Droop control is an effective power sharing control scheme of distributed generation (DG) inverters in islanding AC microgrid, which can stabilize the grid as long as the distributed generation systems have sufficient residual power. On the contrary, many loads have equipped with power conversion circuits in front to improve the operational efficiency, e.g. air conditioners and LED lighting, which in fact can also provide the regulation function for stabilizing grid during transient process. This paper therefore proposes a ramp control theory for insensitive active power electronics loads in microgrid to control grid frequency together with DGs. The load ramp control method can effectively reduce the frequency variation especially when microgrid enters islanding mode from grid-tied mode, meanwhile the ramp control can release the burden of fast energy storage systems in microgrid and then reduce the construction cost of microgrid. Control wise, load ramp control is also a communication-less control theory, which only assumes the local information. Matlab simulations and experimental results are presented to show the effectiveness of the proposed theory in islanding microgrid.

The need for multidisciplinary virtual prototyping in power electronics has been well established however design tools capable of facilitating a rapid, iterative virtual design process do not exist. A key challenge in developing such tools is identifying and developing modelling techniques which can account for 3D, geometrical design choices without unduly affecting simulation speed. This challenge has been addressed in this work using model order reduction techniques, and a prototype power electronic design tool incorporating these techniques is presented. A relevant electro-thermal power module design example is then used to demonstrate the performance of the software and model order reduction techniques. Five design iterations can be evaluated, using 3D inductive and thermal models, under typical operating and startup conditions on a desktop PC in less than 15 minutes. The results are validated experimentally for both thermal and electrical domains.

Because of their characteristics, which have been continuously improved during the last years, Lithium ion batteries were proposed as an alternative viable solution to present fast-reacting conventional generating units to deliver the primary frequency regulation service. However, even though there are worldwide demonstration projects where energy storage systems based on Lithium-ion batteries are evaluated for such applications, the field experience is still very limited. In consequence, at present there are no very clear requirements on how the Lithium-ion battery energy storage systems should be operated while providing frequency regulation service and how the system has to re-establish its SOC once the frequency event has passed. Therefore, this paper aims to investigate the effect on the lifetime of the Lithium-ion batteries energy storage system of various strategies for re-establishing the batteries' SOC after the primary frequency regulation is successfully delivered.

Conventional offshore wind farms with medium voltage (MV) AC grid require low frequency step-up transformer to boost the output voltage of the wind turbine. In order to eliminate the bulky MV step-up transformers in MVAC grid, the use of a MV step-up DC/DC converter in MVDC grid is an attractive alternative. In this paper, two modular MV step-up DC/DC converter topologies that combine multiple modules of step-up resonant circuits and high frequency high gain rectifiers are proposed for MVDC grid in wind energy system. Due to the combination of multiple step-up resonant circuits and the high gain rectifiers, the proposed converters are able to achieve high voltage gain without using large turns ratio high frequency step-up transformers. In addition, ZVS turn-on ZCS turn-off are achieved on the inverter side switches to minimize the switching losses. The switching frequency is varied to regulate the output medium voltage for different wind speed conditions. The description and the operating principles of the proposed converter are provided in this paper. Results on a 5MW, 3.3kVac/40kV wind turbine system are presented to highlight the merits of this work.

Differences between a dc link choke versus an input line reactor in an adjustable speed drive can be examined based on several different aspects of drive performance, including harmonic mitigation, dc bus voltage drop, operation during voltage imbalance, cost of the reactor, electric surge protection, and operation for different types of system grounding. Of these performance aspects, harmonic mitigation, bus voltage drop, operation during voltage imbalance, and cost are well understood in prior art. In this paper, the effectiveness of dc link chokes and input line reactors for both surge protection and common mode (CM) issues on different types of system grounding is examined. The harmonic performance of each reactor type as well as the relative dc bus voltage drop are also reviewed for completeness.

DC micro-grids are considered as a friendly way to integrate renewable energy resources as well as distributed energy storage systems. With high penetration of power electronic converters in DC micro-grids, the control strategies of DC micro-grids can be very flexible. However, the line loss is relatively high at the same time. Thus, a proper optimal power flow (OPF) strategy is needed for DC micro-grids to minimize the line loss. Different from OPF for conventional grids, OPF for micro-grids should not require prior knowledge of grid structure and line impedance because power sources and loads may have frequent reconfiguration in grid architecture and the extendibility of the grid needs to be taken highly into consideration. In this paper, a control strategy for OPF in DC micro-grids is proposed. It is based on conventional hierarchical in DC grids with low bandwidth communication. The key point is an improvement in the secondary control strategy. The proposed OPF strategy needs neither knowledge of grid structure nor operating condition. A 400V microgrid simulation model is presented to verify the proposed method.

Modular multilevel converter (MMC) is being considered as the next generation converter among multilevel topologies and by introduction of MMC, a new era has opened to the field of medium- and high-voltage, high-power converters. Sizing the passive elements and design of the converter and its performance evaluation is thus of great importance for researchers in this area. The present paper performs a steady-state analysis of the modular multilevel converter (MMC) based on average model. The magnitudes and phase angles of current and voltage quantities are calculated. The equations are solved for different components of the circulating current and submodule voltage, and the resonance behavior in circulating current harmonics is investigated. Based on resonance behavior of circulating current harmonics, a guideline is given to choose the magnitude of submodule capacitance and arm inductance. A model is developed in MATLAB/Simulink environment in order to verify accuracy of the calculations done.

This paper presents a novel prototype of a timesharing frequency doubler principle-based current-fed zero current soft-switching (ZCS) high frequency resonant (HF-R) inverter for inductive power transfer (IPT) systems. The newly-proposed ZCS HF-R inverter is suitable for producing a higher frequency resonant current with switching power loss reduction by using a middle-class switching frequency insulated-gate-bipolar-power transistor (IGBT) for the IPT systems. In this paper, the performances of the newly-proposed ZCS HF-R inverter are demonstrated in experiment, after which the feasibility of the high frequency-link IPT power conversion circuit is discussed from a practical point of view.

Microconverters used for modular photovoltaic (PV) power conditioning systems require high efficiency over a wide input-voltage range. This paper introduces a series resonant converter through hybrid operation to meet this requirement. Under all input voltage conditions, the converter can achieve zero-voltage switching (ZVS) and/or zero-current switching (ZCS) of the primary-side devices and ZCS and/or ZVS of the secondary-side devices. The topologies and the three operation modes are introduced firstly. Especially, the steady state analysis based on the steady trajectories are presents in details. The design procedures of the power state are also introduced. The experimental results based on a 300-W prototype are given with 98.1% peak power stage efficiency and 97.6% CEC efficiency including all the auxiliary and control power under the 30V input voltage condition.

Bridged-T controller attains the advantages of both the open and closed loop controllers. It has the fast dynamic response feature of the open-loop controller and zero steady state error feature of the closed loop controller. The controller has been designed to generate sine, triangle and square waveforms with and without DC offset. The system has been simulated and experimentally implemented in real time using digital signal processor. Simulation and experimental results are in close agreement.
