Silicon Carbide (SiC) devices provides for better performance in photovoltaic (PV) and distributed energy resource (DER) inverters. Switches based on SiC can tolerate higher temperatures, accommodates high voltages, and can operate at higher frequencies. The boost inverter presented is a single stage inverter topology that lowers or attenuates the input dc voltage creating an ac output voltage. Grid reliability is improved through the integration of silicon carbide devices in technologies such as the boost inverter which provides for improved efficiency and lower cost for grid connection. A novel Gallium Arsenide (GaAs) photovoltaic device is also discussed and chosen as the dc source to the boost inverter due to its high absorptivity and insensitivity to heat thus allowing for increased energy conversion. A low power prototype is designed to show that the proposed system serves as a feasible renewable energy system for commercial and industrial applications.

In this work the application of Mixed Integer Linear Programming (MILP) techniques is proposed for choosing the optimal topology of an air compressor room, while (i) focusing on energy efficiency and (ii) keeping the input power to the lowest value. Usually the proposal of the best configuration (type of machines, size and number) is driven by the experience of the personnel performing the assessment, according to his own knowledge of the available products/machines on the market. The paper proposes the formulation of two optimization problems which enable (i) to perform the best configuration of a compressor room, according with an available machines database; (ii) to ensure that the best choice implies the minimization of the input power for the compressor room, thus, the minimum consumption for the end-user. The presented formulations are tested using both simulated and real case studies, showing how a higher level of knowledge of the flow profile can help in the reduction of the energy consumption. It will be also demonstrated that important energy savings improvements can be obtained if we compare the choices derived from our methodology with real compressor rooms, whose choice was done without applying such method, as it may happen on the market.

Plastic packaging materials are produced on roll-to-roll coating, printing and converting machines that convey insulating, polymer webs at speeds often exceeding 3 m/s. Static charges on these web cause a number of problems including sparks that ignite fires, that shock people, and that cause logic errors in the production machine control systems. Static charges attract airborne contaminates and, in sheeting and labeling operations, cause sheets and labels to stick and block. While many static dissipators are commercially available for controlling static on webs and sheets, their performance is highly variable. Here, the performance of static dissipators is analyzed to find that three key factors determine neutralization efficiency; the ion number density generated by the static dissipator (dissipator design), the length of the web exposed to ions (installation), and the web speed (process). A key result is that the static dissipator neutralization efficiency varies with the electric Reynolds number, the ratio of the dissipator time constant determined by the number of ions generated by the dissipator to the time that the web is exposed to ions from the dissipator. A second result is that the spacing between the static dissipator and the charged web is not a key factor. Rather, the web length exposed to ions from the dissipator is the key factor. Finally, a method is presented to measure the number of ions generated by a static dissipator to determine the dissipator time constant. Results from a commercially available static dissipator are given.

This paper presents an analysis and design of a Light Emitting Diode (LED) driver aiming to substitute the electrolytic capacitors. Considering the low lifetime of electrolytic capacitors compared to LEDs, this topology aims for reducing the storage capacitance and replaces it by a longer lifetime capacitor, increasing the overall system life span. This reduction is based on designing a control dynamic with a compromise between the input current distortion and the output current ripple. The power factor correction (PFC) stage is based on a Single Ended Primary Inductance Converter (SEPIC) because of its intrinsic low input current distortion characteristic making it possible to eliminate the electromagnetic interference (EMI) filter. The power control (PC) stage is performed by a Ćuk converter using its output current source behavior in Continuous Conduction Mode (CCM), suitable for LED application. Furthermore a dimming strategy is also proposed and implemented by an LED parallel active switch.

Building Automation Systems BAS are the key to improve the energy performance of buildings and the occupants' comfort. There is a need to build a knowledge base on the matter and to grow suitable algorithms for a smart management of the “intelligent buildings”. Indeed, fuzzy logic is a valuable candidate for developing robust algorithms. The scope of the present work is to validate a fuzzy logic approach able to optimize the level of energy performance and comfort in an office space, taking advantage of BAS and solar energy. In BAS, dynamic elements (e.g. dynamic façade and luminaires) can exploit daylight and solar gain; on the condition that well-programmed integrated multicriteria decision making methods are used. In this paper, a virtual model of a Smart Office Room SOR, equipped with dynamic shading, lighting and air conditioning control system, was studied and different scenarios were considered: i) control versus no-control; ii) economy versus comfort mode; iii) fluorescent versus LED; iv) dimming versus switching. Both economy and comfort mode showed a better energy performance than non-controlled scenarios. In conclusion, the proposed model is a valuable tool to optimize comfort features and energy demand as a whole.

In the variable speed wind turbine, generator speed can be operated at maximum power operating points by adjusting the shaft speed optimally. This paper presents a speed sensorless based adaptive maximum power point tracking (MPPT) control of interior permanent magnet synchronous wind generator (IPMSWG). For the proposed control system a model reference adaptive system is incorporated to estimate the rotor position. Furthermore, without requiring the knowledge of wind speed, air density or turbine parameters, the MPPT algorithm generates optimum speed command for speed control loop of vector controlled machine side converter. The MPPT algorithm uses the estimated active power output of the generator as its input and generates command speed so that the maximum power is transferred to the dc-link. The performance of the proposed speed sensorless adaptive MPPT control of IPMSWG is tested in both simulation and experiment at variable wind speed conditions.

In electrical power systems, such as data centers and hospitals, where service continuity is essential, the electrical operation management must be organized and it is necessary to have an emergency response team available at all times (24/7). In hospitals, for instance, doctors, surgeons, administrators, medical devices are rightly at the forefront, but electrical and technological systems and team of technicians are wrongly considered as ancillaries. The paper emphasizes the importance of the Business Continuity Management (BCM) and highlights how IT-M systems have not to carry out power outage for fault both due to overcurrent and also due to overvoltage. When a fault occurs during a surgical operation, the protection system shall include a count-down time so that emergency response team must solve the problem before the system collapses.

This paper presents the application of the lease-squares estimation technique in identification of the cable shovel parameters and monitoring its payload. A data acquisition system was installed on a P&H2100 cable shovel and logged the cable shovel data for several loading cycles. The payload was dynamically estimated using the simplified dynamic cable shovel model we developed. The accuracy and repeatability of the algorithm has been verified based upon the cable shovel data logged during its normal operation at the mine.

This paper presents a design of robust voltage control system for improving transient and voltage stability in the power system where distributed generations (DGs) are gradually increased. If DGs are installed more and more, the problems related to transient phenomenon or voltage variation due to output variation of DGs may become severe and can make the system unstable. In this paper, a solution to mitigate those problems is proposed by renovating voltage management system (VMS) already installed in Jeju Island, South Korea. The solution consists of two additional controllers, which are transient mitigation controller (TMC) and voltage regulation controller (VRC). The TMC induces supplementary signal to reactive power dispatcher (RPD), which is a component of the VMS, to mitigate transient phenomenon shortly after disturbances such as load or DG trip. The VRC is designed to reduce voltage variation caused by output variation of the DGs. The performances of the proposed robust voltage control system are carried out by time domain simulation in the Jeju island power system with real-time digital simulator (RTDS) which is a fully digital power system simulator in real-time.
