大规模水电站群短期优化调度方法Ⅱ：高水头多振动区问题
Short-term optimal operation methods of large-scale hydropower plants II. Solution method for high-head generating units with multi-vibration zone
摘要
Abstract
The optimal operation of generating units with muhi-vibration zone is an important problem occurred to huge cascade hydropower plants. Generally, the vibration zone varies dynamically following the frequently changing working head due to the rapid response to complicated load demand, which will directly effects the safety of plants and power grids. A practical method is suggested to solve the optimal short term hydro scheduling of this kind of plants. The proposed method is based on the combined operation of generating units and dynamic programming and assembled mathematical technique are use to generate the optimal operation curves of virtual units with multi-vibration zones respectively. Furthermore, a strategy to avoid the occurrence of multi-vibration is incorporated into the progressive optimization algorithm to solve the model. The proposed method is applied to the Hongshuihe River cascade hydropower plants. The result shows that the method is feasible and practical.关键词
