A Group Search Algorithm for Optimal Scheduling of Cascade Hydropower Stations

Renmin Zhujiang
The coronavirus herd immunity optimizer (CHIO) algorithm was introduced to address the optimal scheduling problem of cascade hydropower plants, and an improved algorithm called LCHIO was proposed. The CHIO algorithm was enhanced by adopting two strategies: the Latin hypercube strategy for generating initial population solutions and dynamic social ...
