Calculation method of the reservoir operating rules using robust optimization

摘要

The present invention relates to a method for estimating water reservoir operation rules using robust optimization, wherein (a) the discretization module retrieves inflows from the inflow data DB where past inflow observation data are stored and discretizes the inflows, Fetching and discretizing the low volume; (b) a robust optimization performing module determining a monthly discharge amount (R _t ) for optimizing a robust objective function using the discretized low water amount and the discretized inflow amount; (c) the robust optimization performing module repeatedly calculates the robust objective function until the monthly discharge amount R _t of the step (b) is converged to an optimal solution, and (d) the reservoir operating rule preparation module is discretized. By setting the reservoir discharge rule, the monthly discharge (R _t ) calculated and calculated in step (c) as the number of possible cases according to the reservoir amount and the discretized inflow rate, the reservoir operation rule is greatly changed even when the reservoir operation rule is different from the present. By operating stably without fail, there is an effect of improving water supply reliability even in an environment where water is scarce.
