同样，在阵风期间，CESS通过超级电容器吸收系统的瞬态能量来保持直流链路电压恒定。本文提出了一种基于wcs的CESS电源管理算法。电源管理算法保持了超级电容器和电池的SoC限制。在MATLAB-Simulink中对系统进行仿真，验证结果。

Design of Composite Energy Storage System for Wind Turbine under Gust

The variation in wind speed changes the output power of Wind Energy Conversion System (WECS). In DC microgrid, the WECS system connected to DC link through DC-DC boost converter results in large variation in DC link voltage. Maintaining the DC link voltage constant is a challenging issue. Under wide variation of wind speed, the Composite Energy Storage System (CESS) can stabilize the DC link voltage. Similarly, during the gust period, the CESS maintains the DC link voltage constant by supercapacitor absorbing transient energy from the system. In this paper, a power management algorithm for WECS based CESS is proposed. The power management algorithm maintains the SoC limits of both supercapacitor and battery. The simulation of the system carried out in MATLAB-Simulink to validate the results.
