【摘要】：隨著世界經(jīng)濟的迅速發(fā)展,社會的不斷進步,工業(yè)生產(chǎn)尤其是重工業(yè)生產(chǎn)迅速發(fā)展使得電力需求量逐漸增大,帶動了傳統(tǒng)大規(guī)模集中式電網(wǎng)的迅速發(fā)展。另一方面隨著世界能源的日趨枯竭、環(huán)境的惡化,以光伏、風力為主的新能源和分布式能源引起了各國政府的普遍關(guān)注。隨著分布式能源接入的規(guī)模和數(shù)量不斷增加,越來越多的問題暴露出來。以分布式發(fā)電電源為主體的微電網(wǎng)系統(tǒng)逐漸發(fā)展起來成為近來研究的熱點問題。 本文主要針對微電網(wǎng)的Multi-Agent體系進行架構(gòu)設計,詳細介紹了模式控制器結(jié)構(gòu)設計、工作原理,引入了Energy-HUB作為微電網(wǎng)能量集散中樞和穩(wěn)定控制單元。針對微電網(wǎng)的被動式離網(wǎng)工作模式進行了重點研究,主要針對微電網(wǎng)被動式離網(wǎng)模式切換過程進行了探討。微電網(wǎng)的模式轉(zhuǎn)換分為離網(wǎng)動作和以微源重組為主的網(wǎng)絡資源重組兩部分。由于被動式離網(wǎng)事件發(fā)生較為突然,模式切換過程要求時間較短。針對模式切換的整體動作本文以Petri網(wǎng)為核心通過讀取狀態(tài)元件表的方式實現(xiàn)對網(wǎng)絡的操作。在針對資源重組的研究中本文綜合考慮模式切換的快速性、經(jīng)濟性和穩(wěn)定性對果蠅尋優(yōu)算法和粒子群算法通過算例模型和實際數(shù)據(jù)對其進行仿真綜合對比,最終發(fā)現(xiàn)果蠅算法更加實用于微電網(wǎng)的模式切換過程。最后本文對全天24個時段進行極限情況模式切換仿真,通過得到的各個Agent單元的重組方案結(jié)果可以看出包含分布式光伏和風力的微電網(wǎng)的經(jīng)濟實用價值較高。
[Abstract]:With the rapid development of the world economy and the continuous progress of the society, the rapid development of industrial production, especially heavy industry, makes the demand for electricity increase gradually. Has driven the rapid development of traditional large-scale centralized power grid. On the other hand, as the world's energy is increasingly depleted, the environment is deteriorating, to photovoltaic, New and distributed sources of energy, mainly wind power, have attracted widespread attention from governments all over the world. With the increase in the scale and number of distributed energy access, More and more problems are exposed. The microgrid system with distributed generation source as the main body has gradually developed into a hot topic in recent research. In this paper, the Multi-Agent architecture of microgrid is designed, and the structure design and working principle of the mode controller are introduced in detail. Energy-HUB is introduced as the energy distribution center and stability control unit of microgrid. The passive off-grid operation mode of microgrid is studied in detail. This paper mainly discusses the switching process of passive off-grid mode in microgrid. The mode conversion of microgrid is divided into two parts: off-grid action and recombination of network resources, which are mainly composed of micro-source recombination. The mode switching process requires a short time. In this paper, the Petri net is used as the core to realize the operation of the network by reading the state element table. In the research of resource reorganization, this paper considers comprehensively the operation of the network. The rapidity of mode switching, The economics and stability of the optimization algorithm and particle swarm optimization algorithm of Drosophila were simulated and compared by the example model and the actual data. Finally, it is found that Drosophila algorithm is more applicable to the mode switching process of microgrid. The results of each Agent unit reorganization scheme show that the microgrid with distributed photovoltaic and wind power is of high economic and practical value.
