Aiming at reactive power and harmonic current in the low-voltage distribution grid, a hybrid comprehensive dynamic reactive power and harmonic current compensator is designed. The shunt capacitors compensate the fundamental reactive power, the shunt APF eliminates the harmonics and the small amounts of load reactive power. But when they work in the same electric utility there exists resonance problem, in order to avoid resonance, the compensation character of hybrid compensation device under traditional strategies for current type nonlinear load were well studied theoretically and quantitatively by establishing mathematic model. A new current control strategy, which not only suppress line-side harmonic current and reactive power but also avoid resonance between shunt capacitors and line-side impedance, was put forwards. And a new compensator method which the APF only compensates 1/2 reactive power of each shunt capacitor was provided, due to the APF could compensate both inductive and capacitive reactive power. It lower the capacity of APF, and reduce the cost. Simulation show that the new control strategy and the new compensation method work stable, fleetly and effectively eliminates most harmonics and compensates majority reactive power.

This paper proposes a smart charger to mitigate the charging impact of Electric Vehicles (EVs) on power grids. The proposed smart charger uses the parameters measured from the power grid, the EV charger and the EV battery pack to adjust the charging current of the proposed charger. Fuzzy control is used in this paper to integrate these measured parameters into designing a smart charger prototype with rated power 200W. Experimental results verify that the proposed charger can automatically adjust the charging current corresponding to the variations of power grid and EV. Test case analyzes the impact of 100 EVs with rated power 7kW charging simultaneously in a community. Test result shows that the charging impact of EV can be effectively mitigated by the proposed smart chargers. Since the proposed smart charger can be realized without the centralized control systems and information exchanges between EV chargers, an entirely distributed control scheme for EV charger can therefore be effectively implemented.

Modular multilevel converter (MMC) has become a promising multilevel topology for high-power applications in recent years. This paper proposes a novel capacitor voltage balancing method for an improved MMC circuit with a three-level neutral-point-clamped (NPC) module connected upper arm to lower arm in each phase, which possesses the merit of saving two half-bridge sub-modules (SMs) for each phase compared with the conventional MMC topology when generating the same number of output voltage levels. To make sure that the output voltage of this novel MMC keeps the same with that of the conventional MMC, this paper combines phase-shift carrier PWM (PS-PWM) with phase-opposition-disposition carrier PWM (POD-PWM) as the modulation strategy. Further, the proposed capacitor voltage balancing method based on adjusting the modulation wave mainly focuses on the neutral point voltage balancing of the NPC module and the voltage balancing between the NPC module and arms. Simulation results verify the effectiveness of the proposed capacitor voltage balancing method.

An improved RCD snubber for solid-state circuit breaker (SSCB) is proposed in this paper in a low-voltage DC microgrid to protect SSCB against overvoltage caused by its tripping at the occurance of a DC-bus fault. Instead of relying mostly on the snubber capacitor to absorb the fault energy like commonly-used RCD snubbers, the proposed RCD snubber uses the snubber diode and an additional snubber resistor to form a separate path, which allows most of the energy to exhaust itself away from the snubber capacitor. In this way, the overvoltage across SSCB can be suppressed without increasing value and capacity of snubber capacitor, while the fault energy can also be quickly spent. Snubber process is discussed detailedly at a line-to-line fault to prove its effectiveness. Also, a design method is presented because former studies on parameter design of RCD snubber usually aim for converter appliance and cannot be directly applied on the proposed RCD snubber, which must be able to operate under fault current and thereby lays more stress in the peak value damping of overvoltage instead of quick suppression. Finally, simulations are conducted to prove its effectiveness in overvoltage suppression and fault current absorption.

This study proposed using the existing structure of parallel-type PV system data acquisition and monitoring technology in National Taipei University of Technology (NTUT) to construct a smart cloud maintenance and management system. At the project node computer end (central database configuration tool web server), the functions of smart cloud maintenance and management are added, such as historical records, reporting records, reporting summary, supplementary alarm, video, reports generation, and scheduling. Currently, besides being implemented at NUTU, the parallel-type PV system in National Longtan Senior High School is connected to the project node, and uses maintenance and management functions. The management system of this project can connect all public PV systems to the smart cloud maintenance and management system for information sharing, coordinated control, and update of PV data, thus achieve resource sharing.

The paper proposes a new active power conversion system (APCS) applied in microgrid for the connection and flexible power transmission between the main grid and the microgrid and power quality improvement. APCS is composed of three voltage sourced converters (VSCs), ie., main-grid VSC, shunt VSC, and series VSC, which all adopt modular multilevel converter (MMC) topology. The paper analyzes grid-connected and island operating modes of the APCS and proposes control strategy for every MMC-VSC. The models of the microgrid and the APCS are built in PSCAD/EMTDC, and the operating modes and control strategies are achieved to verify the functions of the APCS in power quality improvement and flexible power transmission.

The 3-phase current form of a permanent magnet synchronous motor under Field Oriented Control (FOC) will be influenced by both motor harmonics and the Electronic Control Unit (ECU) deviations. In this work, the current shape deformation due to the influence from the specific ECU failures, including transistor dead time and current measurement error will be introduced and simulated. As the torque ripple under the non-sinusoidal current will increase compared to the one under sinusoidal current, the torque ripple robustness against current harmonics can be considered as an important design concept when optimizing the electromagnetic circuit of PMSMs. This paper builds up a connection between the torque ripple and the static inductance by introducing coenergy for torque approximation purpose. This method will be approved by the Finite Element Analysis.

A SOC-based charger for the LiFeO4 battery pack is implemented in this paper. The main circuit is a full-bridge phase-shift converter. The user can select the charging strategy and observe the state of charge (SOC) of the battery from the operation interface. Moreover, the proposed charger system communicates with the battery management system via the I2C interface, and generates the charging current according to the estimated SOC and the selected operation mode. In addition, the charging current is kept at preset constant value by modulating the phase-shift amount to shorten the charging time and improve the battery lifespan. Furthermore, there are three charging strategy for user selection. All the experimental results are also provided.

This paper presents the study and implementation of an isolated bidirectional resonant converter with natural commutation. It can be operated in natural commutation without additional control. The proposed isolated bidirectional resonant converter works like a DC transformer, which can be applied for DC micro-grid systems. Compared with the conventional phase-shifted full-bridge converter and current-fed full-bridge converter, the proposed resonant converter presents better performance in efficiency, control and cost. The operating principles and design considerations are discussed and analyzed in details. Finally, a laboratory prototype converter has been built and tested to verify the feasibility of the proposed scheme. High efficiency and simple control can be achieved.
