PSS(R)E high-performance transmission planning software has supported the power community with meticulous and comprehensive modeling capabilities since its introduction in 1976. PSS(R)E-33 introduces several new forms of analysis, Preventative Security Constrained OPF and N-1-1, a number of new analytical models, the standardization of the Dynamic CONEC and CONET type @' y5 U: s( V7 R!

PSS(R)E-33 is built with the Intel Visual FORTRAN (IVF) 12.0 compiler and requires the same for compiling user-written models. Our original investigations and discussions with Intel led us to believe that models compiled with IVF 9.1 or 10.1 could be linked against the IVF 12 compiled PSS(R)E engine and module files and so we communicated this information to you. Unfortunately, during our extensive release testing we discovered that this was no longer possible and that PSS(R)E-33 requires the use of the IVF 12.0 compiler for user-written models. $ V* z% B' |# z# FIn addition, during our testing with various user written models, we discovered that the IVF 12.0 compiler is less forgiving with un-initialized variables than IVF 9.1 or 10.1. User models that are to be compiled with IVF 12.0 for use with PSS(R)E-33 should be closely examined for un-initialized
