Optimal Reservoir Operation Policies Using Genetic Algorithm

Abstract

In reservoir operation, appropriate methodology for deriving reservoir operating rules should be selected and operating rules should then be formulated. In the present study Genetic Algorithm (GA) has been used to optimize the operation of existing multipurpose reservoir in India, and to derive reservoir operating rules for optimal reservoir operations. The fitness function used is minimizing the squared deviation of monthly irrigation demand along with the squared deviation in mass balance equation. The decision variables are monthly releases for irrigation from the reservoir and initial storages in reservoir at beginning of the month. The constraints considered for this optimization are reservoir capacity and the bounds for decision variables. Results show that, even during the low flow condition the GA model if applied to the Upper Wardha reservoir in Maharastra State, India, can satisfy downstream irrigation demand. Hence based on the present case study it can be concluded that GA model has the capability to perform efficiently, if applied in real world operation of the reservoir.

Optimal long term operation policies associated with the generated affectations – low regulation capacity reservoirs

“…Considering the average daily flows, as well as the characteristics of the reservoir presented in Table 2, the optimization of longterm operation policy was performed. [17][18][19] Runoff matrix for the reservoir analytical simulation was built in to fortnightly intervals. To distribute the annual average volume in to intervals throughout the year (considering the flood and dry seasons), six monthly groups were defined, which are conformed as showed in Table 3.…”

“…Considerando los gastos medios diarios, así como las características del embalse presentadas en la tabla 1, se efectuó la optimización de la operación a largo plazo (Chang y Chang, 2009;Mathur y Nikam, 2009;Kuo et al, 2003). La matriz de escurrimientos para la simulación analítica del vaso se construyó para intervalos quincenales.…”
