Static Synchronous Compensator (SSC)
==============================================
We implement the FACTS devices based on the following source:
A. Panosyan, "Modeling of advanced power transmission system controllers",
Ph.D. dissertation, Gottfried Wilhelm Leibniz Universität Hannover, 2010.
The Static Synchronous Compensator (SSC), also known as STATCOM, is a shunt connected Flexible AC Transmission System
(FACTS) controller. It connects an AC system to a Voltage Source Converter (VSC) through a coupling transformer.
The SSC is used for reactive shunt compensation. Since the VSC is not connected to a power source, there is no active
power exchange between the SSC and the AC system. Consequently, the SSC can only control the voltage magnitude of
the AC system.

We demonstrate the use-case of this device in the
pandapower tutorial: `FACTS <https://github.com/e2nIEE/pandapower/blob/develop/tutorials/FACTS.ipynb>`_.

Electric Model
=================

The SSC is a VSC-based shunt-connected FACTS controller and can thus be modeled as a single-terminal active component.
The corresponding terminal-admittance equation is given as:
.. math::
:nowrap:
\begin{align*}
\underline{Y}_{T} (\underline{U}_{1} - \underline{U}_{VSC}) = \underline{I}_{1}
\end{align*}
Where :math:`\underline{Y}_{T}` = 1/:math:`\underline{Z}_{T}` is the admittance of the lossless-assumed coupling transformer between
the VSC and the ac system. :math:`\underline{U}_{VSC}` stands for the VSC output Voltage.
