为了充分发掘综合能源微网(IEM)的调度潜力,促进新型电力系统转型,提出了多综合能源微网接入配电网的协同分布式优化运行方法.首先,构建IEM模型,包括掺氢热电联产机组(CHP)、氢燃料电池(FC)和储氢的氢能的多类型应用,形成电-碳-氢耦合的综合能源微网,减少碳排放和充分挖掘碳捕集装置和氢能的调度潜力.然后,在单微网模型构建之后,针对多综合能源微网接入配电网问题,将综合能源微网和配电网看作不同子区,建立多综合能源微网接入配点网的分布式优化运行模型.并采用自适应步长的交替方向乘子法(ADMM)求解模型.最后,基于改进型IEEE33节点配电网的仿真测算表明,考虑电-碳-氢耦合的多IEM接入配网系统后系统调度成本减少了10%,碳排放减少了约65%,且采用分布式优化所得结果与集中式差距仅为0.8%,验证了所提方法的有效性和优越性.
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.
