The DC bus voltage, battery charging cycle, and supercapacitor SoC restoration are improved significantly with the proposed voltage compensation mechanism. Fig. 13. Comparison of charging and discharging cycle for the battery. Fig. 14.
An energy management strategy for lithium-ion batteries and SCs in DC microgrids is proposed, which improves system control accuracy and reliability and enables optimal power distribution of the lithium-ion battery and SC; moreover, the bus voltage compensation is designed to eliminate voltage deviations under the control loop.
Since the proposed voltage compensation term guarantees autonomous bus voltage restoration, the supercapacitor state of charge (SoC) remains at nominal value without violation while it only buffers fluctuating power. However, the battery only compensates for the nominal power demand.
The nominal SoC of the supercapacitor is set to 0.5. Due to the DC bus voltage deviation, the conventional approach is unable to restore the nominal SoC throughout the entire simulation time. However, the proposed voltage compensation mechanism is capable to restore the nominal SoC of the supercapacitor.
In the proposed control approach, the change in load power demand is split into steady-state and transient parts where the battery provides only the steady-state part and the supercapacitor buffers the transient part.
The proposed is an interleaved PFC converter with a TPTZ digital compensation. The FBPS converter adopts an average switching model to derive a small-signal model. The proposed TPTZ method has 96 %, efficiency when charging mode at 100 % load. This study proposes a 1 kW power converter of the lithium battery charging system for electric vehicles.
