【摘要】 水库优化调度问题一直是国内外研究的热点问题之一,水库优化调度需要解决两大技术问题,一个是优化调度模型的建立,另一个是模型的求解方法。本文在水库优化调度研究中主要针对模型新的求解方法进行了研究。在总结国内外相关研究成果的基础上,分析目前水库优化调度研究中存在的问题及其未来的发展趋势,尝试在水库优化调度模型求解方法方面做进一步研究,将复合形混合演化(SCE-UA)优化算法应用于水库优化调度模型的求解中。通过对SCE-UA算法基本原理的深入研究,根据该算法的特点和优势及其对水库优化调度模型的要求,建立了基于SCE-UA算法的水库优化调度发电量最大模型,实现了用SCE-UA算法进行求解,与传统的动态规划方法计算结果进行比较,得到了比动态规划方法更优的结果,证明了该算法用于水库优化调度模型求解的可行性、有效性和准确性。对电力市场环境下的水库优化调度问题进行了研究,在常规水库优化调度发电量最大模型的基础上,考虑不同时期的电价差异,建立了基于SCE-UA算法的水库优化调度分时电价模型,采用SCE-UA算法,实现了对模型进行求解,实例应用取得了较好的结果,与发电量最大模型相比,在一定程度上增加了水电站水库的发电效益,为水库优化调度提供了一种有效适用的优化算法和求解思路。更多还原

【Abstract】 The research on reservoir optimal operation is one of the hottest issues domestically and internationally.Two technical problems in reservoir optimal operation are the establishment of optimal scheduling model and the method for solving the model. In the paper, the new method for solving the model of reservoir optimal operation has been mainly studied in this research.On the basis of the results of current national and international research, the existing problems and development trend of future research have been analyzed in the reservoir optimal operation at present. Further exploration and research are made for the method of solving the reservoir optimal operation model. The shuffled complex evolution optimization algorithm (SCE-UA) has been applied in solving the model of reservoir optimal operation.The basic principle of SCE-UA algorithm has been studied thoroughly.The reservoir optimal operation model of maximum power generation based on SCE-UA algorithm was established according to the features and advantages of the algorithm and the requirements of the reservoir optimal operation.Compared with the results of dynamic state programming method, the results of SCE-UA algorithm are much better. It proves that the SCE-UA algorithm is feasible, effective and accurate in solving the model of reservoir optimal operation. The problem of the reservoir optimal operation in the power market has also been studied. On the basis of the conventional reservoir optimal operation model of maximum power generation, the reservoir optimal operation model of time-varying electricity price based on SCE-UA algorithm is established considering the different prices in different periods. The SCE-UA algorithm is used to solve the model. The results are relatively good in the application example.Compared with the model of maximum power generation, the generation benefit of the reservoir increases to a certain extent. It provides an efficient and suitable algorithm and a new solution idea for reservoir optimal operation.更多还原
