Optimization Scheduling of Island Microgrids Based on Improved Grey Wolf Algorithm
To improve the econmic efficiency of the operation of island microgrid,an optimization scheduling model for island microgrids was established to improve the economic efficiency of island microgrid operation,with the total operating cost of the island microgrid as the objective function and considering the benefits brought by seawater desalination.The grey wolf optimization(GWO)algorithm was improved using three strategies:Tent chaotic mapping,nonlinear adjustment of convergence factor,and Cauchy mutation.The improved grey wolf optimization(IGWO)algorithm was used to solve the optimization model of the island microgrid.The results show that the total operating cost of the island microgrid considering seawater desalination load during the scheduling cycle is 3 086.03 yuan(RMB),compared with the latter,the total operating cost of the island microgrid without considering seawater desalination load is reduced by 538.32 yuan(RMB),and the economic efficiency is improved by 14.85％,thus verifying the correctness and superiority of the proposed model.
