| 摘要: |
| 针对输电网规划求解中存在变量多、维数高、约束条件复杂等导致难以求得全局最优解的问题，将蝙蝠算法应用于输电网规划求解当中。为避免原算法精度低、易陷入局部最优的缺点，提出在原算法基础上，通过逻辑自映射函数产生混沌序列对蝙蝠前n%适应度最优个体进行混沌优化，并建立计及线路建设费用、网损费用、输电线路走廊建设费用、N及N-1约束条件下的过负荷惩罚费用为目标函数的输电网规划模型。最终通过Matlab软件对IEEE-18和巴西南部46节点标准算例编程计算，结果验证了新算法在求解大维度输电网规划模型的可行性及高效性。 |

| Abstract: |
| In allusion to diificult to obtain the global optimal solutions due to the problems of much variables, high dimensions and sophisticated conditions in solving transmission network planning, bat algorithm is applied. The modified bat algorithm is proposed to solve low precision and local optimal solution of original algorithm through optimization of the fitness optimal individuals of bat first n% fitness by chaotic sequences generated by self-logical function. Power network planning model is designed and constructed which takes line investment cost, overload cost of normal operation, transmission corridor cost, and N and N?1 overload penalty cost constraints as objectives. By testing node IEEE-18 and Southern Brasilian 46-bus system with Matlab, the results show that the new method is feasible and efficient to solve transmission model of large dimension power transmission grid. |
