JI UES has implemented a digital system for monitoring stability stocks on two system-forming controlled sections

2021: Using Digital Sustainability Inventory Monitoring System

On July 20, 2021, the system operator announced the beginning of the calculation of the maximum permissible active power overflows (TIR) using a digital stability inventory monitoring system (IMS) in two controlled sections of the central part of the UES of Russia.

"1 section" and "Kalinin - Konakovo" - controlled sections (a set of power transmission lines), through which electric power is transferred from the energy-surplus Joint Energy System of the North-West and the energy system of the Tver Region, where the Kalinin NPP is located, to the central part of the UES of Russia. Due to the high importance of these controlled sections for the control of the electric power regime of the UES of Russia, operational dispatch control is carried out from the Main Dispatch Center of the UES in Moscow.

Control of the mode of the power system using the results of the calculation of SMZU allows, without reducing reliability, to ensure the maximum use of the actual capacity of the electric network in the controlled sections "1 section" and "Kalinin - Konakovo" with optimal load distribution between the electric stations.

"1 section" and "Kalinin - Konakovo" are the first controlled sections for which the TIR calculation is carried out using SMZU in the Main Dispatch Center of the UES of Russia.

SMZU is a software and technical complex developed by JSC STC UES together with JSC SO UES, which brings the TIR calculation process in the electric network to a fundamentally different level. The system is designed to calculate the value of the maximum allowable overflow in real time, which allows taking into account current changes in the circuit-mode situation in the power system and thereby provides additional capabilities for using the capacity of the electric network and choosing the optimal algorithm for controlling the modes of the power system without reducing its level of reliability.

The introduction of SMZU is an important step towards the digitalization of energy along with such projects as the commissioning of centralized third-generation emergency automation systems in integrated power systems, remote control systems for equipment of energy facilities and RZA devices and other digital technologies. The use of such solutions in the electric power industry allows you to achieve a significant positive effect by building on their basis more efficient models of technological and business process management.
