考虑发电机组输出功率速度限制的最优机组组合

本文对发电机组输出功率速度限制条件下的电优机组组合问题进行了研究，提出了基于拉格朗日松弛原理的协调求解方法，构造在了构弛功率平衡约束的情况下的分离单机子问题的简单的网络模型，从而利用最短路径算法求出可行的组合方案。在此基础，利用动态优化调度的新算法－积留量法进行调整，从而达到机组组合与运行的良好协调，算例的试算，获得了较满意的效果。

Optimal Unit Commitment Considering Units Ramp-Rate Limits

Considering the ramp-rate limit of unit ,the optimal unit commitment is studied in detail in theis paper. Om thebasis of Lagrangian relaxation method,a coordination solution methodis proposed.Under the balance of relaxedpower the constraints are formulated and a feasible unit commitment is solved by the shortest path method.On thebasis of this,a new method of dynamlcoptirnal dispatch-accumulations variable method was used in order tofind global optimal solution. Therefore,a good coordination is achieved between unit commitment and operation. The effectiveness of the method is proved in the results of test.
