Multi-objective optimal dispatch of energy router considering the efficiency of microgrid

As a large-scale, integrated multi-energy network characterized by the prominence of multi-energy microgrids (MG) becomes a major trend in the development of power systems, the energy router (ER) gradually becomes the core component of multi-energy interconnection. In this paper, AC/DC hybrid MG based on magnetically coupled ER are studied, and the operation models of photovoltaic, wind turbine, flexible load and energy storage devices are considered. A multi-objective optimal dispatch model based on ER is established, with operating cost and operating efficiency as optimization objective functions, and an improved non-inferior classification genetic algorithm (NSGA-II) is employed. Through the simulation calculation in different cases, compared with the traditional dispatch scheme, the microgrid scheduling scheme based on ER can reduce the operating cost of MG and also improve its stability on the condition of greatly improving the consumption capacity of renewable energy.
