“…Mode I and Mode III are used to configure the Bidirectional DC/DC converter in a Buck mode (charging mechanism). This mode has been used in previous work to decrease the voltage of the external Boost converter module from 36 VDC to 18 VDC and charge the Supercapacitor [17]. Whereas to discharge and buffer the voltage and current for an electrical All-Terrain Vehicle (ATV) motor, we will use Mode II and Mode IV.…”

Buck and Boost modes, which working alternately. Hence, it has two output directions: Buck mode for decreasing the voltage and Boost mode for increasing the voltage at certain levels. In this work, we applied a non-isolated topology of the Bidirectional DC/DC converter for electric vehicle, that is mini all-terrain vehicle (ATV). We set a Buck mode to charge the Supercapacitor when the battery current and the Supercapacitor voltage are lower than considered level. Whereas the Boost mode was used to discharge as well as buffer the mini ATV when the battery current and the Supercapacitor voltage are higher than considered level. The discussion of Buck mode has been presented in previous work, so in this work, we focus on the Boost mode analysis only. This mode is set to increase the Supercapacitor's voltage. The Supercapacitor with 25 VDC/8 Farad was used as the secondary main power inside the 22.2 VDC / 5000 mAh LiPo battery of the mini ATV motor. The mini ATV requires 36 VDC to work. Thus, it must be boosted first from 22.2 to 36 VDC using an external Boost converter. Moreover, it must be maintained at 36 VDC. Based on the requirement, we first design the bidirectional DC/DC converter involving the mathematical calculation and then simulate it into LTSpice®. The Printed-Circuit Board is then lay-outed and mounted. Later, we connected the designed system to mini ATV motor and tested the performance as well. According to the laboratory test, the Bidirectional DC/DC converter can increase (Boost) the voltage of the Supercapacitor from a certain level to 36 VDC. On the other hand, it can maintain 36 VDC. The central control in this system uses the STM32F4 Microcontroller, while the battery monitoring system employs the STMStudio.

“…When the frequency fluctuates, the supercapacitor is controlled to release its energy to participate in frequency regulation, thus the supercapacitor can get charged in the normal condition. Considering that constant power charging mode [31,32] has more advantages in charging time and charging efficiency, it is used in the supercapacitor getting charge from the power grid by the external charging device [33][34][35].…”

The large-scale application of wind power eases the shortage of conventional energy, but it also brings great hidden danger to the stability and security of the power grid because wind power has no ability for frequency regulation. When doubly-fed induction generator (DFIG) based wind turbines use rotor kinetic energy to participate in frequency regulation, it can effectively respond to frequency fluctuation, but has the problems of secondary frequency drop and output power loss. Furthermore, it cannot provide long-term power support. To solve these problems, a coordinated frequency control strategy based on rotor kinetic energy and supercapacitor was proposed in this paper. In order to ensure the DFIG provides fast and long-term power support, a supercapacitor was used to realize the droop characteristic, and rotor kinetic energy was used to realize the inertia characteristic like synchronous generator (SG). Additionally, the supercapacitor is also controlled to compensate for the power dip of the DFIG when rotor kinetic energy exits inertia support to avoid secondary frequency drop. Additionally, a new tracking curve of DFIG rotor speed and output power was adopted to reduce the power loss during rotor speed recovery.
