fPotencia is a C++ library that helps to define a power grid and perform power system load flow analysis on it. It currently offers two Newton-Raphson solver algorithms:

• Newton-Raphson using polar coordinates (including µ acceleration parameter)
• Newton-Raphson with current injection

• CMake >= 3.0.0
• Eigen >= 3.2.8
• Boost.Graph >= 1.59.0

Optionally, if you want testing:

• GTest

Optionally, if the API documentation is desired:

• Doxygen (for API documentation)

Of course, a working C++ compiler and the C++ Standard Template Library is also required. The C++ compiler must understand C++11.

To create a release build of a shared library, e.g., for packaging, issue:

mkdir Build && cd Build
cmake \
    -DCMAKE_BUILD_TYPE=Release \
    -DBUILD_SHARED_LIBS=ON \        # If OFF, a static lib will be built
    ..
make
make test                           # Optionally
make doc                            # Optionally
make install

If you would like to contribute to fPotencia, -DCMAKE_BUILD_TYPE=Debug is obviously the preferred choice.

The best way to get an immediate overview of how fPotencia works is to check out the test grid definitions in test/SolverTest.cpp. They show how a grid is defined.

Of course, for a deeper dive, the API documentation is preferrable. However, if you just want to use fPotencia to perform a load flow analysis of a grid you supply, the example grids in test/SolverTest.cpp are the only instruction you're going to need.
