Abstract

For typical parks with electricity/cooling/hydrogen demand, this paper proposes an optimal configuration model of hydrogen-ice energy storage microgrid considering solid oxide fuel cell (SOFC) waste heat recovery, which aims to optimize the capacity of main components such as wind/light/hydrogen/ice/storage in the microgrid, so as to improve the economy. Firstly, the AC/DC hybrid and source driving load directly of the dual energy storage mechanism of photovoltaic DC electrolytic water hydrogen storage and wind AC power ice storage is designed. In order to improve the utilization rate of hydrogen energy, it is proposed to use the waste heat recovery of SOFC for cogeneration of cold and electricity. Considering the nonlinearity of the model proposed in this paper, the changeable operation states of electrolyzer, ice storage and other equipment, and the problem that the optimization algorithm is easy to fall into local optimization and difficult to find global optimization, an ABC-QPSO algorithm with strong global search ability is proposed to solve the model. Finally, taking a park in Guangdong as an example, through the comparative analysis of four schemes, the superiority of the model proposed in this paper is verified.
