| 摘要: |
| 规划设计是微电网系统核心技术体系之一。从分布式电源的综合优化(组合优化、容量优化)和分布式电源间的调度优化两个方面对其展开研究。根据分布式电源特性，提出了适用于并网型微电网系统和独立型微电网系统的双层优化规划设计模型。上层优化采用基于NSGA-II的多目标遗传算法计算系统最优配置；下层优化采用混合整数线性规划算法(MILP)计算系统最优运行方案。运用所建立模型，分别针对并网型和独立型微电网系统作了案例计算, 验证了所提方法的正确性。 |

| Abstract: |
| Planning and design for microgrid is one of the key technology. Comprehensive optimization (including combination optimization and capacity optimization) and dispatch optimization for distributed generations (DG) are studied. Based on the characteristics of DGs, a two-stage optimal planning and design model for microgrid is presented, which can apply to both stand-alone microgrid and grid-connected microgrid. For the first stage, multi-objective genetic algorithm based on non-dominated sorting genetic algorithm II (NSGA-II) is used to calculate the optimal system configuration, while the mixed integer linear programming (MILP) is used to deal with the dispatch optimization in the second stage. Using the presented model, a case study is made for stand-alone microgrid and grid-connected microgrid respectively, and the validity of the method is verified. |
