Summary: This study proposes a novel parallel approximate evaluation-based model (PAEM) to enhance the search ability and shorten the calculation time in reservoir operation optimization, while accurately controlling approximation errors. By combining PAEM with LSTM, the PAEM-LSTM model is developed for fast formulation of operating rules. Results show that PAEM provides significantly better Pareto-optimal solutions at a faster speed compared to other algorithms, while maintaining extremely low approximation errors. PAEM recommends a small population size and large mutation size, and its efficiency increases with the scale of the reservoir group. The PAEM-LSTM model can increase hydropower generation and reduce ecological water shortage compared to conventional operating rules.

Summary: This study develops a modeling framework called COREGS, which optimizes the allocation of water resources and reduces power generation costs through the co-optimization of reservoir and electricity generation systems. The findings suggest that co-optimization leads to more efficient water allocation decisions and better meets the needs of the power system compared to separate optimization.

Summary: By coupling the non-dominated sorting genetic algorithm-II (NSGA-II) model and the General Lake Model-Aquatic EcoDynamics library (GLM-AED) model, reservoir operation strategies (ROSs) can effectively control algal blooms. In the case of Zipingpu Reservoir, the peak of outflow discharge can be reduced by 19%, total power generation can be increased by 8%, and the peak of chlorophyll a concentration can be decreased by 36% compared to the original reservoir operation. Balancing the objectives of algal bloom control, flood prevention, and power generation is crucial in reservoir operations.

Summary: In this study, a coordination model of power generation and ecological flow for cascade hydropower system was established using a multi-objective optimization method. Three MOGAs (NSGA-II, NSGA-III, and RVEA) were selected to solve the model, and the results show that NSGA-III has certain advantages over NSGA-II and RVEA in terms of performance metrics. Therefore, NSGA-III is recommended as the solution algorithm for the established coordination model.
