具有预报信息的水电站群兴利优化调度模型

The Optimal Operation Model with Information Forecasting Function for a Hydroelectric Station Group

以黄河上游梯级水电站群为例，考虑水电站水库已备有的短期或中长期预报方案，建立其优化调度模型。以该模型所确定的调度方案为依据，对黄河上游５座水电站的各种可能来水进行调度，从而对这些水电站的期望电能及其抽样误差作出分析。结果表明，预报信息对于合理地预估总电能具有一定意义。

Based on cascade hydropower stations on the upper reaches of the Yellow River,considering that these hydropower stations have short term or mid and long term forecast scheme,the author sets up the optimal operation model.The operation scheme defined by the model has been applied to five hydropower stations on the upper reaches of the Yellow River according to various possible inflows for the analysis of expected energy output and sampling error.The results show that information forecast is useful for the estimation of electric energy output.
