New Overcurrent Relay Coordination Method Through Time Intervals to Enhance Microgrid Protection
IEEE Access, 2021 This paper presents a method to protect microgrids (MGs) through coordination of directional overcurrent relays (DOCRs). The new formulation is subjected to restrictions of pre-established time intervals to guarantee the primary and backup functions of ...

Coordination of Overcurrent Relay In Distribution System
ELEKTRIKA- Journal of Electrical Engineering, 2022 The overcurrent phenomena are a dangerous condition that can be occurred in the electrical system and equipment. The condition of the overcurrent will cause the short-circuited current flows through the system and affect the other distribution line. The purpose of this study is to investigate the coordination of the overcurrent relay in different types

Optimal coordination of overcurrent relays for microgrid operation using JAYA algorithm
e-Prime: Advances in Electrical Engineering, Electronics and EnergyIn modern microgrids, relay coordination is a very tedious task because of the variation in magnitude and direction of fault current. The change in fault current is diverse for inverter interfaced DGs (IIDGs) and synchronous-based DGs (SBDGs) The ...

Overcurrent and Earthfault Relay Coordination for Microgrid with Numerical Relay Features
International Journal of Innovative Technology and Exploring Engineering, 2020 This Paper deals with the Relay Coordination for microgrids by considering the symmetrical and unsymmetrical faults. A microgrid is an active distribution system in which the renewable energy sources and loads connected to feeders operate parallel or autonomously from the main power grid. In a microgrid, Overcurrent relays can be used as the protection

FEBS Letters, EarlyView.Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...
