Changes in the operating modes of wind power plants (WPPs) should be compensated for by the ability of the control range of conventional power plants to load or unload active power. Therefore, when increasing the installed capacity of WPPs in power systems, improving the manoeuvrability characteristics of thermal power plants, including the expansion of the regulation range, is the main condition for reliable operation of the power system. The results of research on calculation of dynamic non-uniformity coefficient for different power systems with wind power plants are presented. Comparison of the results made it possible to establish that changes in WPP power with an amplitude of up to 40% of the installed or baseline WPP power and a fluctuation period of 15 minutes to 3 hours constitute the main time duration (about 90%). Using the Australian power system as an example, it is shown that the distribution of WPPs across the power system has a positive effect on load schedule levelling.</p></abstract><trans-abstract xml:lang="ru"><p>В условиях интеграции ветровых электростанций в электроэнергетические системы важным условием является обеспечение надежного энергоснабжения потребителей. Изменение режимов работы ветровых электростанций (ВЭС) должно компенсироваться возможностями регулировочного диапазона традиционных электростанций на загрузку или разгрузку по активной мощности. Поэтому при увеличении установленной мощности ВЭС в энергосистемах улучшение характеристик маневренности тепловых электростанций, в том числе расширение регулировочного диапазона, является основным условием надежной работы энергосистемы. Представлены результаты исследований по расчету динамического коэффициента неравномерности для различных энергосистем с ветровыми электростанциями. Сопоставление результатов позволило установить, что изменение мощности ВЭС амплитудой до 40 % от установленной или базисной мощности ВЭС c периодом колебаний от 15 мин до 3 ч составляет основную продолжительность времени (около 90 %). На примере энергосистемы Австралии показано, что распределение ВЭС по энергосистеме оказывает положительный эффект на выравнивание графика нагрузки.</p></trans-abstract><kwd-group xml:lang="en"><kwd>energy</kwd><kwd>electric power systems</kwd><kwd>flexibility</kwd><kwd>renewable energy sources</kwd><kwd>dynamic coefficient of unevenness</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>энергетика</kwd><kwd>электроэнергетические системы</kwd><kwd>маневренность</kwd><kwd>возобновляемые источники энергии</kwd><kwd>динамический коэффициент неравномерности</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Feng Sh, Wang W, Wang Z, Song Z, Yang Q, Wang B.
