摘　　要：基于人工免疫算法借鉴生物免疫系统中抗体多样性的保持机制和基于抗体浓度的调节机制,同时又具有一般进化算法的随机全局搜索能力,适合求解多目标问题的特点,综合考虑配电网供电可靠性对用户侧的经济影响,提出了应用免疫算法求解考虑用户侧停电损失的配电网网架规划问题的优化方法。针对配电网辐射性的要求,根据图论知识,采用将新增加负荷节点作为染色体基因座的编码方法,保证了生成解的可行性,避免了辐射性检查,提高了计算速度。最后通过实际算例说明了这种方法的有效性。The artificial immune algorithm (AIA ) draws into the immune diversity and antibody's density mechanism to maintain the individual's diversity and remains evolution algorithm's global stochastic searching ability, so it's adopted to solve multi-objective problems.Considering the influence of distribution system reliability on economic value on consumer side, a new mathematical model with comprehensive consideration of investment, operation and loss of the consumer caused by power failure is presented in this paper. AIA is applied to distribution network structure planning with such a mathematical model. Also, a novel chromosome coding strategy based on graph theory is proposed to ensure that all the randomly generated chromosomes are feasible. The effectiveness of the model and algorithm is verified with calculations.This project is supported by Henan Province Technologies R&D Program(No.0324250075).
