【摘要】：随着大型配电网规模的不断扩大,传统的大规模电力系统的弊端逐渐显现出来,越来越难以适应随着人们生活水平提高而提高的高安全性和可靠性的用电需求。在这样的背景下,微电网系统应运而生,微电网系统可作为大电网的一个负荷运行,也可以与大电网断开进入孤岛运行。微电网的应用提高了大电网的运行效率,为传统电网的革新带来了生机。本文在充分调研微电网的研究现状和发展趋势的基础上,研究了基于合同网协议的多代理孤岛微电网系统架构及系统功能,介绍了系统的关键技术,包括多代理系统的特性结构、FIPA规范下的合同网协议以及令牌机制的原理。基于仿真平台CentOS操作系统,采用C++语言设计实现了多代理的孤岛微电网系统,用类之间的相互调用实现Agent之间的通信协作,并运用了多线程技术,使该系统能够在不同时段不同环境下都能达到系统的动态平衡,并可使微电网系统工作在整体效益最大化的状态。由于使用C++中的类来实现,能够很方便地在原有系统基础上增添Agent局部能量控制模块,使系统具有良好的开放性和灵活性。接着研究了微电网的能量协调策略,根据不同的能量管理目标,在微电网系统并网模式下和孤岛模式下,分析对比了三种常见的微电网能量管理策略,重点研究了基于多代理的孤岛微电网多目标优化算法,分析了遗传算法运用在微电网多目标优化中的可行性。今后的研究将是更进一步地丰富和完善基于多代理的孤岛微电网系统功能。改进光伏和风力电源,使其更接近实体电源功能；加入电源建设成本,使用寿命等约束条件,改进效益函数；增加负荷种类,提高系统的实用性等。
[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.
