Load Shedding Strategies Using Optimal Load Flow With Relaxation of Restrictions

Load-shedding Strategies for Preventing Cascading Failures in Power Grid

“…Besides these newly proposed strategies, load shedding has been a classical and a quite reliable mitigation strategy. There have been several discussions on optimal load shedding in literature recently and in the past [10], [12], [17], [18], [19], [20], [21], [22]. [17] proposes a load shedding method in steps with an equal frequency spacing between steps with an aim to avoid over shedding.…”

“…The authors of [20] propose an optimization problem for load reduction with relaxed constraints. They are of the view that if we allow the voltage to go below its minimum limit and the power flow to go beyond the capacity of the transmission lines for a very short duration, shedding of few loads would be sufficient to mitigate the problem and some of the load cuts can be prevented.…”

A robust undervoltage load shedding scheme against voltage instability

“…An efficient computational methodology was described in [9] using the sequential Monte Carlo simulation approach for comparing alternative strategies and artificial neural networks to determine directly the parameters of * Correspondence: imankaffashan@gmail.com protection strategy. In [10], the developed methodology minimizes the load cuts through the relaxation of the minimum limits of voltage and maximum limits of active power flows through the transformers. In [11,12] a combinational load shedding algorithm was proposed to enhance the voltage and frequency stabilities.…”

A new integer-value modeling of optimal load shedding to prevent voltage instability

“…Moreover, a number of different analytical based methods such as linear programming [14], interior point technique [15] and intelligent based methods such as particle swarm optimization (PSO) [6,7], artificial neural network [16,17], genetic algorithm (GA) [18][19][20], ant colony optimization (ACO) [21] and differential evolution [22,23] have been reported in recent years, aiming to minimize the load shedding amount.…”
