In reference 24, for the FESS-UPS system, the designed extended state observer improved the charging efficiency and the proposed sliding mode control method reduced the oscillation of the outputted DC-bus voltage, and the oscillation at the switch state from the charging to the discharging was not suppressed.
Finally, the simulations and experiments are performed to validate the performances of the switch strategy used in the FESS-UPS system, and the results prove that the current/voltage peaks during the switching process are effectively mitigated, so the impact on the power converter caused by the state switch is suppressed.
For the normal switch strategy, the oscillation value of the DC-bus voltage reaches 136 V from the holding stage to the discharging stage. For the proposed switch strategy using the compensation model, the variation of the DC-bus voltage is reduced to 102 V during the switching process.
