Smart electrical networks and systems laboratory based on IoT platform

Connecting distributed energy resources (RES) changes the existing conception of the traditional distribution network as a passive network with a one-way flow of energy from the transmission network to end customers. The existing control mechanisms in the traditional distribution network are completely determined by the one-way flow of energy and subordinated to only one task: to reduce the voltage drop from the transmission network to the final customer in the low-voltage network. With the appearance of distributed sources, the distribution network becomes two-way, and in case of turning the energy direction (from the distributed source to the superior network), the problem of voltage drop in the opposite direction appears, i.e. the problem of voltage increase along the network. Accordingly, it is necessary to establish a laboratory model of an advanced distribution system that includes primary elements, but also advanced systems for monitoring, protection and management, and in order to train students for challenges in the power industry.
