Research On Smart Control Strategy Of Regional Microgrid And Development Of Key Equipment

With the implementation of the national green sustainable development strategy,low-carbon and environmental protection industries are developing rapidly,such as distributed power,customer-side energy storage,and electric vehicles.In the future,the development of regional micro-grid for users has become an important form of energy utilization,and has become a comprehensive The energy service industry has been concentrating on key areas.Regional energy intelligent control and dispatch management is the focus of research,Because of it is the core competitiveness of regional micro-grid development,and will be the key to safe,stable and reliable operation of the system.This paper will propose regional micro-analysis from the analysis of regional micro-grid networking mode.The typical networking scheme and electrical topology selection of the power grid,the regional micro-grid energy dispatch management strategy and implementation method,it also propose the micro-grid core converter equipment design scheme,the prototype system are designed,and Through hardware equipment system test,it is feasible of verification scheme.the main works of the dissertation are as follows1.Studying on the typical networking scheme of regional micro-grid and the design methods,Proposing the electrical topology and management mode of different subsystems2.Studying on the energy dispatching management strategy and execution method of micro-grid in the region,studies the plug-and-play control mode,and proposes the typical control architecture,control flow,control constraint function and mathematical model3.Studying on the design method of core converter equipment.The design method and typical calculation parameters are given from the aspects of electrical main topology,core component parameter selection and control software design flow4.For the design of the core converter equipment,the experimental platform is built,and the control strategy and protection function are tested and verified.The experimental results prove the feasibility and rationality of the converter equipment design proposed in this dissertation.
