摘　　要：针对微电网中太阳能光伏发电、风力发电等分布式发电的特点,考虑到不同类型、容量的微电源所消耗的燃料、效率、运行和维护费用、微电网与主电网功率交互价格、有害气体的排放量不同以及太阳能光伏发电、风力发电的特殊性提出了一种综合考虑发电成本与排放成本的微电网环保经济调度的数学模型。对发电成本与排放成本的不同权重采用改进遗传算法对其进行数值求解,并通过算例验证了所建立的模型与优化算法的有效性与合理性。According to the characteristics of distributed generation in microgrid, such as solar photovohaic power generation and wind power generation, and considering the fuels, the efficiency, the operation and maintenance costs consumed by different micro power sources, the price of power between main grid and microgrid, the emission level of harmful gas, the particularity of solar photovoltaic power generation and wind power generation, a novel mathematical model of environmental - protection and economic dispatch of grid - connected microgrid is presented considering power generation cost and emission cost. Based on the calculation of the different weights of power generation cost and emission cost by genetic algorithm, the simulation results show the validity and rationality of the established model and the optimal algorithm.
