| 摘要: |
| 微电网系统的优化运行应考虑经济性、环保性、可靠性以及对可再生能源的响应特性等多方面因素。以电池储能系统（BESS）为研究对象，提出一种基于动态规划的多目标优化方法，以最优化经济效益、最大化可靠性、最小化可再生能源功率波动、最符合可再生能源发电计划作为微电网优化运行的目标，应用模糊理论和二元对比定权法将其转化为单目标优化问题，从而获得BESS的动态最优调度策略。算例表明，该方法具有良好的优化效果。 |

| Abstract: |
| Multiple factors，such as economy，environmental protection，reliability and renewable energy response characteristics，should be considered in the optimal microgrid operation. A method of multi-objective optimization based on the dynamic dispatch of BESS（Battery Energy Storage System） is proposed for optimal microgrid operation，which takes the best economic benefit，maximum reliability，minimum renewable energy power fluctuation and finest accordance with renewable energy generation schedule as its objectives. The fuzzy theory and dualistic factor contrast method are applied to convert it into a single objective optimization problem for achieving the optimal dynamic dispatch strategy of BESS. Results of case study show that，the proposed method has excellent optimization effect. |
