【摘要】：水库短期优化调度关系到水库中长期调度计划能否顺利在厂间实现,是水电站实际运行中的重要一环。为保证短期优化调度制定的计划满足电网稳定运行的要求,在一般短期优化模型的基础上加入电网稳定性约束,以发电量最大为目标建立梯级水电站短期优化调度模型,采用逐步优化算法(POA)进行求解,寻求梯级水库系统在满足电网稳定运行基础上的最优运行方式。以雅砻江流域"锦官电源组"3级水库群为例,进行了考虑电网约束的梯级水电站短期优化调度,并与传统优化调度模型的调度结果进行对比分析。分析结果表明,调度结果满足电网稳定性要求,更有利于电网安全、稳定运行。
[Abstract]:Short-term optimal operation of reservoirs is an important part of the practical operation of hydropower stations, which is related to whether the long-term operation plan of the reservoir can be smoothly realized between the plants. In order to ensure that the plan of short-term optimal dispatching can meet the requirements of stable operation of power network, the stability constraint is added to the general short-term optimization model, and the short-term optimal dispatching model of cascade hydropower stations is established aiming at the maximum power generation. In order to find the optimal operation mode of cascade reservoir system on the basis of satisfying the stable operation of power network, a step by step optimization algorithm (POA) is adopted to solve the problem. Taking the third level reservoir group of "Jinguan Power supply Group" in Yalong River Basin as an example, the short-term optimal dispatching of cascade hydropower stations considering power network constraints is carried out, and the results are compared with those of the traditional optimal dispatching model. The results show that the dispatching results meet the requirements of power grid stability and are more conducive to the safe and stable operation of the power grid.
