摘　　要：随着能源危机和环保问题的日益严重,以风能为代表的新能源发电技术快速发展。本文以包含风电和储能的微网为对象,研究离网模式下储能容量的配置问题。为同时保证离网型风储微网的供电可靠性和风能利用率,提出了能量不平衡率的概念。同时考虑风电出力与负荷变化规律的相关性,研究能量不平衡率和相关性对储能容量的影响。最后在具体微网条件下,以能量不平衡率为约束,以系统综合成本最低为目标配置了储能容量。With the energy crisis and environmental problems becoming more and more serious, the renewable energy represented by wind energy is developed rapidly. In this paper, the capacity configuration of energy storage in islanded mode with the microgrid containing wind power and energy storage is studied. In order to ensure the power supply reliability of islanded wind-storage microgrid and the utilization ratio of wind energy, the rate of energy imbalance is proposed. Considering the correlation between wind power and load, the influence of the rate of energy imbalance and correlation on energy storage capacity is studied. Finally, under the specific microgrid conditions, the energy storage capacity is configurated with the rate of energy imbalance as the constraint and the lowest comprehensive cost as the objective.
