One of the key protection functionalities in the future active distribution networks will be reliable detection of islanding. Non-detection zone (NDZ) near a power balance situation and maloperation due to other network events have been the major challenges with traditional passive islanding detection methods like voltage, frequency, rate-ofchange-of-frequency, voltage vector shift (VVS). Howev...

Autonomic computing is a bio-inspired vision elaborated to manage the increasing complexity of contemporary heterogeneous, large scale, dynamic computer systems. This paper presents a series of scenarios relative to micro smart grids – district-size “smart” electricity networks. These scenarios involve situations where autonomic management approaches could provide promising solutions. They ther...

For many isolated regions in the developing world micro-grids which combine photovoltaic electricity generation and battery storage may represent the most reliable and least expensive form of energy service. Due to climate induced solar resource variations, achieving high reliability levels necessitates excess generation and storage capacity which can significantly increase the end consumer cos...

In the micro-grid, power storage converter is played as a interface between the battery pack and grid electricity storage device, to achieve a two-way exchange of energy. In this paper, the research and development of power storage converter can realize multiple sets of independent control of the battery, flexible configuration of the system capacity and flexible cutting of the battery pack. St...

Generally, such as bio-fuels, wind, solar, small hydropower, marine and geothermal energy, etc. have been defined as new renewable energy. Photovoltaic and wind power generation have been in rapid growth, but they have characteristics of randomness, intermittent, uncontrollable. Although the idea of effective renewable energy use as a means of coping with environmental and resource problems, es...

A heterogeneous implementation of the current LCG2/EGEE grid computing software is supported in the Grid-Ireland infrastructure. The porting and testing of the current software version of LCG2 is presented for different flavours of Linux, namely Red Hat 7.3, Red Hat 9 and Fedora Core 2. The GridBench micro-benchmarks developed in CrossGrid are used to compare the different platforms.
