摘要
输电网络扩展规划问题是一个复杂的组合优化问题。蚁群算法是用于解决组合优化问题的一种高效的随机化内启发式全局搜索技术。文中结合单阶段输电网络扩展规划问题的特点,应用改进的蚁群算法来解决输电网络扩展规划问题,建立了相应的数学模型,并给出求解算法。2个算例系统的计算结果表明了这种方法可有效减小搜索空间,并具有计算速度快和收敛性好等优点。
Transmission network expansion planning(TNEP)is a complex combinatorial optimization problem.Although this problem has been extensively studied,it is still not well solved.In recent years,a new meta-heuristic method,ant colony algorithm,is emerging.It is highly efficient for quickly finding high quality solutions to combinatorial optimization problems.In this paper,an improved ant algorithm is introduced to the transmission network expansion planning,and the corresponding mathematical model,together with its solution algorithm,is also presented.The simulation results for two sample systems,although preliminary,show its advantage on computing speed and convergence.
