【摘要】：在能源危機和環(huán)境危機的雙重威脅下,能源互聯(lián)網(wǎng)的概念應(yīng)運而生,并迅速成為各國爭相發(fā)展的熱點。在此背景下,電池儲能系統(tǒng)作為能源互聯(lián)網(wǎng)中必不可少的設(shè)備,其發(fā)展空間不可限量�，F(xiàn)在常用的電池儲能系統(tǒng)規(guī)模較小,遠遠不能滿足能源互聯(lián)網(wǎng)的使用需求,因此大規(guī)模電池儲能系統(tǒng)的出現(xiàn)和發(fā)展也就成為了必然。但是目前的大規(guī)模電池儲能系統(tǒng)仍然面臨著使用壽命短、工作效率低、可靠性差等一系列問題,因而人們迫切需要掌握大規(guī)模電池儲能系統(tǒng)的設(shè)計和管理技術(shù)。鑒于此,本文主要圍繞大規(guī)模電池儲能系統(tǒng)的拓撲結(jié)構(gòu)設(shè)計和能量管理優(yōu)化問題展開研究。首先,通過對單體鋰離子電池進行充放電特性實驗,掌握鋰離子電池的使用特性,為鋰離子電池儲能系統(tǒng)的優(yōu)化設(shè)計和能量管理提供必要的理論依據(jù)。其次,對電池組內(nèi)電池的各種連接方式進行詳細的介紹并分析各種結(jié)構(gòu)方式對電池組性能的影響,在指出現(xiàn)有的電池儲能系統(tǒng)拓撲結(jié)構(gòu)的不足之后,考慮模塊化設(shè)計的優(yōu)點,采用分組、分層次、獨立自治的設(shè)計理念對大規(guī)模鋰離子電池儲能系統(tǒng)的拓撲結(jié)構(gòu)進行科學(xué)的設(shè)計。然后,重點分析放電深度和放電倍率對鋰離子電池使用壽命的影響,針對本文設(shè)計的大規(guī)模鋰離子電池儲能系統(tǒng)建立基于電池模組SOC的放電效率優(yōu)化模型,并基于上述壽命影響分析和效率優(yōu)化模型給出電池儲能系統(tǒng)的放電管理策略,從而實現(xiàn)系統(tǒng)的高效長壽命穩(wěn)定運行。最后,建立仿真算例,運用遺傳算法對算例中鋰離子電池儲能系統(tǒng)的放電效率優(yōu)化模型進行求解,并對優(yōu)化的效果進行對比分析。此外,在文章的結(jié)尾處對全文的主要研究內(nèi)容進行了歸納總結(jié),并對進一步的研究和改進工作進行了展望。
[Abstract]:Under the dual threat of energy crisis and environmental crisis, the concept of energy Internet has emerged as the times require, and has rapidly become a hot spot in the development of various countries. In this context, battery energy storage system as an essential equipment in the energy Internet, its development space is unlimited. The commonly used battery energy storage system is small and can not meet the needs of the energy Internet, so the emergence and development of large-scale battery energy storage system has become inevitable. However, the current large-scale battery energy storage system still faces a series of problems, such as short service life, low working efficiency, poor reliability and so on. Therefore, people urgently need to master the design and management technology of large-scale battery energy storage system. In view of this, this paper focuses on the topology design and energy management optimization of large-scale battery energy storage system. First of all, through the charge and discharge characteristics of the lithium ion battery, we can master the characteristics of the lithium ion battery, and provide the necessary theoretical basis for the optimization design and energy management of the energy storage system of the lithium ion battery. Secondly, the various connection modes of the battery pack are introduced in detail and the influence of various structure on the performance of the battery pack is analyzed. After pointing out the shortcomings of the topology structure of the existing battery energy storage system, the advantages of modularization design are considered. The topological structure of large scale lithium ion battery energy storage system is designed scientifically by using the concept of grouping, hierarchical and independent autonomy. Then, the influence of discharge depth and discharge rate on the service life of Li-ion battery is analyzed, and a discharge efficiency optimization model based on battery module SOC is established for the large scale Li-ion battery energy storage system designed in this paper. Based on the above life impact analysis and efficiency optimization model, the discharge management strategy of battery energy storage system is given, so as to realize the stable operation of the system with high efficiency and long life. Finally, a simulation example is established, and the optimization model of discharge efficiency of Li-ion battery energy storage system is solved by genetic algorithm, and the effect of optimization is compared and analyzed. In addition, at the end of the article, the main research contents are summarized, and the further research and improvement work is prospected.
