摘要(Abstract)：

配电网运行时需要预留一定的负荷裕度以应对负荷的快速变化。主动配电网由于装设了分布式电源(distributed generation,DG)和储能系统(energy storage system,ESS),使其具备比传统配电网更大的供电能力和更灵活的调节能力。然而,DG出力的波动性使得主动配电的负荷裕度分布不均衡,配电网不能较好地应对负荷波动。建立了一种考虑负荷裕度的主动配电网运行优化混合整数规划模型,该模型以负荷裕度最大为目标,考虑了负荷裕度的均衡分布、潮流约束和拓扑约束。采用修改的IEEE33节点配电系统测试验证了所提模型,结果表明:1)主动配电网的供电能力更强,负荷裕度具备调节能力;2)目标函数考虑负荷裕度均衡分布时,负荷裕度总量相同,而负荷裕度分布更加均衡,其分布方差由0.021大幅度缩小为0.005,较好地提高了配电网应对负荷波动的能力;3)在考虑负荷裕度均衡分布时,ESS紧急负荷补偿能力较不考虑负荷裕度均衡提升2%,ESS的紧急负荷补偿缺额下降6%,抗干扰能力明显提升。
