| 摘 要： | 为解决电力系统中的经济负荷分配问题，提出一种将约束优化与粒子群优化算法相结合的混合算法，同时引入直接搜索方法。使得混合后的粒子群优化算法不但具有高效的全局搜索能力，而且具有较强的局部搜索能力，避免陷入局部最优，提高求解精度。对两个实例进行测试，与其他智能算法的结果比较，证明提出的算法可以有效找到可行解，避免陷入局部最优，实现问题的快速求解。

| Abstract: | The Hybrid Particle Swarm Optimization(HPSO) algorithm is proposed for solving the Economic Load Dispatch(ELD) problems of power system.The HPSO combines the particle swarm optimization with constraint optimization and direct search.The HPSO has the effective global search ability and local search ability to avoid trapping local optimal.To verify the effectiveness of the proposed algorithm,the HPSO is tested and the obtained results are compared with those obtained by other approaches.Experi-ment results show that with the proposed algorithm feasible solutions can be effectively found,local optimal can be avoided and the fast solution of ELD can be implemented. |
