摘　　要：以提升碳削减量、降低大电网的碳排放量为前提,同时保证配电网的稳定运行和电能供应,为此研究基于免疫萤火虫算法的低碳主动配电网扩展规划模型。以碳排放量和经济总代价最小为依据,构建主动配电网扩展规划的目标函数,并设定网络中节点有功和无功2种功率的平衡和电压、线路电流、分布式电源容量的约束条件;基于免疫萤火虫算法,优化求解构建的目标函数,获取最优低碳主动配电网扩展规划结果。测试结果显示:迭代次数达到120次以后,模型即可完成收敛求解;生成扩展规划后的配电网各个线路和节点结构,规划后配电网中各个节点电压最大波动值为12.4%,碳排放量的最大值为1.77×10^(6) t,碳削减量的最高比例为27.6%,配电网网损最大值为66.4 kW,同时可保证配电网良好的自治性,且应用性良好。In order to improve the carbon reduction,reduce the carbon emissions of large power grid,and ensure the stable op-eration of distribution network and power supply,a low carbon active distribution network expansion planning model based on immune firefly algorithm is studied.Based on carbon emissions and economic minimum total cost.This paper constructs the objective function of the active power distribution network expansion planning and set constraints of balance and voltage,line current,distributed power supply capacity in the network node active and reactive power.Based on immune to firefly algo-rithm.This paper optimizes and solve the objective function,to obtain the optimal results low carbon active distribution net-work expansion planning.The test results show that the convergence solution can be completed after the number of iterations reaches 12o.This paper generates each line and node structure of distribution network after expansion planning.After plan-ning,the maximum voltage fluctuation value of each node in distribution network is 12.4%,the maximum carbon emission is 1.77 ×10^(6)t,the highest proportion of carbon reduction is 27.6%,and the maximum loss of distribution network is 66.4 kW.Meanwhile,good autonomy of distribution network and good application can be ensured.
