TL;DR: In this article, an overview of microgrid configurations is given, and possible structure options and control methods of DER units are presented, which is followed by the descriptions of system controls and power management strategies for AC microgrids.
Abstract: The increased penetration of Distributed Energy Resources (DER) is challenging the entire architecture of conventional electrical power system. Microgrid paradigm, featuring higher flexibility and reliability, becomes an attractive candidate for the future power grid. In this paper, an overview of microgrid configurations is given. Then, possible structure options and control methods of DER units are presented, which is followed by the descriptions of system controls and power management strategies for AC microgrids. Finally, future trends of microgrids are discussed pointing out how this concept can be a key to achieve a more intelligent and flexible power system.

TL;DR: In this article, a new approach to battery life estimation for lithium-ion batteries used in plug-in hybrid electric vehicles (PHEVs) applications is presented, whose development is built upon a weighted ampere-hour throughput model of the battery, is based on the novel concept of severity factor map which captures and quantifies the battery damage caused by different operating conditions.
Abstract: This paper presents a new approach to life estimation for lithium-ion batteries used in plug-in hybrid electric vehicles (PHEVs) applications. A new framework for battery life estimation is developed which investigates the effects of two primary factors of battery life reduction in PHEVs applications, namely, depth of discharge (DOD) and temperature (Tbatt), under typical driving conditions, driving habits, and average commute time of typical user over a year. This framework, whose development is built upon a weighted ampere-hour throughput model of the battery, is based on the novel concept of severity factor map which captures and quantifies the battery damage caused by different operating conditions. The proposed methodology can be a suitable tool to estimate battery life in terms of miles/year on-board of the vehicle.

TL;DR: In this article, a novel approach to fuel cell modelling is proposed, which is obtained from manufacturer datasheets and is able to represent the behaviour of any hydrogen fuel cells, and is integrated in SimPowerSystems and used in the simulation of a fuel cell vehicle.
Abstract: In this paper, a novel approach to fuel cell modelling is proposed. The model is obtained from manufacturer datasheets and is able to represent the behaviour of any hydrogen fuel cells. The simulation results are as expected with an error in the range of ±1%, provided a controlled stack internal humidity. The procedure to extract data from fuel cells datasheet is described along with the method to estimate cell’s parameters. The model is integrated in SimPowerSystems (SPS) and used in the simulation of a fuel cell vehicle. The vehicle is modelled with the same characteristics as the Honda FCX-Clarity. The performance obtained from the vehicle model is close to reality in terms of fuel consumption, maximum speed and acceleration.

TL;DR: In this paper, a six-switch topology inverter with symmetrical pulse width modulation (PWM) switching technique is used to filter out unwanted harmonics and produce a sinusoidal AC current.
Abstract: Detailed analysis, simulation and hardware results of grid connected inverter with maximum power point tracker and power factor control in Malaysian climate are presented. A six-switch topology inverter with symmetrical pulse width modulation (PWM) switching technique is used. A low-pass filter is incorporated in the circuit to filter out unwanted harmonics and produce a sinusoidal AC current. Low total harmonic current distortion at the inverter output can be achieved. The three-phase PWM switching pattern was developed using Xilinx FPGA. The developed system is also capable of adjusting the power factor to unity. A 3 kVA power transformer with a 1:2 ratio is constructed to provide galvanic isolation for better circuit performance and circuit protection. Hardware results for proposed solar photovoltaic inverter configuration interconnected to the grid are also presented. From the experimental results, it is confirmed that the harmonic distortion of the inverter output waveform is within the limits laid down by the utility companies.

TL;DR: In this article, the advantages and drawbacks of four potential PHEV charger topologies were compared based on their operations through simulation and experiments, and it was concluded that a full-bridge based charger is the most favourable choice among the four available topologies due to its power capability, soft switching capability, low electric stress, high efficiency, but slightly elevated cost.
Abstract: The battery charging system is a critical part of a plug-in hybrid electric vehicle (PHEV). The efficiency, charging speed, and cost of such chargers are crucial to the commercialisation of PHEVs. In this paper, the advantages and drawbacks of four potential PHEV charger topologies were compared based on their operations through simulation and experiments. Their electrical stress, efficiency, cost, and the feasibility were discussed in detail. It was concluded that a full-bridge based PHEV charger is the most favourable choice among the four available topologies due to its power capability, soft switching capability, low electric stress, high efficiency, but slightly elevated cost.
