【摘要】：隨著大型配電網規(guī)模的不斷擴大,傳統(tǒng)的大規(guī)模電力系統(tǒng)的弊端逐漸顯現(xiàn)出來,越來越難以適應隨著人們生活水平提高而提高的高安全性和可靠性的用電需求。在這樣的背景下,微電網系統(tǒng)應運而生,微電網系統(tǒng)可作為大電網的一個負荷運行,也可以與大電網斷開進入孤島運行。微電網的應用提高了大電網的運行效率,為傳統(tǒng)電網的革新帶來了生機。 本文在充分調研微電網的研究現(xiàn)狀和發(fā)展趨勢的基礎上,研究了基于合同網協(xié)議的多代理孤島微電網系統(tǒng)架構及系統(tǒng)功能,介紹了系統(tǒng)的關鍵技術,包括多代理系統(tǒng)的特性結構、FIPA規(guī)范下的合同網協(xié)議以及令牌機制的原理�；诜抡嫫脚_CentOS操作系統(tǒng),采用C++語言設計實現(xiàn)了多代理的孤島微電網系統(tǒng),用類之間的相互調用實現(xiàn)Agent之間的通信協(xié)作,并運用了多線程技術,使該系統(tǒng)能夠在不同時段不同環(huán)境下都能達到系統(tǒng)的動態(tài)平衡,并可使微電網系統(tǒng)工作在整體效益最大化的狀態(tài)。由于使用C++中的類來實現(xiàn),能夠很方便地在原有系統(tǒng)基礎上增添Agent局部能量控制模塊,使系統(tǒng)具有良好的開放性和靈活性。接著研究了微電網的能量協(xié)調策略,根據不同的能量管理目標,在微電網系統(tǒng)并網模式下和孤島模式下,分析對比了三種常見的微電網能量管理策略,重點研究了基于多代理的孤島微電網多目標優(yōu)化算法,分析了遺傳算法運用在微電網多目標優(yōu)化中的可行性。 今后的研究將是更進一步地豐富和完善基于多代理的孤島微電網系統(tǒng)功能。改進光伏和風力電源,使其更接近實體電源功能；加入電源建設成本,使用壽命等約束條件,改進效益函數；增加負荷種類,提高系統(tǒng)的實用性等。
[Abstract]:With the continuous expansion of large-scale distribution network scale, the disadvantages of traditional large-scale power system gradually appear. It is becoming more and more difficult to adapt to the demand for high safety and reliability, which increases with the improvement of people's living standard. In this context, microgrid systems emerge as the times require, and microgrid systems can be used as a load of large power grids. The application of microgrid can improve the operation efficiency of large power grid and bring vitality to the innovation of traditional grid. Based on the research status and development trend of microgrid, this paper studies the architecture and system function of multi-agent isolated island microgrid system based on contract net protocol, and introduces the key technology of the system. It includes the characteristic structure of multi-agent system and the principle of contract network protocol and token mechanism under FIPA specification. Based on CentOS operating system, a multi-agent islanding microgrid system is designed and implemented by C language. The communication and cooperation between Agent are realized by calling each other among classes, and multithreading technology is used to make the system achieve dynamic balance in different time and different environment. It can make the microgrid system work in the state of maximizing the overall benefit. Because of using the class in C to realize, it is convenient to add the Agent local energy control module to the original system. The system has good openness and flexibility. Secondly, the energy coordination strategy of microgrid is studied. According to different energy management objectives, in grid-connected mode and islanding mode of micro-grid system, Three common microgrid energy management strategies are analyzed and compared. The multi-objective optimization algorithm based on multi-agent is studied, and the feasibility of genetic algorithm in micro-grid multi-objective optimization is analyzed. The future research will further enrich and improve the functions of the island microgrid system based on multi-agent, improve the photovoltaic and wind power supply, make it closer to the physical power supply function, add the power construction cost, service life and other constraints. Improve benefit function, increase load category, improve system practicability and so on.
