Influence of Distributed Generation on Sectionalizing Switches Placement in MV Distribution Networks
Published by Wojciech BĄCHOREK1, Mariusz BENESZ1, AGH University of Science and Technology (1) Abstract. This paper presents the influence of distributed generation DG and reclosers placement on the reliability of distribution network. The brute force method and evolutionary algorithm were used to solve the optimization task. The placement of the switches was determined independently usingContinue reading “Influence of Distributed Generation on Sectionalizing Switches Placement in MV Distribution Networks”
What are Overcurrent Protection Devices?
Published by Alex Roderick, EE Power – Technical Articles: What are Overcurrent Protection Devices?, February 10, 2021. Learn about the basics of overcurrent, how it occurs, and ways to protect against and prevent it in power circuits. To have a properly operating circuit, current flow should be confined to a safe level. This safe level ofContinue reading “What are Overcurrent Protection Devices?”
