Considering the electricity-carbon-hydrogen coupling,the multi-integrated energy microgrid connected to the distributed optimal operation of the distribution network
In order to fully explore the dispatching potential of integrated energy microgrid(IEM)and promote the transformation of new power system,a collaborative distributed optimal operation method for multi-integrated energy microgrid access to distribution network was proposed.Firstly,an IEM model was constructed,and the multi-type applications of hydrogen energy,including combined heat and power(CHP),hydrogen fuel cell(FC)and hydrogen storage,were constructed to form a comprehensive energy microgrid with electricity-carbon-hydrogen coupling.Reduce carbon emissions and exploit the full potential of carbon capture units and hydrogen dispatch.Then,after the construction of the single microgrid model,aiming at the problem of multi-integrated energy microgrid access to the distribution network,the integrated energy microgrid and the distribution network are regarded as different sub-regions,and the distributed optimal operation model of multi-integrated energy microgrid access distribution network is established.The alternative direction method of multipliers(ADMM)was used to solve the model.Finally,the simulation results based on the improved IEEE33-node distribution network show that the system scheduling cost is reduced by 10%and the carbon emission is reduced by about 65%after the multi-IEM access distribution network system considering the electricity-carbon-hydrogen coupling,and the difference between the results obtained by distributed optimization and the centralized one is only 0.8%,which verifies the effectiveness and superiority of the proposed method.
