This study maximizes the total electric sale profit of a hybrid power system with one thermal power plant (TPP), one wind power plant (WPP), one solar power plant (SPP), and one pumped storage hydro plant (PSP) scheduled in one day. There are no inflows to the PSP, and the PSP only uses the pumped water to produce electricity. Two study cases are simulated using artificial hummingbird algorithm (AHA), war strategy optimization algorithm (WSO), and average and subtract-based optimization algorithm (ASBO). As a result, ASBO reaches the highest profit for the two cases. In addition, ASBO is also run for two other cases neglecting the operation of the PSP. The results indicate that PSP can support the system to reach a greater profit by $1859.8 and $1,577.7, respectively. Thus, the PSP is very useful for the hybrid system in reaching the maximum total profit of the electricity sale.
