Determination of Power Losses in the Sections of A Single-Loop Distribution Network with Connected Renewable Decentralized Energy Sources

The paper considers the determination of the power losses in hybrid medium voltage electric power distribution networks and more specifically in branches with connected renewable decentralized energy sources. After connecting the decentralized energy sources, sections with more than one power supply appear in the branches, which becomes a challenge for the operating personnel. This leads to a change in the structure of the network, its mode parameters, and also requires introduction of adjustments to the relay protection. The proposed software will be of use for engineers, operating with hybrid electrical networks and for students in their preparation for designing, reconstructing and working with similar networks, whose number is increasingly going up. It will also facilitate the choice of an optimal configuration for power supplying consumers in post-emergency situations.
