[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.
