| 摘要: |
| 分析了微电网孤岛系统稳定运行、能量供求平衡的机理和常规的微电网孤岛能量管理控制策略，提出一种新型超级电容与蓄电池混合储能系统的功率自适应控制策略， 通过对混合储能系统进行上层的能量管理控制，使超级电容和蓄电池输出功率得到合理分配，以满足微电网孤岛运行时的电能质量要求和负荷的功率需求，并且能够提高系统全寿命周期经济性。最后建立了微电网孤岛系统的仿真模型，利用PSCAD／EMTDC仿真验证了所提策略的有效性，该控制策略优化了蓄电池的工作过程，延长了蓄电池使用寿命，并且不需要数据采集和通信环节，提高了微电网孤岛系统运行的可靠性和稳定性。 |

| Abstract: |
| The stable operation and energy balance of islanded microgrid and its traditional energy management strategy are analyzed and a strategy of adaptive power control is proposed for its hybrid battery-supercapacitor storage system. In order to meet the requirements of islanded microgrid for both power quality and load and enhance the system economics over lifetime，the output power of hybrid battery-supercapacitor storage system is reasonably allocated between supercapacitor and battery by its high-level energy management. A PSCAD／EMTDC model of islanded microgrid is built to verify the validity of the proposed strategy，which optimizes the working process of battery，prolongs its service life，cancels the data collection and communication and improves the operational reliability and stability of islanded microgrid. |
