The utilization of distributed generators, renewable energy, and energy storages boosts the microgrid development. Among various microgrids, the building microgrid (BM) tightly related with our daily life is also experiencing the improvement. One of the most obvious changes for the BM is the penetration of DC sources and DC loads, which forms the hybrid AC/DC BM. Because of the relatively small space and people density, the arc hazard should be paid more attention for buildings. In the meantime, the development of hybrid AC/DC BM will make the arc analysis more complicated, in which the AC and DC sections are closely interlinked. As the core interlinking part, the interlinking AC/DC buses are important to the safety guarantee of the hybrid AC/DC BM, which requires the main concern in the arc analysis. For the safety maintenance, this work firstly analyzes the hybrid AC/DC BM. Based on the arc current and the incident energy, an arc analysis flow is then designed for the interlinking AC/DC buses. Through the respective analysis for the interlinking AC and DC buses, a linear relationship is detected between the AC/DC loads and the arc current as well as the incident energy. By comparisons between the interlinking AC bus and DC bus, the qualitative and quantitative results are also illustrated for their arc differences. With the larger value, the increasing ratio of DC arc current could be employed as the detection signal. As larger loads cause larger arc current and incident energy, distributed loads are preferred to aggregated loads.

Energy efficiency is a main requirement in power converters used in domestic electrical goods including lighting. Using DC at home and DC-microgrids are relatively new concepts proposed to overcome the problems with energy efficiency. DC-microgrids are local energy networks which consist of renewable energy sources and storage systems. In many modern white goods, typically advertised as inverter driven, there is an AC-DC converter in the power drive train starting from AC 230V, 50Hz. Most domestic white goods, including energy efficient lighting are internally DC-driven and based on multiple DC-DC converters. Overall efficiency of a domestic appliance is determined by the multiplication of the efficiencies in each conversion stage. If the first stage of AC-DC conversion is not used, by feeding it from a DC source such as solar energy, end-to-end efficiency (ETEE) will be increased. Energy engineers are now getting ready to use DC-microgrid techniques. In this project where LED lighting loads are to be fed by solar or other renewable energy DC sources, 12V LED lighting is an excellent starting point, since LED lamps operate from plus or minus DC sources of widely varying DC values. We are developing a new technique, Supercapacitor Assisted LED (SCALED) lighting system powered by DC bus fed directly from solar panels, in which a supercapacitor (SC) bank is to be used to buffer short-term energy supply interruptions. This project derives from the patented SCALDO technique.

A novel soft-switching high step-down forward (SSHSDF) converter is proposed in this paper. The proposed converter consists of two two-switch high step-down forward cells (TS-HSDFCs). Their inputs and outputs are cascode and parallel connected, respectively, to share the input voltage and output current. The two switches of the proposed SSHSDF converter can also be turned on under zero-voltage switching (ZVS) condition. The proposed converter is thus suitable for high input voltage, high output current and high efficiency applications. Moreover, based on the operating principle of the proposed converter, all the features of the proposed can be achieved. Finally, a switching frequency 100 kHz and output power 200∼1000 W prototype of proposed converter is implemented. The theoretical analysis is thus verified by experimental results. It shows that the proposed converter has the highest efficiency of 95.6 %.

Although adaptive control has been widely studied and its effectiveness in control performance has been confirmed in scientific papers, applications to industrial machines are not widespread. This study verifies its effectiveness to not only motion trajectory tracking performance but also energy consumption with an industrial machine testbed. Because adaptive control adjusts its control parameters to ideal values, less energy consumption is expected while maintaining control performance. First, this paper presents a design of discrete-time adaptive control based on one of the authors' previous work. Next, contouring performance and energy consumption are compared to a conventional controller including proportional-derivative control and a robust observer. A typical repetitive circular motion of a machine tool feed drive with/without cutting tasks is employed for experimental comparison under several control system poles.

