Changes in Energy Technology – Part 1

In this article we discuss the current changes in the energy technology. In addition, we will look on the effects of grid repercussions and what influence they have on measuring devices with which we detect faults in the grid.

Performance increase in the distribution grid

Due to economic unreasonableness, grid operators are rejecting applications to connect PV systems in the low-voltage grid more often. The responsible grid planners are guided by the connection guideline VDE-AR-N 4105, in which decentralized generation facilities may only raise the voltage level in the low-voltage grid by 3% compared to the previous situation.

Economic Analysis Low Voltage Regulation

Smart Grids and the resulting changes in the distribution grids face many distribution grid operators with different challenges. These include…
