Abstract

The invention relates to an estimation method of a dispatching zone and a device thereof, in particular to a dispatching zone estimation method for reservoir determinacy optimizing dispatching and a device thereof. The invention is an estimation method for optimally dispatching a track zone of reservoir determinacy optimizing dispatching. The invention provides the method for dispatching reservoirs according to an optimal dispatching zone the first time, and the key of the method is the estimation problem of the optimal dispatching zone. The invention takes the dispatching tack of the reservoir determinacy optimizing dispatching problem as a parameter with a probability distribution characteristic, takes a dispatching objective function value as a likelihood function, and adopts a bayesian method to estimate the zone distribution of the optimal dispatching track. The invention ensures the optimal dispatching zone range of the reservoir, analyses the dispatching efficiency of the adjacent zone of the optimal dispatching track, evaluates the key dispatching periods, and can provide more supported information for dispatching decisions.
