Research On Optimal Configuration And Planning Analysis Of Microgrid In Remote Mountain Area

With the increasingly prominent problems of energy shortage and environmental pollution,the country vigorously builds a clean,low-carbon and efficient modern energy system and encourages the use of renewable energy.In recent years,microgrids have developed rapidly.Compared with traditional power grids,microgrids are more complex and uncertain.The rapid development of micro-grid is conducive to the integration and utilization of a variety of distributed energy sources,providing effective solutions to power problems in remote areas,islands,and deserts,and also puts forward higher requirements for the planning and design of micro-grids.At present,the research on microgrid planning mainly focuses on the two hotspots of location planning and constant capacity planning,but there are very few research results and reports on targeted planning considering application areas such as islands and remote mountainous areas.Some results have been achieved in the research on the constant capacity planning of microgrid,but traditional models mostly use single-objective optimization,and only consider environmental protection or economic benefits.The research on the multi-objective optimization configuration of microgrid based on multi-objective particle swarm optimization is relatively less.This paper summarizes and analyzes the basic theories of distribution network planning and multi-objective particle swarm optimization.Based on the characteristics of microgrid in remote mountainous areas,a planning model that considers both economic benefits and power supply reliability is established.Multi-objective optimization of the model is carried out,and a simulation example of Matlab is carried out in a remote mountainous area A,and the fixed capacity configuration scheme of each distributed power supply in the microgrid in this area is given.At the same time,this article summarizes and refines the micro-grid planning and design process,taking Lianzhou City as an example,to analyze the case of micro-grid to solve the grid problem in remote mountainous areas,and finally compare and analyze the advantages of micro-grid in solving grid problem in remote mountainous areas.It has important reference significance for the capacity optimization and planning of microgrid in remote mountainous areas.
