Оптимізація місць секціонування електричної мережі з відновлювальними джерелами енергії

Abstract

The method of determining the rational distribution point of distributive electrical networks is developed, taking into account the impossibility of transporting power from distributed sources of generation, when there is damage in the electrical network or there are restrictions on the use of electrical equipment due to their technical condition, this applies in particular to switching devices. The method allows to determine the technical and economic effect of installing additional switching devices for network segmentation and use of RES in order to reduce electricity losses in the electric network. It is shown that in distributive power networks with distributed generation, classified according to the requirements of reliability, it is possible and appropriate to construct a system for controlling power flows to reduce electricity losses during its transportation. For this purpose it is expedient to involve managed renewable power sources. First and foremost, these are small HPP, as well as solar power stations with a group inverter and a power storage device.
