Этот сложный и непрерывный процесс обеспечивается управлением режимами энергосистемы. Для оптимального управления режимами необходимо анализировать характеристику потребления электроэнергии и прогнозировать график нагрузки. Прогнозирование потребления позволяет оптимизировать распределение выработки и обеспечивать надежность энергосистемы. Хотя существует множество методологий прогнозирования, не существует методологии, подходящей для всех энергосистем.</p><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. Прогнозирование суточного графика нагрузки для рабочих дней с учетом влияния метеорологических факторов центральной энергосистемы Монголии.</p></sec><sec><title>МЕТОДЫ</title><p>МЕТОДЫ. В работе использован метод, основанный на статистическом анализе. В качестве исходных данных использованы суточные графики нагрузки и данные о температуре и влажности наружного воздуха центральной энергосистемы, занимающейся большую часть энергопотребления и выработки в Монголии, за 2021 год. Работа проведена с помощью MS Excel.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. По методу статистического анализа были построены суточные графики нагрузки с погрешностью 2,68%. После учета метеофакторов погрешность уменьшилась до 2,26%.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. Использованный метод позволяет выполнять прогнозирование суточных графиков для рабочих дней. Многодневные периоды нерабочих дней, крупные аварии и плановые ремонты, ограничивающие потребление электроэнергии отрицательно влияют на точность прогнозирования.</p></sec></abstract><trans-abstract xml:lang="en"><p>A feature of the power system is that all the processes of production, transmission and distribution occur simultaneously. This difficult and continuous process requires the management by the regime of the power system. For precise regime managements, it is necessary to study the characteristic of electricity consumption. Forecasting demand allows to optimize the distribution of generation and ensure the safety of the power system. Therefore, forecasting is given a lot of attention in the energy section. Although there are many forecasting methodologies, but there is no exact methodology that is suitable for all power systems.</p><sec><title>PURPOSE</title><p>PURPOSE. To forecast the daily load schedule for working days, considering the influence of meteorological factors on the central energy system of Mongolia.</p></sec><sec><title>METHODS</title><p>METHODS. This study is carried out by the method of statistical analysis on MS Excel. As initial inputs historical data on load, temperature and outdoor air humidity of the central energy system were used, which has the most of the energy demand and sources of Mongolia by 2021.</p></sec><sec><title>RESULTS</title><p>RESULTS. According to the method of statistical analysis, daily load curves were constructed with an absolute percentage error of 2.68%. After adding into account of meteorological factors, the absolute percentage error decreased to 2.26%.</p></sec><sec><title>CONCLUSIONS</title><p>CONCLUSIONS. This method corresponds to forecasting daily schedules for working days. By restricting the electricity consumption during long continues non-work days, days with a major accident and planned maintenance will affect negatively to the planned tendency.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>прогнозирование</kwd><kwd>суточный график нагрузки</kwd><kwd>метеофакторы</kwd><kwd>энергосистема Монголии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>forecasting</kwd><kwd>daily load schedule</kwd><kwd>meteofactor</kwd><kwd>energysystem of Mongolia</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">Alfares H.K., Nazeeruddin M.
