One of the requirements for safe, stable, sustainable, and profitable operation of doubly-fed induction generators (DFIGs)-based wind energy conversion systems (WECSs) is the accurate and reliable protection against electrical faults, in particular ground faults. The performance of protective devices employed to achieve this requirement is highly dependent on the grounding configuration of the DFIG-based WECS. This paper investigates impacts of the grounding configuration on the performance of protective devices used to protect DFIGs-based WECSs from electrical ground faults. Investigated grounding configurations include solid-grounding, low-resistance grounding, high-resistance grounding, and no-grounding. The impacts of the grounding configurations on protective devices are observed through their ability to identify faults, as well as their speed to respond to identified faults. Simulation and experimental results reveal that adequately designed low-resistance grounding offers the minimum impacts on protective devices used for ground protection of DFIG-based WECSs.

The amount of the electrical energy used for in interior lighting of medium and large buildings is generally considerable. The European Standard EN15193 was devised to establish conventions and procedures for the estimation of energy requirements of lighting in buildings, and to give a methodology for a numeric indicator of energy performance of buildings. The methodology of energy estimation is based on statistical data and default values and adopts a general approach that requires few parameters. It assumes reference average values for all the Europe regions, while they can vary substantially according to the national laws and uses, it does not consider the actual layout of the control system that contributes to additional energy savings. The paper suggests an improvement of the procedure for the estimation of the lighting energy in the cases that it is possible to know or define the prospected operation time, and three derating factors: daylight, constant illuminance and occupancy. The factors are evaluated considering the actual type of control like the number of control groups, the technique of modulation (dimming or switching), the delay in turning off. The suggested procedure is compared with the Standard one to highlight the improvements.

The architecture of a mission critical power system has to guarantee service continuity and so has to be designed with multiple structures that allow the simultaneous operation of multiple sources. The architectural measures can be applied on the distribution levels, on total or partial redundancy introducing loop configuration and floating nodes. Opportunely organized, the Business Continuity Management (BCM) will project its program and take actions on the sources. Complete control of the system is necessary for all operating occurrences in an electrical power system, control based on a full understanding of system performance during such operations, particularly when they are complex. Complexity requires that the “safe sets” of operating procedures have to be identified out of all the probabilistic possibilities, selected and authorized adopting the Parise program. The paper deals with a sample case of a system with multiple sources applying the micro approach of the “flock” logic.

The current limitations of infrastructure detain the power grid from meeting the requirement of the restructured power market and the integration of the renewable energy. The researches for the smart grid are necessary to develop the future power system. This paper presents the design, development, and hardware setting of the smart MicroGrid test bed at the University of Texas at Arlington. While the test bed can utilize the renewable energy sources like wind turbines, solar panels, and PEM fuel cell, it also has the capability of running in parallel with the utility grid. Since the smart micro grid acts as the basic unit of the smart grid, the test bed provides a playground for both research and education purposes. With real-time data acquisition and control devices, the operation of the smart MicroGrid test bed is also discussed in the paper.

This paper presents a review of power-system synchronization. When two sources are paralleled, it is crucial to close the interconnecting circuit breaker when both sources are in voltage, frequency, and phase coincidence. Operators can synchronize manually, or use the latest, state-of-the-art autosynchronizers (ANSI/IEEE device 25A) [1] and sync-check relays (ANSIIIEEE device 25) to automate closing. Generator and bus synchronization share most principles, with some important differences for each type of synchronization. For generation plants, closing manually or applying an automatic synchronizer depends a lot on the plant configuration and operating mode. For bus-line applications, synchronizing depends on power-system stiffness, motor loads, and whether a wye-delta transformer is between the line and bus. Methods for attaining proper synch-check and fast synchronization are discussed.

In the maritime industry, high fuel costs encourage the use of Variable Frequency Drives (VFDs) for energy saving applications. However, introduction of such nonlinear loads in the vessel's power distribution network induces harmonics, which can lead to potential risks if are not predicted and controlled. In this paper, several harmonic attenuation options are initially investigated for VFDs used in marine vessels. A systematic power quality analysis and monitoring methodology is then proposed to assess the size of required harmonic filters in order to satisfy voltage harmonic distortion limits imposed by marine classification societies when VFDs are applied to motors. The effectiveness of the proposed power quality analyzing procedure and monitoring methodology is evaluated through a real practical example, which includes harmonic filter design for VFDs applied to engine room fan and pump motors that operate constantly at sea-going mode in a typical tanker vessel. Experimental results obtained from power quality measurements verify that design complies with relevant marine harmonic standards even in the worst case of operation.

Service restoration during a fault in ship electric power systems due to external forces or internal faults is an important task for ship power systems design. To enhance the system reliability, an intelligent distributed multi-agent system (MAS) concept is utilized in this paper and a methodology for design of a MCS for ship power systems restoration is proposed. When a fault in the system is detected and isolated, an appropriate restoration plan is derived and performed by power electronic building blocks (PEBBs) used in the MAS through feeder reconfiguration according to the system emergency operation procedure. To ensure the performance of proposed method, a discrete event simulation technique is used to evaluate the data transfer time delays among different agents in the MAS for different fault conditions in the system. A practical ship electric power system is selected for computer simulation to explore the benefit of MAS to ship power restoration. Test results have shown that with the MAS, the restoration procedure can be completed in a shorter time than the traditional restoration method and therefore, the system reliability is enhanced.

The abundant wind resources in Penghu area, which features the impressive capacity factor up to 45%, attract the authority to build more wind turbines in the diesel-based power system. However, due to the instability of the wind turbine output, the high penetration of wind power in the system may affect relatively the system's power quality (voltage and frequency) and reliability. The past studies suggested that the optimal penetration level for wind generation be 26.3% under the present dispatching criteria in Penghu. This study suggests that the criteria of current unit scheduling have to be adjusted by increasing the spinning reserve capacity of the diesel engines without affecting the reliability and power quality of Penghu power system, consequently avoiding the construction of high-cost energy storage systems. The proposed method can determine the number of online diesel units and the needed reserve capacity under different load levels by considering the reliability of power supply, the criteria for the limit of wind power penetration, the distribution in different sites for the wind turbines, and the required spinning reserve to compensate the energy loss when a single diesel unit trips offline or any N-1 accident occurs.

This paper provides an analysis of the equivalent circuit of the 1 MW battery tied to the grid. It also discusses the installation of a 1 MWh battery system at Reese Technology Center (RTC) in Lubbock, Texas. The research involves deploying energy storage devices for application in wind farms to understand the interaction between wind energy, the grid and the grid loads. A 1 MW/1 MWh battery storage system at the RTC is connected to the South Plains Electric Cooperative (SPEC) grid. The batteries are used for energy storage and for mitigation of transient conditions grid dynamics. In this paper the 1 MW battery is modeled in PSCAD and analyzed for its discharge characteristics when it is tied to the grid.
