The energy of the liquid flow energy storage system is stored in the electrolyte tank, and chemical energy is converted into electric energy in the reactor in the form of ion-exchange membrane, which has the characteristics of convenient placement and easy reuse , , , .
The establishment of liquid flow battery energy storage system is mainly to meet the needs of large power grid and provide a theoretical basis for the distribution network of large-scale liquid flow battery energy storage system.
is introduced, and the topology structure of the bidirectional DC converter and the energy storage converter is analyzed. Secondly, the influence of single battery on energy storage system is analyzed, and a simulation model of flow battery energy storage system suitable for large power grid simulation is summarized.
In the literature , a higher-order mathematical model of the liquid flow battery energy storage system was established, which did not consider the transient characteristics of the liquid flow battery, but only studied the static and dynamic characteristics of the battery.
Energy storage system can overcome the shortcomings of new energy by using its own characteristics and response ability to the power grid, and reduce the impact of its large-scale utilization on the power grid.
The positive and negative electrolytes are respectively stored in the liquid storage tank. Through the circulating pump, the electrolyte will reach the reactor unit from the liquid storage tank along the pipeline path. The electrolyte can exchange charge through the ionic membrane of the reactor, and the design is flexible.
