These huge machines are amazing compared to the wind mills used for centuries or the first electricity-generating wind turbines from 125 years ago. They are also connected to the electric power system in a very different way. While at the end of the 19th century and most of the 20th century wind generators were isolated single machines predominantly used to produce electricity in rural areas wi... More

Cover Story

Integration of Distributed Energy Resources

The integration of DERs requires good understanding of the impact they have, especially on the distribution system protection, as well as on the modeling of their functionality. While large wind and solar farms connected to the transmission system do not require major changes in the functionality of the protection systems, this is not the case at the distribution level of the system. The radial d... More

Impact of Distributed Generation during the European 2006 Disturbance

The requirements for disconnection of generation units connected to the distribution grid (especially wind generation and CHP) are usually less strict than for the units connected to the transmission grid, i.e. they are disconnected at a smaller frequency deviation. When the frequency deviation reaches the threshold values of the units’ protection, they are automatically disconnected from th... More

Final Thoughts
The way things are going, it is clear that distributed generation is here to stay. And that is why we need to change the rules. For most of the last century transmission, distribution and generation were all owned by the electric power utilities. This made it easier to establish rules followed by everybody that ensured that all these components of the system work together supposedly in the most e... More
