| 摘要: |
| 相邻区域内的微网因互联互供所需可组成多微网系统，有助于提高该区域内微网能效。针对离网模式下串联结构多微网，提出一种综合考虑负荷供电率和负荷持续供电时间的负荷供电性能多目标优化控制算法。建立各层子微网负荷供电性能最优的多目标函数，各层子微网联合进行分布式预测控制，实现滚动优化。算例结果证明，该控制算法实现了多微网负荷供电性能多目标优化。 |

| Abstract: |
| Multi-microgrid system is composed of multiple microgrids in adjacent area to meet the needs of interconnection and power supply, which is conducive to improve the energy efficiency of regional microgrids. Based on off-grid mode multi-microgrid with series structure, this paper comprehensively considers the power supply rate and last supply time of loads and presents a multi-objective optimization control algorithm of loads power supply performance. This paper formulates the multi-objective functions of loads optimal power supply performance in each sub-microgrids. Each sub-microgrids jointly use distributed predictive control to achieve rolling optimization. Under this control algorithm, multi-objective optimization of loads power supply performance of multi-microgrid is verified by actual example. This work is supported by National High-tech R & D Program of China (863 Program) (No. 2014AA052001). |
