The present disclosure relates to a fracturing system comprising a functional unit, an electricity supply unit and an energy storage unit. The functional unit is configured to perform procedures of fracturing operations. The electricity supply unit is electrically connected with the functional unit and is configured to supply electrical energy to the functional unit. The energy storage unit is respectively electrically connected with the electricity supply unit and the functional unit, and is configured to store electrical energy from the electricity supply unit and supply electrical energy to the functional unit. According to the present disclosure, the energy storage unit of the fracturing system can store surplus electrical energy of the electricity supply unit and supply electrical energy to the whole fracturing system when needed, playing a role of energy storage as well as peak shaving so that the generator set and the like can maintain economic working condition for a long time, thus the system can be safe, stable, and achieve improved efficiency and economy. In addition, it is possible to generate electricity from non-carbon sources for fracturing operations and minimizes the use of internal combustion engines, which is more environment-friendly. The present disclosure can also reduce the number of generator sets and the space occupied by the generator sets so as to reduce the construction cost of fracturing operations.
