| 摘 要： | 在详细介绍了实行厂级负荷优化分配的重要性后,着重论述了用于火电厂厂级负荷优化分配的一般动态规划算法并指出其不足,提出了一种改进的动态规划算法,它根据经验所形成的策略来变换步长,再对不同步长下的所求解进行二次寻优,基本上克服了因步长选取不当而带来的非最优化问题.案例表明：改进型动态规划算法效果良好,具有不错的工程应用价值.

| Abstract: | With the detailed analysis of the importance of implementing optimal load distribution in power plants,this paper emphatically discusses a generic dynamic programming(DP) method applied in optimal load distribution in thermal power plants.After its deficiency is pointed out,an improved DP method is proposed,which changes step length according to experienced-based strategies,and conducts secondary optimization on the solution under different step length,so as to basically overcome the problem of no optimization brought by the step length selected irrelevantly.The good effect of the proposed method has been proved by the case in this paper;it has good applicable value in projects. |
