电力市场环境下风储联合运行系统的经济效益评估模型

摘要

储能装置与风力发电系统的联合运行已成为解决大规模风电并网的有效手段,基于风力发电特点、风储联合运行系统特性分析,构建了风储联系运行系统收益最大化评估模型。通过算例进行了风速预测准确度和储能容量对系统运行效率及经济效益影响的敏感性分析。研究结果表明,风速预测的高准确度和合理的储能容量能够实现风储联合运行系统最优的经济效益。%The integrated operation of energy storage devices and wind power generation system has become an effective solution to the large-scale grid-connected wind power output.Based on the characteristics analysis of wind power generation and joint operation system of energy storage and wind power,the maximum benefit evaluation model for the joint system is established,combined with the sensitivity analysis of the impact on operation efficiency and economy considering wind speed prediction accuracy and storage capacity.Practical case study results show that accurate wind speed prediction and reasonable storage capacity can improve operation efficiency and economy of the joint operation system.
