摘要
为了使得区域内分布式储能系统保持电能均衡,文中提出了一种基于成本收益分析的微电网(MG)储能系统优化配置方法。分别建立了孤岛模式和并网模式下MG的分布储能系统(DESS)最佳储能容量数学模型,最终将其转化为混合线性整数问题(MLIP),结合数学规划的建模语言(AMPL)进行求解。通过实例分析结果表明:所提出的方法在孤岛模式和并网模式下均可以确定DESS的最佳储能容量,且并网模式下安装DESS可增加MG的总收益,孤岛模式下安装DESS可减小MG的总成本。
In order to keep the energy balance of distributed energy storage system in the region,a cost-benefit analysis based optimal allocation method for microgrid(MG)energy storage system is presented in this paper.The mathematical models of optimal storage capacity of MG distributed energy storage system(DESS)under islanding mode and grid-connected mode are established respectively.Finally,the model is transformed into mixed linear integer problem(MLIP)and solved with mathematical programming modeling language(AMPL).The analysis results show that the proposed method can determine the optimal energy storage capacity of DESS in both island mode and grid-connected mode,and installation of DESS in grid-connected mode can increase the total benefit of MG,while installation of DESS in island mode can reduce the total cost of MG.
