Grid stability and security of supply are two important aspects
for energy supply. In order to avoid power outages it
is necessary that power generating plants should have control
capabilities and protection mechanisms. In the past,
these requirements were mainly fulfilled by conventional
power plants. In the meantime, however, the share of renewable
energy sources in the total electricity generation
has become so significant that these sources too must contribute
to the grid stability. Therefore the transmission system
operators have established so-called grid codes with
certain critical values and control characteristics that the
generating plants have to fulfill. An important part of these
requirements is the so-called LVRT capability of generating
plants. But what exactly does this term mean?
LVRT is short for Low Voltage Ride-Through and describes
the requirement that generating plants must continue to
operate through short periods of low grid voltage and not
disconnect from the grid.
Short-term voltage dips may occur, for example, when large
loads are connected to the grid or as a result of grid faults
like lightning strikes or short-circuits. In the past, renewable
generating plants such as wind turbines were allowed
