Управление избытком и дефицитом выработки электрической энергии, способствующее стабилизации энергетической системы и повышению ее надежности, является актуальной задачей. Одним из решений является разработка и внедрение тепловых накопителей энергии в системы распределенной энергетики. Важной задачей при их разработке является создание эффективной системы теплоизоляции. ЦЕЛЬ. Разработка алгоритма для эффективного проектирования системы теплоизоляции тепловых накопителей энергии с высокотемпературным рабочим телом. МЕТОДЫ. Исследования проводятся с использованием теоретических методов, включая теплотехнический расчет слоев теплоизоляции и анализ теплопроводности. Использованы методы математического моделирования для определения толщины системы теплоизоляции теплового накопителя энергии. РЕЗУЛЬТАТЫ. Разработана конструкция теплового накопителя энергии. На основе разработанного алгоритма определено, что толщина системы теплоизоляции должна составлять 151 мм (толщина первого теплоизоляционного контура – 135 мм, толщина второго теплоизоляционного слоя из минеральной ваты – 16 мм), обеспечивая минимальные теплопотери при температуре теплоаккумулятора равной 2000 °C. Выявлено, что в слоях, ближайших к графиту, преобладает лучистый тепловой поток, составляющий около 70% от общего потока. ЗАКЛЮЧЕНИЕ. Исследование подтвердило эффективность предложенной многослойной системы теплоизоляции для теплового накопителя энергии. Разработанный алгоритм позволяет проводить расчёт систем теплоизоляции теплового накопителя энергии, который учитывает различные параметры и условия эксплуатации.</p></abstract><trans-abstract xml:lang="en"><p>RELEVANCE. Managing the surplus and deficit of electric power generation, which contributes to the stabilization of the energy system and enhances its reliability, is a pressing issue. One of the solutions is the development and implementation of thermal energy storage systems within distributed energy systems. An important task in their development is creating an effective insulation system. THE PURPOSE. To develop an algorithm for the effective design of insulation systems for thermal energy storages with high-temperature working bodies. METHODS. The research is carried out using theoretical methods, including thermal engineering calculation of thermal insulation layers and thermal conductivity analysis. Mathematical modeling methods were used to determine the thickness of the thermal insulation system of a thermal energy storage device. RESULTS. The design of a thermal energy storage device has been developed. Based on the developed algorithm, it was determined that the thickness of the thermal insulation system should be 151 mm (the thickness of the first thermal insulation circuit is 135 mm, the thickness of the second thermal insulation layer made of mineral wool is 16 mm), ensuring minimal heat loss at a temperature of the heat accumulator equal to 2000 °C. It was revealed that the radiant heat flux prevails in the layers closest to graphite, accounting for about 70% of the total flux. CONCLUSION. The study confirmed the effectiveness of the proposed multi-layer insulation system for thermal energy storage. The developed algorithm allows for the calculation of insulation systems of thermal energy storage, taking into account various parameters and operating conditions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тепловой накопитель энергии</kwd><kwd>система теплоизоляции</kwd><kwd>система распределенной энергетики</kwd><kwd>теплоаккумулятор</kwd><kwd>аккумулятор энергии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thermal energy storage</kwd><kwd>Insulation system</kwd><kwd>distributed energy system</kwd><kwd>heat accumulator</kwd><kwd>energy storage</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена за счет гранта Российского научного фонда № 24- 29-20061.</funding-statement><funding-statement xml:lang="en">the study was carried out with the financial support of the grant of the Russian Science Foundation No. 24-29-20061.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pimm, A.J., Palczewski, J., Barbour, E.R. et. al.
