【摘要】：开展和深入微电网规划设计方法的研究,对于提高微电网规划水平、把握微电网发展方向、提高经济和社会效益具有重大的理论与现实意义,同时,目前的科研工作缺乏对微电网辅助软件研发的关注,国内也尚没有出现商业化的关于微电网规划设计的成熟软件。本文就此展开研究,论文所做的工作为:1.建立了用户侧微电网规划设计整体框架,框架中包括图形化建模,基础数据统计分析,时序状态仿真,容量优化配置,基本电气计算,综合评价指标和技术经济评价等部分。2.对用户侧微电网进行了经济性分析,建立了全生命投资收益模型。在此基础上提出了用户侧微电网储能优化配置方法。建立了基于总净利润最大化和光伏消纳最大化的双目标优化模型,构建了孤岛运行保障,光伏自消纳率和储能性能等约束条件,采用NSGA-II算法对模型进行求解,并对某一确定配置微电网进行了时序状态仿真分析,验证了在微电网优化运行策略下模型的有效性。3.结合三层客户机/服务器架构研究了微电网规划设计软件的总体架构设计。阐述了软件中环境资源,表示层,应用层和数据层的研发。研究了软件所用的开发技术,介绍了软件的研发方案,研发平台依托Visio进行二次开发,在其基础上拓展实现微电网规划设计的相关功能。并研究了软件的数据库传输方案,为软件系统的二次开发提供了良好的理论基础。最后结合上述微电网规划设计方法理论研究成果,实现了微电网规划设计软件的开发。该软件以可视化的操作界面实现优化设计工作的程序化、自动化,能够有效减少优化设计人员的工作量、提高优化设计工作效率,实现规划设计工作的优化合理。
[Abstract]:The research of microgrid planning and design method is of great theoretical and practical significance for improving the level of microgrid planning, grasping the development direction of microgrid, and improving economic and social benefits, at the same time, At present, the research work lacks the attention to the research and development of microgrid auxiliary software, and there is no commercial mature software for microgrid planning and design in China. In this paper, the work of this paper is: 1: 1. The overall framework of planning and design of user-side microgrid is established, which includes graphical modeling, statistical analysis of basic data, time series state simulation, capacity optimization, basic electrical calculation, comprehensive evaluation index and techno-economic evaluation. The economic analysis of user-side microgrid is carried out, and the whole life investment income model is established. On the basis of this, a method of optimal configuration of energy storage in user-side microgrid is proposed. A two-objective optimization model based on the maximization of total net profit and photovoltaic absorption is established, and the constraints such as island operation guarantee, photovoltaic self-absorption rate and energy storage performance are constructed. NSGA-II algorithm is used to solve the model. The time series state simulation analysis of a certain microgrid is carried out, which verifies the validity of the model under the optimal operation strategy of microgrid. Based on the three-tier client / server architecture, the overall architecture design of microgrid planning and design software is studied. The research and development of environment resource, presentation layer, application layer and data layer in software are expounded. This paper studies the development technology used in the software, and introduces the research and development scheme of the software. The research and development platform relies on Visio for secondary development, on the basis of which the related functions of microgrid planning and design are expanded and realized. The database transmission scheme of the software is studied, which provides a good theoretical basis for the secondary development of the software system. Finally, the development of microgrid planning and design software is realized based on the theoretical research results of the microgrid planning and design method mentioned above. The software realizes the programming and automation of the optimization design by visual operation interface, which can effectively reduce the workload of the optimization designer, improve the efficiency of the optimization design, and realize the optimization of the planning and design work reasonably.
