Improvements of PSA 4.0 comparing to PSA 3.X
• LU factorization of Jakobian matrix is almost three times faster;
• Interface function Copy/Paste for data exchanging with MS Excel i Word tables;
• Export/Import function CIM XML RDF format;• Three-winding transformer model;• Turn off/on line on the one side;• Short circuit calculation function;• “backward looking” algorithm for generator reactive
power limits control.

About PSA Implementation• PSA was completely made in C++ environment
and contains only one executive file, i.e. without DLL files from other programming languages .• It doesn’t require .Net Framework.• Standard Windows libraries and WinAPI are
used (without MFC, ATL, WTL...).• PSA 4.0 was made in VS2010, so that, SP2 for
WinXP has to be installed on workstation.

PSA References• It has been used by Serbian, Macedonian and
Montenegro Transmission System Operators during last six years.
• Studies:• Wind park Vardenik (Serbia) integration into
transmission system• CHP Zenica (Bosnia and Herzegovina) integration
into transmission system
• Versions 3.x were used for simulations of Southeast Europe dry-run coordinated auction office in 2008/2009.
