Parking management systems are emerging into the global market to solve issues with finding car parks. Existing systems claim to have partially discovered ways to overcome this challenge. However, they are neither fully complete nor robust enough to be commercialised. The current systems installed can sometimes mislead the drivers by not providing fixed locations to the users. Furthermore, the installation costs for such systems are quite high, and they require expensive maintenance due to corrosion, dust, and other environmental factors. This paper presents an intelligent parking solution that allows users to reserve car parks and guides them to the free car park at the same time. The solution presented not only helps in substantially reducing the traffic in search of a parking space but also increases the occupancy by making the management of parking space, a precious resource in metro cities, easy. This significantly minimises the impact of environmental issues by reducing the carbon footprints.

Several portable applications, such as small electric vehicles and power tools, often require the use of direct current (DC) motors that significantly differ from one to another in terms of power, torque, and driving techniques. New market requirements of these applications suggest the implementation of smart user interfaces that may allow the introduction of those devices in the new Internet of Things paradigm by making them connected. This paper discusses the design and verification of a flexible platform able to drive different types of DC motors that is also provided with a Bluetooth connection for remote control and monitoring. As the platform can drive different motors with different driving techniques, it provides standardisation and cost reduction in the production of a set of tools. Two gardening tools are used as case study to verify the design and flexibility of the board. Both tools are successfully controlled and monitored with a wireless connected remote user interface.

Industrialized countries with a stable electric utility network will typically have 12 to 18 multi-cycle (2 to 3 cycles) power quality events per year which could disrupt production in high-tech manufacturing facilities. The choices of power protection systems are often related to capital cost and operational cost. Capital cost may include the cost of footprint, and operational cost will be dominated by efficiency but include maintenance requirements. Proper consideration of the utility performance and load requirements can yield a solution that saves millions of dollars for a large facility over its life. The solution maybe a single conversion UPS that is 99% efficient, and uses ultracapacitors as energy storage, giving an extremely small footprint and long life. Ultracapacitors promised a lot 10 years ago, but have not become ubiquitous and remain in a niche market sector. ABB can certainly be regarded as a market leader in ultracapacitor based equipment, having supplied over 300MVA of equipment since 2007.

New testing and development procedures are needed to address topics like power system stability and control in the context of grid integration of rapidly developing new smart grid technologies. The main focus of this paper is to analyze the impact of the grid integration of smart grid equipment from the component perspective and from the system perspective, respectively and to propose appropriate testing methods. In order to cope with the challenges introduced by the integration of the afore-mentioned technologies, a holistic testing infrastructure needs to be considered and set up. For this purpose, the holistic multi-domain design concept is proposed to fulfill the needs of new smart grid technologies testing and development phases. The holistic Power System-in-the-Loop testing setup proposed by this paper has the advantage of a testing environment, which is very close to field testing, includes the grid dynamic behavior feedback and is risks-free for the power system, for the equipment under test and for the personnel executing the tests.

In power-hardware-in-the-loop (PHIL) digital simulation testing, a power device, also known as device-under-test (DUT), is virtually exchanging power with a power amplifier governed by the reference signals coming from the point of interface (POI) in the power system implemented on a digital real-time simulation platform. Indeed, the power amplifier (also known as grid simulator) is the integral of any PHIL testing, and its dynamics are greatly impacting the accuracy of the PHIL testing. The dynamics of an industrial power amplifier is certainly not an ideal transfer function, i.e., unity. In fact, it is going to degrade the accuracy of the testing especially when the interested frequency range of the power system studies is within the frequency response of the power amplifier's dynamics. Consequently, having an industrial power amplifier's dynamics is very helpful in order to judge the accuracy of the PHIL testing. In this paper, experimental results of an industrial power amplifier have been used, and mathematical linear discrete-time models of the industrial power amplifier have been extracted using different linear system identification methods. Designing input signals, pre-processing data, estimating time delay, estimating model order and parameters, calculating confidence intervals, representing frequency-domain of models, and validating different models are shown in this paper. ARX, ARMAX, BJ, and OE estimated models, which benefit from prediction error method (PEM), are employed in this paper.

In this paper, the predictive control of DC-link current based on the IPMSM discrete equation for electrolytic capacitor-less inverter is proposed. In electrolytic capacitor-less inverters, electrolytic capacitor and power factor correction circuit are not used. Therefore, it is necessary to maintain both the input power factor and the motor control by controlling the inverter. Instantaneous voltage control has been proposed as a control method to achieve both motor control and input power factor improvement. In the instantaneous voltage control method, the DC-link current driving the motor is controlled. However, control error occurs in the DC-link current due to the sampling error in the motor current. Due to this control error, a resonance current is generated in the inductance and the DC-link capacitor. The predictive control of DC-link current proposed in this paper reduces this control error. The effectiveness of the proposed method is confirmed through simulation.

Of late, the idea of hybrid microgrid has drawn immense attention among the recent researchers. Especially in a hybrid microgrid, the interlinking converter (ILC) is considered responsible for appropriate power management between the ac and dc sides. In this paper, a topological vision of ILC is presented along with its control algorithms. The proposed three-port topology, viz. dc grid, ac grid and energy storage gives operational flexibility for different bidirectional power flow modes. It offers inherent dc fault tolerance without dc-breaker, reduced volt-ampere rating of the switches and lesser conduction and switching losses. Utilization of low-voltage modular battery stacks makes the topology efficient, reliable and cost-effective. MATLAB simulation results are presented for validation of the proposed work.

To reduce the capacitance of the DC-link capacitor in an AC-DC-AC system, a single-phase to three-phase electrolytic capacitor-less inverter is proposed. The inverter is used to control both the motor and source currents. In particular, it is necessary to sinusoidally control the source current to meet the source current harmonics guideline. The DC-link voltage becomes an absolute value of the source voltage and is almost zero near the zero crossing. As the output voltage is also zero near the zero crossing, the motor current response deteriorates in the method of controlling the source current sinusoidally. The motor current near the zero crossing flows because of the back electromotive force, and the copper loss is significantly large, particularly in the high-speed region. This paper analyzes the motor current response in the zero-output-voltage region and proposes a method to suppress the motor current increase. The proposed method is validated by conducting simulations and experiments.
