Climate Change and Sustainable Energy Policies in Europe and the United States

IEEP and its partner, the Natural Resources Defense Council (NRDC) have published a report on “Climate Change and Sustainable Energy Policies in Europe and the United States”. This report includes the main conclusions of our joint project - Transatlantic Platform for Action on the Global Environment (T-PAGE). T-PAGE has provided a platform for debate to stimulate dialogue and exchange of experiences between environmental NGOs, academia and other interested civil society organisations in the U.S. and EU.

Overvoltages due to Wind Power - Hosting Capacity, Deterministic and Statistical Approaches

This paper introduces methods to quantify the impact of wind power and other types of distributed generation on the overvoltage risk. The so-called hosting capacity approach, introduced in the very first issue of this magazine, is used as the basic approach. Both a deterministic and a statistical approach are introduced. The deterministic approach is suitable for generation with a constant production most of the time. However, it is shown that a deterministic approach could easily result in an unnecessary barrier against the introduction of wind power. For any method used to determine the hosting capacity, a serious discussion is needed about overvoltage indices and objectives.

Laboratory of Distributed Generation in Institute of Electrical Power Engineering of Technical University of Lodz

In the paper major laboratory equipment is described: photovoltaics, microturbine, fuel cell, battery energy storage, together with the configuration of the laboratory network facilitating studies of characteristics of those energy sources and problems of cooperation of distributed generators with electrical power network. For integration of distributed sources into the power system it is necessary to properly control their operation.

IEC 61850 as a flexible tool for electrical systems monitoring

In the last decades there have been great advances in electronic, information and communication technologies. Up to date, any of these advances have been implemented in electrical systems, but some difficulties have been encountered, particularly regarding to the integration of intelligent electronic devices from different manufactures into a centralized system. With the aim of solving the above mentioned problem, the standard IEC 61850 was developed to specify communication networks in substations.

Distributed Generation Impact on Voltage Sags in Distribution Networks

Characteristics of voltage sags caused by faults in distribution networks depend on the design of the protection system and the coordination between the different protective devices. The presence of distributed generation (DG) changes the radial nature of distribution systems, so it can affect the performance of the protection system, and consequently the characteristics of voltage sags. In addition, DG will help to maintain the during-fault voltages of healthy phases.
