Paper presents the software package that implements the ability to study hydroelectric power systems with complex hydraulic connections, planning long-term regime of hydro power plant with the requirements of water users on the example of the Votkinsk hydroelectric plants, and training for the calculation of the water-energy regime of hydroelectric power. The complex is developed in the high-level Python programming language based on the current requirements specified in the rules for the use of water resources of the Votkinsk reservoir. The calculation in the software package is performed by the direct method. Given that the software package is suitable for both research and training. To improve the quality of the calculation, we consider method of swarm optimization. The complex is planned to be used in the course of laboratory work on the planning of the HPP operation mode.
