摘要：
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. © 2021, Power System Technology Press.
