A transition to hydrogen as a major fuel could transform the US as well as global energy system increasing energy security while reducing environmental impact. This major transformation of our energy system would require a sustainable production of hydrogen using renewable resources. Hydrogen production using photo-electrochemical water splitting has been considered as a “holy grail” of sustainable hydrogen economy. Despite four decades of research since it was first shown that n-type TiO2 can be used for water splitting using sunlight, the search for a material that can efficiently harness solar energy for photo-electrolysis is still on. This paper will address some of the key challenges in the development of a material that is photoactive, stable, corrosion resistant and cost effective. This paper presents for the first time photo-electrochemical characterization of novel phosphorus, nitrogen doped carbon material (PNDC). The photocurrent density obtained was 0.416 mA/cm2, which is quite significant under visible radiation. This discovery opens up a large number of possibilities in development of a new class of carbon based materials for photo-electrochemical hydrogen production.

Plug-in Electric Vehicles (PEV) battery chargers are mostly connected to the low-voltage grid for charging. Their increased penetration coupled with uncoordinated charging could impact the distribution system in terms of unbalanced voltage and transformer overloading. Although PEV battery charging is increasing, impact on the distribution system is not fully investigated. This paper focuses on unbalanced voltage caused by uneven distribution of PEV penetration among the phases. Using real data provided by utility, a distribution system has been modeled and tested using Matlab-Simulink. PEV penetration levels at 10-80% are studied, unbalanced voltage is calculated, and transformer overloading is observed. As PEV adoption is expected to increase, the impact on the distribution system will increase. Coordinated or smart charging of PEVs will be essential for consumers and utilities.

Better understanding of actual customers' power consumption patterns is critical for improving load forecasting (LF) accuracy and efficient deployment of smart grid technologies to enhance operation, energy management, and planning of electric power systems. Though technical literature presented extensive methodologies and models to improve LF accuracy, most of them are based upon aggregated power consumption data at the system level with little or even no information regarding power consumption of different customers' classes. With the deployment of Advanced Metering Infrastructure (AMI), new energy-use information becomes available. AMI data introduces a fresh perspective to perform LF, ranging from very-short- to long- term LF at the system level, or down to the consumer level. However, one critical step to realize these benefits is to develop data management and analysis process to transform AMI data into useful information. This paper addresses the efforts involved in preparing residential customers AMI data as inputs for LF, and introduces the idea of how the preprocessed data could be further enhanced by identifying customers' consumption patterns through the application of clustering. Grouping load profiles based on consumption behavior similarities will reduce the variability of load which is going to be predicted, and therefore, reducing the forecasting error.

The aim of this paper is to overview fault tolerant power architectures for adjustable speed drives (ASD). Here, our goal is to assess the reliability of ASD provided in transportation systems. A Markov model is derived for each architecture. As the inverter is the least reliable component of ASD, a special stress is put to model it for reliability assessment. Each model consists of building blocks developed for power switches and isolation switches. The assessment results allow comparing studied drives particularly from dynamic reliability point of view taking into account operating conditions of the system. This point will be developed in future work.

Driving induction motors with PWM inverters through long distances result in several undesired high frequency phenomena, such as transient overvoltages at the motor terminals, common-mode currents flowing through the system and the presence of a cable charging current, among others. Instead of filters, which represent the traditional method for the mitigation of these problems, in a previous work the authors proposed an alternative solution, where the rectifier and inverter bridges are separated and connected by the long cable, being the latter located right besides the motor. This alternative configuration, based on DC transmission, aside from solving the aforementioned problems, provides the additional benefits of reducing the voltage drop in the cable and providing copper economy for the power transmission. In this context, in the present work a prototype of a long cable motor drive system was built in both configurations (conventional and with DC transmission). Several results involving the transient overvoltages, cable charging and common-mode currents were obtained from each system and compared, in order to demonstrate the effectiveness of the proposed drive system topology in reducing these undesirable phenomena.

The growing interests in clean and sustainable electric energy push towards increasing the interconnection of wind energy conversion systems (WECS) to utility grids. Designs of the majority of WECSs employ power electronic converters (PECs), which generally have non-linear and switched characteristics. The characteristics, operation, and control of PECs in WECSs can result in non-conventional current-voltage behaviors during faults. This paper investigates the current-voltage behaviors during faults that occur in WECSs or their host grids. Two types of WECSs are considered in this paper, which are the doubly-fed induction generators (DFIGs) and permanent magnet generator (PMGs) based WECSs. The current-voltage behaviors are investigated in experimentations for different faults occurring during the grid-connected operation.

In this paper, the performance of a passive anti-islanding method is experimentally tested for three phase (3φ) co-generation systems. The tested method is based on determining the wavelet packet transform (WPT) high frequency sub-bands present in the d - q-axis components of instantaneous 3φ apparent powers (sd and sq), when evaluated at the point of common coupling (PCC). This passive anti-islanding method is founded based on the nature of instantaneous 3φ apparent powers that have components continuously exchanged between both sides of PCC. An islanding condition can be considered as a transient disturbance that creates non-periodic and non-stationary high frequency components in sd and sq. These frequency components can be parametrized by WPT high frequency sub-bands, which can provide accurate detection of the islanding condition. The d-q WPT-based anti-islanding method is tested for a 3φ co-generation system under various loading and power delivery conditions. Performance results reveal accurate, fast, and reliable detection and response to the islanding condition.

This paper presents a preliminary comparative study of total energy density variations before and after twenty-five Homa (Fire Offering) ceremonies at a large esoteric Buddhist temple in Taiwan. The Homa ceremonies were personally presided over by an internationally renowned Dharma King, His Holiness Living Buddha Lian-sheng. The Homa ceremonies at this temple were held on Saturdays from 15:00 to 18:00 from May through November since May 8th, 2010. The study was based on field measurements of a total of twenty-five Homa ceremonies beginning May 5th, 2013. A high frequency electromagnetic wave test meter was employed to measure the electric-field strengths at fifteen specific measurement points located in the square in front of the main building of the temple. According to the field measurement results, it can be observed that the electric-field strengths at most measurement points exhibit certain regular variations, while at a few measurement points they exhibit an opposite characteristic.

A magnetic proximity detection system relies on magnetic flux density measurement to determine the position of a worker relative to a mobile mining machine. It is desirable for the magnetic flux density distribution to be automatically adjustable to conform to the protection requirements for the different types of machines and working environments. In support of the development of an automatic field distribution adjustment process, we developed a transferrable magnetic flux density distribution model. The transferrable model can also be used to control and stabilize the field against field drift to enhance system performance.

Processes requiring a variable applied voltage often use power electronic devices. This causes reduced power factor and higher levels of current harmonic injection. Although power quality issues are typically rendered after the fact, by careful consideration during the design phase, equipment and/or processes can often be designed to achieve a better performance. This paper deals with methods for improving power factor and energy efficiency during the design phase for batch type industrial process heating applications with variable power requirements.
