摘　　要：为全面评估微电网系统不同运营方式下的经济性,从全社会角度出发,综合分析余电上网和余电制氢2种运营方式下微电网系统的成本和效益。考虑到不同类型、不同容量的分布式电源对微网系统各方面性能的影响,首先对微电网中的分布式电源定容问题进行研究。在满足具体约束的前提下,以全生命周期综合收益最大为目标函数,建立微电网系统双层优化模型。该双层优化模型上层优化采用自适应粒子群算法求解系统最优配置,下层优化采用CPLEX求解器求解上层配置方案下的最优调度方案。在此基础上,运用所建全寿命周期经济性评估模型,对具体算例最优配置下各成本和收益以及自平衡率进行对比分析,并得出余电制氢计划这一运营方式更具经济性的结论。In order to comprehensively evaluate the economy of the microgrid system under different operation modes,this paper,from the perspective of the whole society,comprehensively analyzes the cost and benefit of the microgrid system under the two operation modes of surplus electricity online and surplus electricity hydrogen production.Considering the influence of different types and capacities of distributed power on the performance of microgrid system,this paper firstly studies the constant volume problem of distributed power in microgrid.Under the premise of satisfying the specific constraints,a two-level optimization model of microgrid system is established with the objective function of maximizing the comprehensive benefits of the whole life cycle.In this two-layer optimization model,adaptive particle swarm optimization algorithm is used to solve the optimal configuration of the system in the upper optimization model,and CPLEX solver is used to solve the optimal scheduling scheme in the lower optimization model.On this basis,the economic evaluation model of the whole life cycle is used to make a comparative analysis of the costs,benefits and self-balance rate under the optimal configuration of the specific example,and the conclusion is drawn that the operation mode of residual electricity hydrogen production plan is more economic.
