| It is necessary to deepen the study of microgrid planning and design method,which is of great significance to the economic and social benefits.The study of microgrid planning and design method can also to grasp the development direction and raise the quality of microgrid planning and design.Due to the lack of atte ntion to the development of microgrid assistant software both home and abroad,there is limited study of assistant software development.This paper focuses on issues related to the optimal design of microgrid and its assistant software development,corresponding research work as following:1.Overall framework of optimal design for user-side microgrid is built.The whole framework is composed of seven parts: graphical modeling,basic data statistics analysis,timing simulation,capacity optimal configuration,basic electrical calculation,comprehensive indexes evaluation and techno-economic evaluation.2.Microgrid on the user-side is analyzed economically,and a life-cycle investment income model for microgrid is established.On this basis,the method of battery capacity optimization configuration for user-side microgrid is proposed.The optimization model was established with the target of maximizing total net profit and PV consumption rate,considering the isolated island operation requirements,power requirements and battery storage performance constraints.Finally,a NSGA-II algorithm was used to solve the problem and a microgrid with certain configuration is simulated to verify the effectiveness of the model.3.Combining with the client/server structure,the overall architecture of microgrid optimal design assistant software is studied.The research and development of environmental resources,presentation layer,application layer and data layer is described.The development technique is studied,and the research and development scheme is introduced.Description.The system extend application function based on visio secondary development technology.The transmission scheme for database of microgrid optimal design software is studied.All above provide a theoretical basis for the software development based on Visio Drawing Control.Based on all the microgrid optimal design theory study results,microgrid optimal design assistant software is developed.The visual interface simplify the difficulty of the operation of the staffs’ daily work and can greatly save manpower and material resources in the microgrid designing process.The blindness in planning and design could be avoided by selecting some objective for optimization design,and the work efficiency of technical personnel can be improved as well.As an effective techno-economic evaluation tool for microgrid scheme,this software present wide application prospect. |
