The paper deals with an isolated electric power system (EPS) based on hydroelectric power plants. The analysis of the existing methods and approaches for investigation of modes of EPS which comprise hydroelectric power plants is presented. A mathematical model of a hydroelectric station cascade has been developed, which allows taking into account the hydraulic connection during calculation of electrical modes. A software tool for optimization the operating modes of hydroelectric power plants as part of the power system was developed. It uses redistribution the load between hydraulic units both inside the station and between hydroelectric complexes of cascade hydroelectric stations. The task of modeling power consumption and load graphs of EPS with specific properties, based on the application of artificial intelligence methods, is considered.

The possibilities of using shunting properties of HPP units, HAPS (Hydro-accumulating power system) for energy storage and redistribution, as well as Pump Station as a consumer of the regulator in night load dips to increase the reliability of the electric power system (EPS) in the conditions of the current increase in the share of non-nondestructive capacities in Russia and Uzbekistan and the implementation of programs for the development of renewable energy sources, primarily the construction of wind and solar power plants, were considered.

Basing on the principles of historicism and objective analysis the article examines the features and problems of implementing two state electrification plans: GOELRO plan adopted 100 years ago, under which the construction of local power plants in the Middle Volga region began, and the General Plan for the USSR Electrification, approved in 1932, which laid down the main solutions to radically redevelop the industry and agriculture of the region on the basis of using the sources of hydroelectric power, constructed on the Volga. In this regard, the historical and comparative method made it possible to highlight the main stages in creation and development of the power system of the Chuvash Republic, which since the mid 1950s has acted as a central a link in the country’s unified electric power system. The idea of creating energy hubs of the Volga Cascade, which in the years that followed provided the rise of industrial and agricultural production of the region, was based on the need for the priority development of the integrated power grid taking into account a strictly defined sequence of regional power plant construction, however, these aspects of implementing the electrification plans are not exampled in the domestic historical literature devoted to the reform of the energy industry. The article notes the pivotal role of scientific and technical cooperation between Leningrad and Cheboksary power engineers and instrument makers in solving the most complicated tasks in times of peace and during the war, it considers the contribution of Chuvash power engineers, who provided the construction and modernization of dozens of trunk transmission lines, which made it possible to fully implement the country’s electrification plan and to ensure energy security of the region.

This paper presents an optimization-based method for the long-term scheduling of hydrothermal power system with several multiple-user reservoirs. The proposed method maximizes the profit of various types of water utilization taking into account limited water resources and all accomplishable restrictions. Hydroelectric power plants and other water users are treated like a peer participant in the profit realization. The method has been implemented in a computer program and tested on real system. .

A mathematical model of frequency and power regulation in power systems with large wind power plants (WPPs), hydroelectric power plants (HPPs), and battery energy storage systems (BESSs) was developed. Using this model, we carried out a complex of studies over a wide range of changes in the power of HPPs, BESSs, and their proportions. Options are considered when HPP and BESS work separately. The conditions under which HPPs and BESSs provide a stable operation of the power system, working separately with satisfying the requirements to frequency deviation in the integrated power system of Ukraine and in the ENTSO-E energy system of the European Union are determined. A series of calculations for the joint use of HPPs and BESSs was carried out, and, as a result, recommendations were formulated on the conditions for joint operation of HPPs and BESSs.
