This report presents a hybrid model that calculates the heads and flow rates of a hydraulic network system and then uses a genetic algorithm to optimize the operational control of the hydraulic network. To calculate the steady flow and the extensive period the Matrix Method was used. The GA used binary numbers. The objective function minimizes the sum of the dissipated hydraulic power in the whole network of all calculated periods during the day. The hybrid model part that refers to the hydraulic calculation is working satisfactorily, because the values calculated by the model applied to the networks used as examples are similar to the ones obtained from the technical literature. The hybrid model part that refers to the GA is working satisfactorily, because the objective function values calculated by the model converged whenever the elitism was used. The proposed optimization in this work is to be used in hydraulic networks that present operational problems that need to be solved either by installing valves or having installed valves. Keywords: hydraulic networks operation, optimization. 1 Introduction Optimization is a search process for a problem solution that uses several techniques to find the most efficient solution. The operational control optimization of hydraulic networks is usually obtained using linear programming with several restrictions, because the equations that represent the flow rate are non-linear.
