Optimizing Long-term Power Operation of Cascade Reservoir Based on Improved Kidney Algorithm

Cascade reservoir operation optimization plays a vital role in improving water allocation and promoting hydropower system management.The Improved Kidney Algorithm(IKA)provides an effective approach to the cascade reservoir operation model.The Kidney Algorithm(KA)is a novel nature-inspired optimization algorithm as well as widely applied and approved owing to its fewer parameters,superior search efficiency and robustness.In this paper,the optimization mechanism of KA is presented.To overcome the drawbacks of low diversity in population and inferior convergence,scaling factor-based movement strategy and adaptive strategy are introduced to configure the IKA.The feasibility and effectiveness of IKA is tested by solving cascade reservoir operation model.The results point out that:the IKA could significantly increase the hydropower generation(320 million kWh)of the cascade reservoir by 4.03%and largely decrease the spilled water volume by 17.54%in comparison to the KA.Mmeanwhile,the integrated strategies could effectively conquer the prematurity of the standard KA algorithm as well as lift the population diversity and algorithm convergence.
