Reservoir Operation Analysis Aimed to Optimize the Capacity Factor of Hydroelectric Power Generation

A reservoir operation was reviewed to optimize the total annual hydroelectric power generation. Analysis were conducted in a week period of time using daily data of reservoir level, turbine release, power generated, rainfall and evaporation. The length of data varies from 4-20 years (1991-2010). A trend test for historical daily power generation was performed using Nonparametric Mann-Kendall’s test to verify the improvement. The test results indicated that there is no trend in the generation of electricity. Optimal turbine release was found through genetic algorithm optimization model. The model results showed that the four-year average hydroelectric power generation capacity factor was improved from 31.48% to 33.62%, with better reservoir level and less variation in turbine release rates.
