Search for the dispatch schedule optimal configuration for managing releases of the complex “Lake Baikal - Irkutsk Reservoir”

Abstract

The article considers methods for constructing optimal (in the Pareto sense) coordinates of the dispatch schedules for managing releases for the water management complex “Lake Baikal - Irkutsk Reservoir”. Statistical reliability criteria such as the number and depth of violations are used as optimization criteria. The construction of the optimal dispatch schedule is carried out based on water resource calculations for long-term hydrological inflow series from 1903 to 2016 (the number of the periods per year is 24) and modern hierarchically ordered requirements of water users. Since the water users’ requirements, as a rule, conflict with each other, a multi-criteria analysis of various optimal dispatch schedules were used to find the optimal Trade-off solution. To search for the optimal configuration of the dispatcher, the author’s methods of local optimization were developed, which allow solving a complex non-linear programming task in a reasonable time. Software for water resource calculation and optimization was developed with the VBA language in the Excel environment.
