【摘要】 由于微电网中的微电源和负载具有的波动性和随机性,储能装置是维持微电网安全可靠运行、改善电能质量的关键。分析了超级电容与蓄电池混合储能系统维持微电网的稳定运行适用性,以及当今国内外含混合储能装置的微电网示例。分析比较了几种适合的系统结构和充放电电路,提出了采用F28M35作为中央控制芯片来控制混合储能系统。在Matlab中搭建了仿真模型,验证了所提出的混合储能系统应用于微电网的可行性。

【Abstract】 As both of micro-sources and load are fluctuate and random in micro-grid, energy storage device is the key part to maintain micro-grid operation safely and reliably, also to improve power quality. The applicability of hybrid energy storage system composed of super-capacitors and batteries in the micro-grid was analyzed. In addition, the current hybrid energy storage systems at home and abroad were introduced. Several suitable structures as well as charging and discharging circuits were analyzed and compared, and F28M35x was adopted as the central control chip to control the hybrid energy storage system. At last, a simulation model was built in Matlab to verify the feasibility of the proposed hybrid energy system applied in micro-grid.
