Innovations

According to the global trend, work continues in the field of modern innovative and digital technologies, the basis of which is the introduction of various elements of intelligent management of network facilities (measurement, monitoring, control and management systems), on the basis of which a new generation of electric networks, the so-called ‘Smart Grid’, can be created.

The construction of an intelligent energy system (Smart Grid) affects all participants in the electric power industry: generation, transmission, distribution, supply, consumption and system operation.

Smart Grid assumes the ability to control the behavior of all its participants in real time in order to ensure sustainable, cost-effective, safe power supply and improve the quality of services provided, their accessibility and implies obtaining technical and economic benefits from the integration of all participants in the energy network, which ensures a high level of reliability and safety.

Total costs of KEGOC JSC for technological development in 2023


15,09 KZT million

The main directions of Smart Grid in the Republic of Kazakhstan, extended to the sectors of generation, transmission and distribution, sales and consumption of electricity, are:

Monitoring

includes a set of technologies that ensure the collection and processing of information in real time to monitor the operating modes of the electric power system and the condition of its assets.

Power system management

includes a set of technologies that affect control facilities in real time in order to ensure the normal operation of the electric power system.

Accounting

includes a set of technologies aimed at measuring quantities in real time, used for appropriate settlements between entities.

Asset management

includes a set of technologies aimed at maximizing the efficient use of electrical installations throughout their life cycles and making management decisions regarding electrical installations.

Data management

includes a set of technologies aimed at integrating information systems, displaying information about current and forecast data in real time in general and by subject and territorial affiliation.

KEGOC JSC is actively implementing Smart Grid technologies to improve the reliability and efficiency of the UPS of the Republic of Kazakhstan. Currently, projects are under implementation to modernize the SCADA/EMS system and expand the WAMS monitoring system (stage 2), which will improve the efficiency of dispatching control and the observability of the modes of operation of the UPS of the Republic of Kazakhstan, as well as ensure monitoring of stability reserves and assessment of the state of the UPS of the Republic of Kazakhstan as a whole.

In 2023, the implementation of the Pilot Project ‘Introduction of electric power storage systems in the UPS of the Republic of Kazakhstan’ (Pilot project) was launched to study the impact of electric power storage systems on the regulation of the UPS during the integration of renewable energy sources. On December 4, 2023, an Agreement was signed between KEGOC JSC, China Power International Development Limited, China Power International Holding Limited and the Association of Renewable Energy of Kazakhstan for the implementation of this Pilot Project.

Following the results of the Pilot Project, with the support of the Association of Renewable Energy of Kazakhstan, recommendations will be developed on amendments to regulatory legal acts of the Republic of Kazakhstan and the development of regulatory and technical documentation on the use of electricity storage systems in the UPS of the Republic of Kazakhstan.

The implementation of the Pilot project will stimulate the development of electricity storage technologies in the Republic of Kazakhstan, which in turn will ensure an increase in the number of renewable energy sources in the country.

According to the Pilot project, it is planned to install an electric power storage system at a 500 kV substation ‘City step-down substation’ with a capacity of


6,77 MWh
