Power Systems Analysis SoftwareFrom Open Electrical Power systems analysis and simulation software are ubiquitous in electrical engineering practice. Initially, they were used to quickly solve the non-linear load flow problem and calculate short circuit currents, but their use has been extended to many other areas such as power system stability, protection and coordination, contingency / reliability, economic modelling, etc. This article provides a list of the most common software packages used for power systems analysis, and surveys both commercial and non-commercial software (listed in alphabetical order by vendor name).
