基于共享氢容量备用的多微网双层优化方法OA北大核心CSTPCD

Hydrogen storage offers advantages such as cross-seasonal and cross-regional storage;however,the short-term idle capacity caused by long-term hydrogen storage and significant fluctuations in the source and load of microgrids dominated by new energy sources urgently need to be addressed.This study develops a dual-layer operation optimization method for multiple microgrids,using shared hydrogen storage as capacity backup to utilize the short-term idle capacity of hydrogen storage to provide a backup for the microgrid,ensuring reliable power supply.First,a multi-microgrid reserve capacity setting method is proposed,based on an approximate normal distribution of system net load prediction error.Then,a hydrogen storage aggregator is introduced to construct a dual-layer optimization model for multiple microgrids based on shared hydrogen storage capacity,solved using an improved multi-objective sparrow search algorithm.Finally,through the verification of three microgrids in a specific region in northwest China,it was found that compared to independent solutions,the total operating cost of the cooperative alliance under the sharing model was reduced by 6.3%,carbon emissions were cut by 29%,and comprehensive energy efficiency improved by 4.8%.
