Исследование выполнено на основе метода машинного обучения, в частности ансамблевых моделей и статистических ранговых моделей для построения модели суточного графика электропотребления, а также генерации ветровых и солнечных электростанций. Расчеты выполнялись с использованием открытого программного обеспечения Pandapower, что позволило учесть реальные технические характеристики электросетевого оборудования, провести анализ нормальных режимов и оптимизацию режимных параметров. Результаты моделирования показали, что интеграция четырех гидроаккумулирующих электростанций суммарной мощностью 250 МВт позволяет значительно сгладить неравномерность суточного графика выработки тепловых станций. Коэффициент неравномерности, показывающий отношение минимальной суточной нагрузки к максимальной, возрос с 0,8 до 0,96. Анализ режимных параметров не выявил перегрузки системообразующих линий электропередачи или недопустимого отклонения напряжения в узлах. Показано, что суммарные потери мощности в Центральной энергосистеме Монголии при интеграции гидроаккумулирующих электростанций незначительно возросли и составили 5,54% (без учета они составляли 5,36%). Это подтверждает, что перераспределение значительных объемов мощности, связанное с ростом доли возобновляемых источников энергии в энергосистеме Монголии, требует тщательного анализа технического состояния оборудования и увеличения пропускной способности линий электропередачи. Таким образом, внедрение гидроаккумулирующих электростанций к 2030 г. сделает управление режимами работы центральной энергосистемы Монголии более гибким. Это позволит увеличить внутреннее производство электроэнергии, снизить активные потери в сети, уменьшить объем импорта электроэнергии из России, сократить риски перебоев в центральном регионе Монголии и эффективно решить проблему дефицита электроэнергии.</p></abstract><trans-abstract xml:lang="en"><p>The paper is aimed at assessing the impact of integrating pumped-storage power stations on the steady-state operation of the Mongolian central power system, as well as its operational reliability, in the context of growing power consumption and the increasing share of renewable energy sources. The study was conducted employing the machine learning method (specifically, ensemble models and statistical ranking models) to build a model of the daily load curve, as well as the power generation of wind and solar power plants. The computations were performed using the Pandapower software, which provided a means to take into account the actual technical characteristics of power grid equipment, analyze normal conditions, and optimize the operating conditions. The modeling results indicate that the integration of four pumped-storage power stations with a total capacity of 250 MW significantly smoothes out the irregularity of the daily output curve of thermal power plants. The irregularity factor indicating the minimum-to-maximum daily load ratio increased from 0.8 to 0.96. An analysis of operating conditions did not reveal overloading of backbone transmission lines or unacceptable node voltage deviation. The total power losses in the central energy system of Mongolia were shown to increase insignificantly with the integration of pumped-storage power stations amounting to 5.54% (5.36% without taking them into account). This fact confirms that the redistribution of significant amounts of power associated with the growing share of renewable energy sources in the Mongolian power system requires a thorough analysis of the technical status of equipment and an increase in transmission line capacity. Thus, the integration of pumped-storage power stations by 2030 will make the control of the Mongolian central power system more flexible. This will increase domestic power generation, reduce ohmic losses in the grid, decrease the volume of power imports from Russia, lower the risks of outages in the central region of Mongolia, and effectively solve the power shortage problem.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электроэнергетическая система</kwd><kwd>гидроаккумулирующая электростанция</kwd><kwd>возобновляемые источники энергии</kwd><kwd>баланс активной мощности</kwd><kwd>установившийся режим</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electric power system</kwd><kwd>pumped storage hydropower plant</kwd><kwd>renewable energy sources</kwd><kwd>active power balance</kwd><kwd>steady state</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bat-Erdene B., Voropai N.I., Batmunkh S., Zhargalsaikhan B., Lyankhtsetseg S., Bat-Undral B.
