This paper proposes a novel control strategy in multi-terminal DC (MTDC) grids with offshore wind generation based on the idea of generalized voltage droop (GVD). In the proposed strategy, the GVD characteristics are assigned to the voltage-regulating converter station, enhancing their control maneuverability and enabling them to perform necessary DC voltage control and power sharing tasks. By adjusting the coefficients of the corresponding GVD characteristic, a converter station can be operated in three operating modes, namely (1) fixed active power control mode, (2) conventional voltage droop control mode or (3) fixed DC voltage control mode. Results of simulations on a test four-terminal DC grid including two offshore wind farm and two AC grids show the capabilities of the proposed control strategy. Moreover, simulation results confirmed stable operation of the GVD control in transition from one operating mode to another.

A high gain DC-DC converter is proposed in this paper. This converter combines the basic boost converter with voltage doubler circuit to achieve high voltage gain with high efficiency. The novel topology makes use of a single switch to achieve high voltage gain. The voltage appearing across the switch is much lower than the output voltage. Hence, a low voltage rating switch with low on state resistance can be used for this converter. The operation of the converter is explained and steady state analysis is included. Voltage gain equation and expression for voltage across the switch is derived. Representative simulation results are included along with the preliminary experimental results.

Grid codes require wind farm to ride through disturbances such as faults and support the grid during such events. Doubly fed induction generator (DFIG) based wind farm with conventional design has limited capability to ride through severe asymmetrical faults due to low capacity of the rotor-side-converter (RSC). DFIG wind turbine with series grid-side converter (SGSC) can help to extend the operation areas during the fault and satisfy the future grid codes. This paper addresses the capacity design and coordinating control scheme of the SGSC-DFIG based wind farm to ride through the severe asymmetrical fault and support the power grid. Considering the control capability of the RSC and the requirements of the present grid code, the SGSC capacity can be minimized if it is employed to compensate part of the negative-sequence grid voltages. By coordinating the control of SGSC and the DFIG, the positive- and negative-sequence reactive current can be carefully regulated to support the grid and satisfy the code requirements. At the same time, the torsional oscillation of the generator shaft can be mitigated by the negative current control. Simulation results verify the effectiveness of the design and scheme.

This paper presents a simple and cost-effective stand-alone rapid battery charging system of 30kW for electric vehicles. The proposed system mainly consists of active front-end rectifier of neutral point clamped 3-level type and non-isolated bi-directional dc-dc converter of multi-phase interleaved half-bridge topology. The charging system is designed to operate for both lithium-polymer and lithium-ion batteries. The complete charging sequence is made up of three sub-interval operating modes; pre-charge mode, constant-current mode, and constant-voltage mode. The pre-charge mode employs the stair-case shaped current profile to accomplish shorter charging time while maintaining the reliable operation of the battery. The proposed system is specified to reach the full-charge state within less than 16min for the battery capacity of 8kWh by supplying the charging current of 78A. Owing to the simple and compact power conversion scheme, the proposed solution has superior module-friendly mechanical structure which is absolutely required to realize flexible power expansion capability in a very high-current rapid charging system.

This paper proposes a new design method of LCL-filter for three-phase PWM voltage source inverter. Maximum converter-side current ripple is calculated by defining different modulation section of the adopted PWM strategy. In this way, the method can be easily extended to different converter topology and PWM strategy. Then the result is used to determine converter-side inductance. Once it is fixed, current attenuation passing from converter to grid at switching frequency and reactive power limitation equations are synthesized to design the minimum grid-side inductance and the proper range of resonance frequency. Then according to adopted PWM converter voltage spectrum, choose final resonance frequency to avoid the harmonic frequency spectrum distribution. A design example is given and the simulation and experiment results demonstrate the effectiveness of the method.

While hysteresis current control offers the benefits of a fast dynamic response and inherent overcurrent protection, its variable switching frequency and inherent two-level switching response make it unsuitable for many applications. This paper presents a new approach for three-level hysteresis control of a single phase grid-connected inverter that overcomes these limitations. The strategy adjusts the hysteresis band magnitude in response to variations in the inverter average output voltage, to achieve constant switching frequency using only one hysteresis comparator and without requiring DC offset compensation or current error zero-crossing measurement. The inverter average voltage is also used to estimate the phase of the incoming grid voltage, to create a current reference for the regulator at any required power factor. The result is a robust sensorless hysteresis current regulator suitable for three-level grid connected applications that operates with a constant switching frequency.

In high power applications, in which the discrete power switches are mounted on separate heatsinks, an overload of a semiconductor device leads to a local excessive thermal stress and eventually to a failure of the system. Despite of a control strategy that ensures the even distribution of losses in the normal operation, a local thermal overload can arise due to failures in the electronics, in the cooling system, due to an inappropriate positioning of the semiconductor device, etc. In this paper, a new fault tolerant control approach is introduced to deal with this matter. When detecting increased thermal stress of one IGBT module, the switching strategy is altered in order to reduce the load of that particular IGBT module and to redistribute the losses and consequently the heat from the affected group or valve to the other switches. Hence, the temperature of the stressed switch is kept under the critical limit and the thermal overload is reduced. In such way the reliability and the lifetime of the converter is maximized even in case of thermal failure. In the proposed novel modulation concept, the balancing of the neutral point potential of the 3L-NPC Inverter is also ensured without any additional hardware.

In applications of modern power distribution with distributed energy resources, grid-tied energy storage systems (ESS) will be increasingly incorporated. Energy storage devices (ESD) such as lithium-ion battery or super-capacitor cells however have low DC terminal voltages. It is essential to develop a bidirectional DC/AC converter to interface ESS based on low voltage cells to the higher voltage grid without using high number of cells in series. In this paper a bidirectional current-fed converter with high frequency transformer isolation is proposed. In this proposed topology, a current source inverter (CSI) is used to interface to the grid. A DC/DC converter with High frequency(HF) transformer is used to feed the current to CSI. Low voltage and high voltage side of DC/DC converter can be either Push-Pull or Full-Bridge. The proposed topology has the advantage of reduced component count and simple control strategy. Simulation and hardware results have shown that the proposed circuit can work in charging and discharging of the ESS and the control strategy is effective.
