摘要
水电站厂内机组间的发电流量分配是水电站经济运行中的一个重要混合非线性优化问题。文章设计了一种逐次逼近动态规划法,可用于求解水电机组的组合问题。该算法可有效地减少状态变量的个数,且能收敛到满意解。通过实例研究,验证了模型合理性和算法的可行性与有效性。
The outflow allocation among the hydropower units is an important non-l inear optimization problem in the hydroplant economical operation. In this paper , a DP with successive approximation method is designed for solving the hydropow er unit commitment problem. The algorithm can effectively reduce the number of s tate variables, and converge to the optimal solution. With a case study, the mod el is tested reasonable, and method feasible and efficient.
