摘要
针对含风力发电、光伏发电和铅酸电池储能的独立型微电网,从用户效益角度出发,提出了计及初始投资成本、置换成本、运行维护成本等经济因素的优化配置模型。考虑独立型微电网运行约束条件,采用含整数变量的混合十进制遗传算法对模型求解,得出微电网分布式电源和储能系统的容量最优配置。以江西南昌实际风光历史数据为例,算例验证了所提优化配置策略的有效性与准确性,并分析了不同单元价格对优化配置策略的影响。
This paper proposed an optimal configuration model that considers the initial investment cost,replacement cost,operation and maintenance cost and other economic factors for the islanded micro-grid with wind energy,photovoltaic power generation and lead-acid battery energy storage.Considering the constraints of the independent micro-grid operation,a mixed decimal genetic algorithm with integer variables was used to solve the model,and the optimal configuration of the micro-grid distributed power supply and energy storage system was obtained.Taking the historical data of Nanchang in Jiangxi as an example,it verifies the validity and accuracy of the optimal configuration strategy proposed in this paper,and analyzes the influence of different unit prices on the optimal configuration strategy.
