Ensuring energy security of the Western energy district of the Republic of Sakha (Yakutia) through the implementation of an automatic emergency management system

RELEVANCE of the study is determined by the need to evaluate and analyze the effectiveness of implementing an automatic emergency response system to ensure energy security in the Western power district of Yakutia, which was isolated from the unified energy system of Siberia and the East until January 2019. The isolated regions of Yakutia had surplus power generated by hydroelectric power plants, thermal power plants, and diesel generators, which remained locked within them. After the unification of the power districts and the connection of Yakutia with the unified energy systems of Siberia and the East, problems arose in the area of energy security and the further development of energy systems.

THE PURPOSE. To analyze and evaluate the effectiveness of using automatic emergency response systems to ensure energy security in the Western power district of Yakutia.

METHODS. To achieve the goal and objectives, methods were used to calculate the static and dynamic stability of the power system, mathematical modeling of generating equipment, calculation and assessment of the maximum permissible energy flows in controlled sections, etc.

RESULTS. The external connections of Yakutia's electric power system with other Russian energy systems were described. The results of static and dynamic stability calculations and mathematical modeling were analyzed. An analysis of the results of calculations of the electrical modes of Yakutia's Western energy district was presented. Conclusions were drawn regarding power distribution from the Western energy district to the integrated energy systems of Siberia and the East. Technical solutions for local emergency control devices were selected. Recommendations for the use of automatic load shedding devices during power overloads were formulated.

CONCLUSION. The work identified the operational challenges of Yakutia's Western energy district. The potential for a multiplier effect from the implementation of emergency control devices was identified, which will stabilize the increase in power flows to energy-deficient regions, taking into account the Western energy district's resources of approximately 100 MW.
