英文摘要： How to scientifically carry out the optimal planning for stand-alone microgrid system is the key issue for ensuring reliable and economic operation of the microgrid. Focusing on the problem, this project from the point of view of the stand-alone microgrid system optimal goals, fully takes into account the uncertain of load, renewable energy resources and market environment, the diversity of distributed generation energy supply system operational characteristics, and the complexity of the stand-alone microgrid system advanced energy management strategies. Based on the above considerations, using uncertain mathematical programming theory and reliability analysis theory, the project researches on the integrated energy optimal planning methods of the stand-alone microgrid system in an uncertain environment, the reliability assessment methods of the stand-alone microgrid system and the solutions to improve the system reliability, the uncertain double-layer optimal planning methods of the whole stand-alone microgrid system, and establishes the mathematical models of the optimal planning. The project will ultimately get a design of the stand-alone microgrid system planning including distributed generation energy supply system, which can meet the user needs of multiple energy sources such as cold, heat, electricity and
