针对金沙江下游梯级水库的相继建成将会改变长江流域梯级水库综合调度格局问题,构建了金沙江下游梯级水库与三峡梯级水库联合发电调度模型,并采用逐次优化算法进行了求解。结果表明,采用联合优化调度后整个梯级发电效益明显,与原设计方案相比梯级平均发电量可增加6.29%;与各梯级单独优化运行相比,梯级发电量可增加1.48%。
The successive construction of cascade reservoirs in the lower reaches of the Jinsha River will change the overall dispatch pattern of the cascade reservoirs in the Yangtze River Basin. The joint dispatch model for the cascade reservoirs in the lower reaches of the Jinsha River and the Three Gorges cascade reservoirs has been constructed and solved by the successive optimization algorithm. The results show that the whole cascade power generation with joint optimization scheduling has obvious benefits. Compared with the original design scheme, the average cascade power generation can increase by 6.29%. Compared with individual cascade optimization, cascade power generation can increase by 1.48%.
