First, the technique without network voltage sensor with a direct power control based on a switching table, which is a classic approach, is discussed and its performance is analyzed under increasing and decreasing load.

The proposed method is verified using MATLAB/Simulink. Results. The simulation results under different input voltage conditions show that the proposed method not only has good tracking performance in active and reactive power, but also reduces the current total harmonic distortion to 1.9 %, which is good lower than the requirement for network operation. Вступ. Якість електроенергії має важливе значення під час збоїв, на рівні силових електронних пристроїв будуть мати місце серйозні проблеми експлуатації, що викликають небезпечні пошкодження. Мета. Новий підхід до прямого керування потужністю без датчика напруги мережі покращує якість та контроль перетворювачів миттєвої активної та реактивної потужності. Методологія. Спочатку обговорюється методика без датчика напруги мережі з прямим керуванням потужністю на основі таблиці перемикання, що є класичним підходом, та аналізується його продуктивність при збільшенні та зменшенні навантаження. Крім того, ефективність запропонованої методики також аналізується за тих же обставин, і їхня продуктивність порівнюється. Оригінальність. Новий метод складається з нелінійного мережевого контролера з модуляцією напруги і звичайного контролера, який гарантує дуже хороші результати в забрудненій мережі. Запропонований метод перевіряється за допомогою MATLAB/Simulink. Результати. Результати моделювання за різних умов вхідної напруги показують, що запропонований метод не тільки має хороші характеристики відстеження активної та реактивної потужності, але також знижує поточний THD до 1,9 %, що значно нижче, ніж вимоги для роботи мережі.
