Optimal Capacity Allocation of Marine Microgrid Based on Particle Swarm Optimization Algorithm
At present,due to the increasing price of traditional energy under the influence of energy crisis,it is difficult for the traditional ship power mode to meet the new emission standards,forcing the ship power system to carry out energy transforma-tion.Therefore,this paper establishes an independent ship power grid system composed of battery,super capacitor,photovoltaic and diesel generator,and establishes the objective function and constraints.The economy,reliability and environmental protection are considered in order to allocate the capacity of ship power grid reasonably.In this paper,the concept of genetic algorithm is used to introduce the crossover process of genetic algorithm before particle swarm optimization updates particles,so as to produce better quality offspring individuals.Then this algorithm is applied to the capacity optimization of the target ship in different working condi-tions.Compared with particle swarm optimization algorithm and genetic optimization algorithm,the optimal capacity allocation scheme is obtained.
