This paper provides a formulation of optimal control task, describes a simplified model for simulation of four different energy sources, consider a solution for optimization task in the numerical example and evaluates the impact of key parameters for selection of optimal regime. For determination of optimal solution, the following methods of mathematical programming are applied: dynamic programming – for efficient use of hydroelectric resources, linear programming – for optimization of other power plants and import. Utilization of mentioned methods guarantees the acquisition of global optimum.
