Editorial
Obviously, there are significant similarities and differences between protection and distribution automation. Both began rapidly evolving about a quarter century ago to become, together with substation automation, some of the main building blocks of a smarter grid. Designing and implementing a smarter grid is not just a matter of putting together a system using different components, but doing it i... More

Connecting Decentralized Renewable Energy Sources

However, if the generators stay connected, it must be ensured that they are not receiving reactive power, as this would lead to a collapse of the grid. In Germany, a number of legal requirements and grid codes are regulating the connection of such generators. These documents also stipulate the use of Directional Reactive Power Undervoltage Protection (Q->& U< protection) that would disc... More

Is the Smart Grid Real?

I ask myself this question because recently I keep reading articles discussing whether the Smart Grid will be a success or a failure. I think this is a pointless question as the Smart Grid as a concept is already a great success. Never since the invention of electricity has the interest in the power industry been this big. One can always argue about the reason for this interest but in itsel... More
