Supercapacitor energy storage system discharge strategies considering discharge power levels and DC grid voltage drop

This paper describes the calculation of the discharge parameters of supercapacitor energy storage systems on both sides of a DC/DC converter when both the DC grid and the energy storage system supply power to the consumer. In one discharge variant, the intensity of the discharged power of the energy storage system is regulated as a percentage of the full power of the consumer. In the second discharge variant, the voltage drop across the DC line is regulated by the discharging of the energy storage system. The case of an energy storage system connected to the DC grid very close to the consumer and the case where it is connected further away from the consumer are considered.
