The Grid-scale/Utility Scale Battery Energy Storage Systems (BESS) industry in Sao Tome and Principe is currently in its nascent stage. However, the country has been making significant strides in the development of renewable energy sources, which has led to an increase in the demand for BESS.
The hydraulic station is also known as the hydraulic pump station. The motor drives the oil pump to rotate. The pump absorbs oil from the oil tank and then discharges the pressure oil. Mechanical energy is converted into pressure energy of hydraulic oil. The hydraulic oil is regulated by the hydraulic valve in terms of direction, pressure and
