摘　　要：采用时序性聚类分析法将气象数据划分为合适的场景数,依据各场景气象数据在箱线图中的分布状况拟合相应的数学函数来确定各场景24h气象数值,以精简数据、减少计算量、保持优化结果的客观性。以寿命周期内各类微电源的投资和安装费用、运行和维护费用、废弃后拆卸和治污费用、排污惩罚费用、燃料费用、停电赔偿费用以及能量过剩惩罚费用为基础,建立微网成本数学模型;以分布式能源发电的碳贸易收益、并网收益、环保收益为基础,建立微网收益数学模型;通过对微网成本和收益的整合,建立微网孤网的水平年静态成本-收益数学模型。在计及能量过剩及缺额的孤网能量控制策略下,利用遗传算法优化孤网的容量配置,并通过算例验证了模型和算法的合理性。This paper uses timing resistance clustering analysis to divide the scene number of natural data, then based on box plot to confirm the appropriate mathematical function to determine the 24 hour date of each scene, in order to streamline data, reduce the amount of computation, keep the objectivity of the optimization results. Based on investment and installation costs of various types of micro-power, run and maintenance costs, disassembly and pollution control costs after they be abandoned, punitive costs of discharge pollutants, fuel costs, compensatory damages of power cut and penalty costs of excess energy, build the cost mathematical model of micro-grid; according the carbon trade income of distributed energy resources, connect the grid income, environmental protection income to establish its income mathematical model; through comprehensive calculation of costs and benefits, the static cost-benefit model of island micro-grid based on the level of years is established. Put forward the energy control strategy of the grid independent operation in the case of energy excess or deficiency, uses genetic algorithm in that condition to determine the configuration of micro-grid and verify the rationality of the model and algorithm by the example.
