摘要
为了确保微电网系统的电能质量和稳定运行,提出基于Benders分解的微电网储能容量优化配置算法.以微电网系统作为研究对象,分析不同储能单元的充放电特性,将储能系统全寿命周期最小成本作为目标函数,组建微电网储能容量优化配置模型.根据模型特点,将模型分解为上下2 层子模型,通过Benders分解算法对模型求解,进而获取最优微电网储能容量优化配置方案.经实验测试结果表明,所提算法可以更好完成容量优化配置,经过优化配置后,电网功率波动范围得到了明显降低.
Abstract
In order to ensure the power quality and stable operation of microgrid system,this paper presented an Optimal configuration algorithm of energy storage capacity in microgrid based on Benders decomposition.Based on the microgrid system,the charge and discharge characteristics of different energy storage units were analyzed at first.And then,minimum cost of life cycle of the energy storage system was taken as the objective function.Meanwhile,an opti-mal configuration model of microgrid energy storage capacity was built.According to the characteristics,the model was divided into two sub models.Finally,Benders decomposition algorithm was adopted to solve the model,thus obtaining the scheme about optimal configuration of microgrid energy storage capacity.The experimental results show that the proposed algorithm can complete the optimal configuration of capacity splendidly.After the optimal configuration,the power fluctuation range of power grid is significantly narrowed.
