Research on Current Protection of Microgrid Based on Simulated Annealing Particle Swarm Algorithm

Microgrid technology has been widely used due to its high flexibility and reliability. In the operation process, it is prone to the situation that the system stability decreases due to untimely fault removal, and the microgrid current needs to be adjusted in time. A current protection scheme based on a simulated annealing particle swarm algorithm is proposed, which improves the particle swarm shrinkage factor and combines with the simulated annealing algorithm to shorten the current rectification time in the microgrid system by reasonably configuring the load in the simulated system, and the rationality of the method is verified by simulation. In this way, the premature problem of the particle swarm algorithm is solved well.
