| Abstract: | В роботі на основі аналізу проблем забезпечення
якісного електропостачання в умовах інтенсивної розбудови відновлюваних джерел енергії (ВДЕ) та визначених
засобами кваліметрії характеристик електричних мереж,
які є істотними для забезпечення якісного електропостачання, запропоновано застосовувати макромоделювання
електричних мереж для оцінювання якості їх функціонування у вигляді інтегральної характеристики готовності
електричної мережі з ВДЕ. Це сприятиме розробленню
узагальнених рішень та стратегії розвитку мереж, особливо
коли йдеться про розбудову ВДЕ. Складові інтегрального
показника визначаються як імовірність відповідності фактичного режиму “ідеальному”. “Ідеальний” режим визначається, виходячи з принципу найменшої дії і відповідає
заступній схемі мережі, сформованій за r-схемою. Визначений таким чином базис дає змогу знизити суб’єктивність
і оцінки, і прийнятих на основі неї рішень. In the article it is proposed to use macro-modeling of electrical grids for assessing the quality of their operation in the form of an integrated readiness characteristic of electrical grids with RES. It has been done on the basis of the analysis of the problems of providing high-quality electrical supply under conditions of the intensive development of renewable energy sources (RES) and characteristics of electrical grids determined by means of qualimetry that are essential for providing high-quality electricity. This will contribute to the development of generalized solutions and grid development strategies, especially when it comes to RES development. The components of the integral index are determined as the probability of matching the actual mode to the “ideal” one. The “ideal” mode is determined by the principle of least action and corresponds to the circuit diagram of the grid formed by the r-scheme. The basis determined in this way reduces the subjectivity of both evaluations and decisions taken on their basis. |
