Application of flow battery energy storage system at the end of rural power grid

Abstract

The mobile energy storage power station based on the all vanadium flow battery has many advantages such as flexible layout, adjustable power capacity and high application efficiency. It can achieve effective support for active and reactive power at the end of the rural power grid and voltage and frequency regulation, and comprehensively improve the power supply capacity and quality of the end of the rural power grid. In order to select suitable application demonstration points to verify the above functions, a survey was conducted on the low voltage at the end of the rural power grid. Based on the experience of local staff and the comprehensive geographic factors of local monitoring system data, the end of a certain rural power grid was selected as the pilot area. The capacity of the transformer in the distribution station area was 50kW to supply power to approximately 50 households. The 50kW/100kWh all vanadium redox flow battery was selected as the energy storage system.
