Optimum coordination of overcurrent relays in distribution systems using big-m and revised simplex methods
TLDR
This paper implements Big M and Revised Simplex method for optimum time coordination of overcurrent relays in a distribution network and identifies the optimized time multiplier setting (TMS) of the relay.Abstract:
Suitable protection system is a must to protect people and primary electric power equipment from disaster or damage Most frequent faults that occur in the distribution system are overcurrent faults Overcurrent (OC) relays are used significantly in protecting power distribution system from frequently caused faults like short circuits, ground faults, etc Optimization algorithms maybe used to minimize the time of operation of relays This paper implements Big M and Revised Simplex method for optimum time coordination of overcurrent relays in a distribution network and identifies the optimized time multiplier setting (TMS) of the relay This helps in quick coordination of overcurrent relays and also fast fault clearanceread more

Towards Constant Calculation in Disjunctive Inequalities Using Wound Treatment Optimization
TL;DR: This work proposes a new population-based metaheuristic optimization method, namely wound treatment optimization (WTO) for calculating the M-constant in a typical domain known as the fixed-charge transportation problem, inspired on the social wound treatment present in ants after raids.
