摘要
风光储发电系统与混合储能系统的结合能够进一步提高系统的综合效率。为此,本文提出一种结合混合储能技术(锂电池和超级电容)、可再生能源综合利用技术(太阳能和风能利用)的风光储联合发电系统。针对性提出超级电容荷电状态二次反馈的混合储能控制策略。以系统年综合成本最小为优化目标,以本文新提出的结合人工鱼群算法的模拟退火算法为优化工具,对系统进行配置优化。研究结果表明该系统的年综合成本2.7×10^(6)元。
The coupling of hybrid energy storage technology and wind-solar-storage hybrid generation system can further improve the overall performance of the power generation system.Therefore,this article proposes a wind-solar-storage hybrid generation system that combines hybrid energy storage technology(lithium batteries and supercapacitors)and comprehensive renewable energy utilization technology(solar and wind energy utilization).The control strategy of low pass filter combined with secondary feedback of ultracapacitor is proposed for the system.And the system configuration is optimized with the goal of minimizing the annual comprehensive cost of the system.The research results show that the annual comprehensive cost of the system is 2.7×10^(6) CNY.
