摘要
在满足黄委对西霞院水库下达的调令要求的前提下,小浪底-西霞院水库在制定发电计划时如何准确获得最佳调度策略?为此,构建了考虑西霞院黄委调令的水库群优化调度模型,并针对模型特点,提出了POA-GA嵌套搜索的求解方法。通过POA算法外层搜索符合调令需求下的下泄流量序列,寻求不同小浪底-西霞院出库流量的组合状态;另一方面,结合GA算法对小浪底-西霞院进行不同状态组合下的最优策略的搜索。通过实例分析结果表明,所构建模型能够确保小浪底-西霞院的调度策略满足黄委调令需求,提出的POA-GA嵌套循环搜索算法可在可行域内寻得最优解。该方法能够有效地指导小浪底-西霞院的调度工作,为决策者提供理论支撑。
Due to the requirements of the Yellow River Commission for the operation of Xiaolangdi-Xixiayuan reservoirs,the best operation scheme of the reservoirs cannot be derived accurately in formulating the power generation plan.For this reason,a reservoir group optimal operation model is constructed considering the operation order of Xixiayuan Reservoir,and a POA-GA nested search algorithm is proposed according to the characteristics of the model.The POA algorithm is used to search the demand flow sequence under the order demand,and seek the combination state of different outflow flows of Xiaolangdi-Xixiayuan Reservoirs.On the other hand,the optimal scheme of Xiaolangdi-Xixiayuan Reservoirs under different state combinations is searched by GA algorithm.The results show that the model constructed in this paper can ensure that the operation scheme of the reservoirs meet the needs of the Yellow River Committee dispatching order,and the POA-GA nested search algorithm can obtain the optimal solution in the feasible domain.The method can effectively guide the operation of Xiaolangdi-Xixiayuan Reservoirs and provide theoretical support for operators.
