【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.更多还原