In this paper, stability of current control of battery energy storage system (BESS) connected with a diesel generator for a stand-alone microgrid are analyzed in four cases. The stand-alone microgrid system consists of 50kW BESS, 50kW diesel generator and controllable loads, where BESS is composed of 115kWh battery bank and 50kW DC-AC inverter. The four cases are 1) BESS with a stiff grid 2) BESS with the diesel generator 3) BESS with passive damping + diesel generator 4) BESS with active damping + diesel generator, and their stabilities are analyzed in the frequency domain and discrete time domain. Demonstration site for the stand-alone microgrid is constructed and comparative analysis for the four cases are verified through simulation and experiments, where experimental results show a good agreement with the analysis.

Megahertz (MHz) wireless power transfer (WPT) has been widely studied due to its lighter and more compact system and higher spatial freedom. This paper proposes a design methodology of the power receiver with high efficiency and constant output voltage in MHz WPT systems. The power receiver consists of four parts, the receiving coil, the Class E rectifier, the buck converter and the DC load. Firstly, the inductance, equivalent series resistance (ESR) and the coupling coefficients are formulated based on the physical model of the coupling coils. The Class E rectifier and the buck converter are also derived and analyzed. Secondly, the receiving coil and the Class E rectifier are designed and optimized simultaneously to maximize the efficiency while the buck converter is designed to works in a self-regulation mode to provide the constant output voltage. The system parameters design is formulated as an optimization problem and solved using the Genetic Algorithm (GA). Finally, simulation tool Advanced Design System (ADS) is used to verify the proposed design methodology.

In this paper, a novel two-switch three-phase LLC resonant circuit is proposed. The proposed circuit can reduce the input harmonic current of the AC/DC interface of microscale wind turbine generator. Thus, the vibration and noise of the three-phase wind turbine can be decreased and the life span of the wind turbine can be increased. Based on the proposed converter, the primary two switches have zero-voltage switching and the secondary two diodes have zero-current switching. In addition, the three-phase power factor correction can be achieved in both transient and steady states via two-switch LLC resonant circuit without using phase-locked loop and synchronous frame d-q axis control. The maximum power point tracking of wind power system also can be achieved through the voltage control oscillator and hill climbing searching control. Finally, some experimental results are offered to verify the validity of the proposed AC/DC interface of the microscale wind turbine generation system.

Sustainable building energy management is inevitable in order to reduce global energy demand. For this purpose, building energy management systems need to know the expected behavior of building automation systems, energy production units, or thermal dynamics. Designing the underlying models by domain experts might be a complex and expensive task. However, the models are already inherent in the growing amount of available monitoring data. Thus, this work proposes a framework utilizing learning-based modeling for the prediction of relevant time series in order to support comfort satisfaction and resource efficiency in building energy management. A set of neural networks is generated and trained using monitoring data and building context information modeled in an ontology. Autonomous and building-independent application is achieved by continuous performance evaluation and conditional adaption of the neural networks. The evaluation presents exemplary results and discusses the major findings.

With the increasing demand for IT infrastructure, powering IT equipment is one of the largest operating expenses for data centres. According to the data published by Electric Power Research Institute (EPRI), USA global data centres cloud power market is exploding at over 10 percent annually to an estimation of 200 billion kilowatt-hour by 2020. Enhancing the efficiency of the server power supply by at least 1 % could result in an astronomical savings of energy and expenditure. SCALDO is a patented technique developed at the University of Waikato to enhance the efficiency of LDOs. This concept can be used inside silver box power supplies to enhance the quality of output power. However, to practically realize above system, several switches need to be implemented. This paper discusses a novel concept to use SCALDO efficiently inside silver box power supplies.

This paper discusses the implementation of a custom battery emulator, specifically designed for functional testing of battery management systems at the end of the production line. Particular care has been paid to make the design of the battery emulator modular and low cost. These characteristics are sought in relatively low-volume medium-power battery applications, where the adoption of conventional hardware-in-the-loop solutions is not viable. A prototype of battery emulator has been implemented, validated, and successfully used to test a battery management system for 12 series-connected cells.
