中文摘要：

独立型微电网往往包含多种分布式电源和储能装置,协调运行与控制十分复杂,采用不同的控制策略会对其运行工况产生较大的影响。文中充分考虑独立型风光柴储微电网的不同控制策略,计及设备投资成本、运行和维护成本、燃料成本及置换成本,建立了基于不同控制策略的独立型风光柴储微电网优化配置模型,以供电经济性和环保性为优化目标,采用改进型非劣排序遗传算法（NSGA-Ⅱ）寻求优化控制策略下电源类型及其容量的最优配置方案。结果表明该方法可以全面评估不同控制策略对优化配置的作用与影响,以及不同配置方案下的经济性与环保性,从而为用户优化设计提供必要的依据。

英文摘要：

A stand-alone microgrid often contains a variety of distributed generators and energy storage devices,so the coordinated operation and control are very complex.Different control strategies have significant influences on operation conditions.This paper gives full consideration to different control strategies of a stand-alone wind-solar-diesel-battery microgrid.Taking into account the initial cost,the operation and maintenance cost,the fuel cost,and the replacement cost,the optimal sizing model for stand-alone wind-solar-diesel-battery microgrid based on different control strategies is established.With the economical and environmental benefits as the optimization objectives,the non-dominated sorting genetic algorithm（NSGA-Ⅱ） is adopted to seek the optimal sizing scheme for power source types and capacities under the optimal control strategy.The results show that the method can make comprehensive assessment of the role and influence of different control strategies on optimal sizing,as well as the economic and environmental benefits of different schemes.It can clearly serve as a useful tool for optimal microgrid design.
