摘　　要：优化传统微电网的容量配置对其经济性的提升效果有限。为进一步提升经济性,文中在传统微电网的基础上耦合垃圾填埋气发电(landfill gas power generation,LGPG)和电转气(power to gas,P2G),提出一种基于LGPG-P2G的微电网模型。首先,综合考虑碳交易和资金的时间价值对容量优化配置的影响,引入全生命周期理论和经济学中的净现值分析法;然后,以全生命周期的收益最大为目标,利用变异粒子群算法求解4种场景下的微电网容量最优配置,并使用Cplex求解传统微电网模型和所提微电网模型容量最优配置下的最优调度方案。结果表明在碳交易背景下基于LGPG-P2G的微电网模型具有更好的经济性。The optimization of capacity allocation of traditional microgrid has limited effect on improving economic efficiency.To solve this problem,a microgrid model based on the coupling of landfill gas power generation(LGPG)and power to gas(P2G)is propoed to improve economic efficiency.Considering the influence of carbon trading and the time value of capital on the optimal allocation of capacity,the full life cycle theory and net present value analysis method in economics are introduced.Then the mutation particle swarm optimization algorithm is used to obtain the optimal allocation of capacity in four scenarios for maximizing the benefit of the whole life cycle.The optimal operation scheme is obtained by Cplex under the optimal allocation of capacity of the traditional microgrid model and the proposed microgrid model.The simulation results show that the economic efficiency of proposed microgrid model based on LGPG-P2G is higher than that of tranditionl microgrid model under the background of carbon trading.
