摘要
为定量分析风电接入带来的效益兼顾提高系统的安全性,以系统运行成本最小为主目标,以线路传输安全裕度最大为辅目标,建立微网风电接纳水平多目标优化模型,并采用扩展ε约束法对模型进行求解.实例分析结果表明,所提出的方法可以为微网风电优化提供参考,同时进一步说明储能设备用于提高系统接纳可再生能源的有效性.
To analyze the benefits of wind power access and take into account the safety of the system,a multi-objective optimization model of microgrid wind power accommodation level which takes the minimum operating cost of the system as the main objective and the maximum safety margin of line transmission as the secondary objective is established in this paper.And extendedε-constraint method is used to solve the model.The results of the case analysis show that the proposed method can provide a reference for the optimization of wind power in microgrid.Further,the effectiveness of the energy storage equipment to improve the system accommodation of renewable energy is proved.
