Abstract
A hybrid energy storage system (HESS) and method of controlling a HESS is provided. The HESS comprises a common direct current (DC) bus having a DC bus voltage, an energy storage device electrically coupled to the common DC bus, a power device electrically coupled to the common DC bus, and a controller in operable communication with the energy storage device, the power device and the common DC bus. The controller is configured to, when the energy storage device is charging, increase a power device charging current if an energy storage device charging current is greater than a charging limit for the energy storage device, and when the energy storage device is discharging, increase a power device discharging current if an energy storage device discharging current is greater than a discharging limit for the energy storage device. The HESS can be part of a power system.
