This is the first released version with great performance improvement. Currently support BUS, LINE, TRANSFORMER, FIXED_SHUNT, GENERATOR, WT_GENERATOR, PV_UNIT, ENERGY_STORAGE, EQUIVALENT_DEVICE, etc. --- README.md | 4 ++++ code/source/basic/utility.cpp | 2 -- 2 files changed, 4 insertions(+), 2 deletions(-) diff --git a/README.md b/README.md index 41569f31..206c0980 100644 --- a/README.md +++ b/README.md @@ -9,6 +9,10 @@ Currently, it supports powerflow solution and dynamic simulation. In the future, The data format of STEPS is improved based on PSS/E raw and dyr data format. BPA dat format is also supported. You are encourage to join us for further development. +## Major versions +V0.0: Initialize project on March 21, 2018 +V1.0: Improved performance version on Feb. 12, 2020. Support synchronous generator, wind turbine generator, (basic) PV unit, HVDC, static and dynamic loads. + ## Dependency STEPS depends on CSparse, CXSparse, CppTest, and RapidJSON. The CXSparse is modified to avoid confliction between CSparse and CXSparse by changing prefix cs_ and CS_ to cxs_ and CSX_ . Though BLAS, CBLAS, and other SuiteSparse codes are included in the package, they will be removed in future. diff --git a/code/source/basic/utility.cpp b/code/source/basic/utility.cpp index b7b8b316..6d8c9e69 100644 --- a/code/source/basic/utility.cpp +++ b/code/source/basic/utility.cpp @@ -348,8 +348,6 @@ double steps_asin(double x) double steps_fast_asin(double x) { return asin(x); - if(x==0.0) - return 0.0; double y = fabs(x); if(y<1.0)
